Longer Laser Rotary Roller - LONGER
Longer Laser Rotary Roller

Longer Laser Rotary Roller is a fundamental accessory for all those who carry out laser engraving work, as it is possible to make engravings on curved surfaces with ease, which would be impossible to perform without this accessory.

Everyone who uses a laser engraving machine knows well that in order for the laser to engrave a surface it is necessary that the laser beam is focused. Assuming that, in order for the laser beam to be in focus it is necessary that the distance between the laser module and the surface to be engraved is 50mm, once the right distance has been established it is possible to engrave any point of the surface as the equidistance is respected at every point. However, if the surface to be engraved is not flat but curved, then the equidistance is not respected; in fact, as you can see from the image below, the focus (fixed in point A) is lost as soon as the laser module moves with respect to the focus point.

To solverand this problem it is necessary to use the Longer Laser Rotary Roller, which causes the surface to be engraved (through a rotation) to move instead of the laser module. In this way, each point of the curved surface to be engraved is brought to the focus point of the laser, i.e. the surface to be engraved makes a "rotation". For this technique to work correctly it is necessary that the surface to be engraved is cylindrical in shape, otherwise the problem of focusing would be solved with respect to the Y axis with the Rotary Roller, but it would occur with respect to the X axis.

The installation of Longer Rotary Roller is really easy: just connect it to the Y-axis connector of your Longer Ray5, and in this way the laser module will move to the X axis, but the movement with respect to the Y axis will be applied to the Rotary Roller instead of the Y axis of the laser module. As for the settings, they are almost the same settings used for engraving on a flat surface. In fact, if you want to engrave a 10x10cm image, instead of getting a 10x10cm image on a flat surface you will get a 10x10cm engraving on a curved surface, so the result in terms of size does not change. To better understand this concept, it is similar to when you remove the label from a jar: the label on the jar is curved, when you remove it and place it on a plane it becomes flat, but in both cases the label is always the same and the dimensions do not change.  

In order for the movement steps to be respected, the Rotary Roller must be set differently according to the size of the object on which you intend to make the laser engraving. In detail, about the gear of the roller, you can refer to these dimensions in order to keep the correct steps:

1: Distance between two axes is 5mm, suitable for engraving 6-38mm diameter objects

2: Distance between two axes is 23mm, suitable for engraving 38-70mm diameter objects

3: Distance between two axes is 41mm, suitable for engraving 70-102mm diameter objects

4: Distance between two axes is 59mm, suitable for engraving 102-134mm diameter objects

5: Distance between two axes is 77mm, suitable for engraving 134-166mm diameter objects

6: Distance between two axes is 95mm, suitable for engraving 166-200mm diameter objects

 

Using the Longer Laser Rotary Roller allows you to expand the functionality of your Longer Ray5, as you can easily engrave many everyday objects, such as pens, jars, cylindrical objects and much more.

Differences between PETG and PLA in FDM 3D Printing - LONGER
Differences between PETG and PLA in FDM 3D Printing

In general, the choice between PETG and PLA depends on the specific needs of the 3D printing you intend to make. If you want greater impact resistance, flexibility and chemical resistance, PETG may be your best choice. Instead, if you want a cheap, easy to print and biodegradable material, PLA may be the best choice. In particular, PETG is a very resistant and flexible filament, ideal for printing large volume objects and resistant to the effects of chemicals such as acids and alkalis; moreover, compared to PLA, PETG is more resistant to heat and less fragile, so it is great for making prints that will be placed outside and exposed to sunlight.

PETG is a co-polymer that combines the properties of PET and Glycol. The addition of the latter reduces the problems of overheating of PET and, consequently, increases its resistance. For these reasons, PETG is one of the most commonly used filaments, and is an excellent choice for printing parts subjected to mechanical stress and heat; moreover, PETG has an almost absent odor during printing, even if it is a material derived from petroleum and therefore not biodegradable.

PLA is a lactic acid polymer and was the second bioplastic marketed and sold on a large scale. It derives from the milling of corn and is to be considered biodegradable, even if it requires precise conditions to trigger the decomposition process. PLA has some advantages over PETG, such as greater ease of printing, greater rigidity, better surface quality and lower cost, although it fears heat and weathering.

Therefore, summarizing the advantages of PETG over PLA, here is a list of technical characteristics:

  • Impact resistance: PETG is more impact resistant than PLA. This means that PETG is less likely to break during use.
  • Flexibility: PETG is more flexible than PLA, which makes it better for printing parts that require a certain amount of flexibility or need to resist warping.
  • Chemical resistance: PETG has higher chemical resistance than PLA, which makes it more suitable for printing parts that come into contact with chemicals or solvents.
  • Ease of printing: PETG is easier to print than other materials such as ABS and Nylon, but offers very similar characteristics to these. However, compared to PLA, PETG is more difficult to print.
  • Temperature resistance: PETG has greater temperature resistance than PLA, and can withstand higher temperatures without deforming or losing its shape.
  • Weather resistance: PETG is more weather resistant than PLA, which makes it more suitable for printing parts for outdoor use.
  • UV light resistance: PETG has greater resistance to UV light than PLA. This means that PETG is less susceptible to yellowing or degradation caused by exposure to UV light.
  • Dimensional tolerance: PETG has a higher dimensional tolerance than PLA. This means that PETG molded parts can have higher dimensional accuracy than PLA.
  •  

    In general, PETG is a versatile and durable material that can be used for a wide range of applications. However, like any material, it also has some disadvantages, such as the need to use higher printing temperatures than PLA and a greater propensity to create stringing filaments. In addition, PETG may require more attention in the preparation of the print bed and in the calibration of the printer than PLA, however if you choose PETG and take all the precautions seen in a previous article, the printing result can be of high quality.

    In conclusion, both materials have their advantages and disadvantages, and the choice depends on the specific needs of the project. When choosing between PETG and PLA, it is important to consider the strength, flexibility, chemical resistance, ease of printing, heat resistance, weather resistance, durability, availability, cost, sustainability, color, appearance and specific applications of the project you want to achieve.

    PETG 3D Printing in FDM - LONGER
    PETG 3D Printing in FDM

    Longer FDM 3D printers are capable of printing PETG with high quality. This type of material offers many advantages, as it can be printed as easily as PLA but is as durable as ABS.

    To 3D print the PETG, you need to make sure that the 3D printer is set up correctly to print the PETG. This includes material selection, nozzle and hotbed temperature, extrusion speed, and other settings related to print quality. In addition, when printing PETG it is recommended to always keep an eye on the press to make sure that everything goes according to plan and that there are no problems.

    The recommended parameters for printing with PETG in 3D may vary depending on the 3D printer, the type of PETG purchased and the project you want to carry out. However, here are some common printing parameters for PETG:

  • Extrusion temperature: 220°C – 250°C
  • Bed temperature: 70°C – 90°C
  • Print speed: 40 mm/s – 80 mm/s
  • Fan speed: 0% - 30%
  • Retraction distance: 4 mm – 8 mm
  • Retraction speed: 30 mm/s – 40 mm/s
  • Layer height: 0,2 mm                                                    
  •  

    Keep in mind that these are only basic values and small adjustments may be necessary to achieve the best results based on your specific needs. In fact, there are a few other factors that could affect printing with PETG:

  • Adhesion to the bed: it may be useful to use an adhesive solution to be affixed to the glass or a latex/PEI top to increase the adhesion of the material to the printing bed.
  • Fan cooling: it is important to keep the fan off or at a minimum to cool the newly extracted material, as cooling too fast can cause warping and weakening of the structure.
  • Extrusion: it is important that the extruder is able to extrude a constant amount of material during printing, so the temperature must be set high enough.
  • Bed leveling: A well-leveled bed can ensure that the model has an even base and that there are no detached parts during printing.
  • Speed: Printing speeds that are too fast can cause warping or adhesion effects. Adjust the print speed to achieve a balance between quality and print time.
  • Temperature: Extrusion temperature can affect material properties, such as flexibility and strength. Make sure the temperature is high enough to ensure good extrusion, but not too high to cause other problems.
  • Print bed cleaning: Make sure the print bed is clean and free of dust or other things that could affect material adhesion.
  •  

     

    These are just some of the factors that can affect printing with PETG. It is advisable to do some tests to understand which combination of parameters works best for your 3D printer and for your specific project. In addition, it is important to use a quality material and store it correctly, since PETG can be sensitive to changes in temperature and humidity; Therefore, it is necessary to store the filament in an airtight container along with a silica bag to maintain the quality of the material.In general, the key to successful printing with PETG is to experiment and optimize printing parameters according to the specific needs of the project. However, once you have learned how to 3D print PETG, this is a material that allows you to create resistant, flexible and quality objects. For best results, it's important to follow recommendations on printing parameters, such as temperature, speed, and media usage, and pay attention to design and post-processing details.

    FDM 3D Printers – 24V vs 12V - LONGER
    FDM 3D Printers – 24V vs 12V

    FDM 3D printers on the market usually work at 12V or 24V. The choice is made based on the characteristics of the product, the type of user to whom it is intended, and also the production costs; however, even if the operation of a printer is identical, regardless of the working voltage, there are clear differences depending on whether the operation is based on 12V or 24V.

    In physics, it is shown that the electric power (Watt) is the multiplication between the voltage (Volt) and the intensity of electric current (Ampere), i.e. P = V * I ; therefore, with the same power, as the voltage increases, the current decreases (and vice versa). In addition, the charge carriers that make up the electric current generate heat by moving inside the conductors, so the higher the current intensity, the greater the charge carriers, the greater the heat that develops. In fact, for this reason the power lines that transport electricity from one part of the various continents and nations to another operate at high voltage, as this allows the use of cables of lesser thickness (less passage of current) with the same power supplied; then, only locally the transport takes place at domestic voltage (110V / 230V), so as to be compatible with domestic electrical equipment.

     

    Based on these premises, it becomes much easier to understand that an FDM 3D printer operating at 24V can have the following advantages:

  • to heat a Hotend with a resistor of 40W are sufficient only 1.67A (against the 3.33A needed at 12V)
  • to heat a Hotbed with a resistor of 180W are sufficient only 7.5A (against the 15A needed at 12V)
  • This means less heating of the cables and connectors on the mainboard, minimizing the risk of connector fire and overheating of the mainboard's smd components, resulting in irreversible damage.

     

    For these reasons, Longer FDM 3D printers operate at 24V, so that we can offer all customers the best possible product.

    Hotend Replacement for Longer FDM 3D Printer - LONGER
    Hotend Replacement for Longer FDM 3D Printer

    While using an FDM 3D printer, you may need to replace the Hotend. In fact, a little space between Heatbreak and Nozzle, or a failure of the Heatsink fan, or any other type of problem could cause a clog that prevents normal extrusion during printing, and the only way to repair the fault is to disassemble or replace the Hotend.

    Replacing the Hotend is an easy procedure but one that requires the utmost attention.
    In order to proceed with the replacement, follow these steps.

     

    Disassembly

    1) Unscrew the screw that holds the thermistor in place and remove the thermistor and temperature sensor

     

     

    2) Disassemble the Hotend, then unscrew the screw that holds the Heatsink in place and remove the Heatsink

     

     

    3) Remove the PTFE tube from the Heatbreak

    4) In case the end of the PTFE tube is damaged, cut the damaged part taking care to make a vertical cut at 90 degrees; An inaccurate cut will cause molten material to leak during printing, causing a new clog. In order to proceed to a precise cut, it is recommended to use a "PTFE cutter" available as an accessory for 3D printing or you can proceed to print a stl file by searching on thingiverse "PTFE cutter"

     

     

     

    Replacement

    1) Screw the Heatbreak correctly into the Heatblock

     

     

    2) Screw the Nozzle into the Heatblock

    Hotends comparison - MK8 vs V6 - LONGER
    Hotends comparison - MK8 vs V6

    The Hotend is the part of an FDM 3D printer that deals with the melting and deposition of molten plastic material. Therefore a Hotend is composed of a Nozzle that deals with depositing the molten material, a Heatblock that deals with the melting of the material, and a Heatbreak that keeps the hot zone separate from the cold area of the Hotend. The Heatbreak can be equipped with a Heatsink, equipped in turn with a fan.

    Hotends come in various shapes and sizes, however common and popular types are the Hotend MK8 and Hotend e3d V6.

     

    Hotend MK8

    The Hotend MK8 are composed of Nozzle, Heatblock, Heatbreak and Heatsink, and provide for the insertion of the PTFE tube in beat with the nozzle. This implies that the PTFE tube is inserted inside the Heatbreak, then the filament flows inside the PTFE tube and reaches the nozzle directly, without intermediate zones.

     

    The PTFE tube, in the part in contact with Nozzle and Heatblock, tends to reach the same melting temperature set for the filament, however this is not a problem as PTFE supports temperatures up to 300 C very well, well beyond the normal printing temperatures of PLA, PETG and ABS. On the other hand, the higher the printing temperature, the greater the amount of heat that the Heatbreak must dissipate; in fact, when the heat is not dissipated properly, it tends to rise inside the PTFE causing the filament to melt in areas far from the Nozzle, resulting in obstructions that prevent the filament from passing. For this reason, it is necessary to accompany the Heatbreak with a heatsink heatsink with fan, in this way the heat passage is quickly interrupted.

    The Hotend MK8 is ideal for printing most filaments, however for printing more technical materials it may be unsuitable. In fact, printing filaments that require a high temperature, such as polyamide (nylon), also require a large dissipation capacity; however, the structure of the MK8 Heatsink is not able to dissipate much heat, moreover the PTFE tube present inside the Heatbreak also begins to lose its characteristics, thus causing obstructions.

     

    Hotend e3d V6

    The Hotend e3d V6 are composed of Nozzle, Heatblock, Heatbreak and Heatsink, and provide both the insertion of the PTFE tube in batting with the nozzle and the PTFE tube in batting with the Heatbreak. This implies that the PTFE tube is inserted inside the Heatbreak, then the filament flows inside the PTFE tube and reaches the nozzle directly, without intermediate zones, or the PTFE is beaten at the entrance of the Heatbreak and the filament passes through an all-metal area before reaching the nozzle. Therefore, the Hotend e3d V6 provides two different configurations of Heatbreak, or the classic Heatbreak with PTFE or a Fullmetal Heatbreak.

     

    The Hotend e3d V6 has an improved heatsink, with a larger dissipative surface, so it is ideal for printing most filaments, including printing more technical materials. In fact, even the printing of filaments that require a high temperature, such as polyamide (nylon), can be performed thanks to the great dissipation capacity; moreover, if the temperature is excessive for the PTFE tube present inside the Heatbreak, then it is possible to use a Fullmetal Heatbreak that does not suffer from temperature problems.

     

    Unfortunately, due to its large size, it is often very difficult to install a Hotend e3d V6 on smaller printers, for this reason the default installation of a Hotend MK8 is often preferred, which is able to perform almost any printing option for common users with a small footprint.

    LONGER RAY 5 Newest 20W vs. 10W vs. 5W, What's the Differences? Which One to Buy? - LONGER
    LONGER RAY 5 Newest 20W vs. 10W vs. 5W, What's the Differences? Which One to Buy?

    If you want to correctly engrave practically anything, you will need a laser engraver. This is because lasers are extremely precise. Because they sell the RAY5 5W and RAY5 10W engravers, the people at LONGER are a fantastic place to begin. The beam's size, power, and focal length are the key distinctions between them; nonetheless, they can engrave a significant amount of material.

    If you are looking for a tool to engrave your selected object, then you should choose the model that is most suitable for your needs. Well, worry not, as we are here to tell you about the three basic types of laser engraving, their differences, and a guide to choose which one suits you according to your need. Without further ado, let's dive right in.

    What Is Laser Power?

    Before we learn about the three types of laser powers, let's just investigate what laser power is. The strength of the laser is what determines how much energy is taken up by the worksheet. The basic rule is that when the laser power is increased, the bend angle grows as well, reaches a peak, and then begins to fall again as the laser power is increased even further.

    The higher the laser power, the more heat is absorbed, which results in a higher peak temperature and, therefore, a more incredible amount of plastic deformation at the scanned surface. This causes the bend angle to increase. After reaching its maximum, the bend angle begins to fall because of an increase in laser power.

    This is primarily the result of two factors. First, the melting takes place in the region that is being irradiated at higher power, and the heat energy that is being applied is used up in the phase transformation rather than in the bending of the material. Second, when the power is increased, the peak temperature of the surface of the bottom of the vessel likewise increases.

    This results in a reduction in the difference between the plastic deformation at the top surface and the bottom surface, which in turn leads to a reduction in the bend angle at greater power.

    In terms of optical laser power, the vast majority of the most popular laser engravers on the market now fit into only two primary categories, namely the 5W and 10W optical power. The modules in the first category each contain a single laser diode. In contrast, the 10W modules contain ingenious optics that combine laser light from two different laser diode sources, resulting in output power that is twice as strong as that of the lower-powered modules.

    What Exactly Does The "W" Stand For?

    Wattage is one of the most significant aspects to consider when discussing laser cutters. It is something that you will need to specify when you first purchase the machine, and it is the factor that affects the final cutting power and speed of your project.

    When the wattage rating is increased, the flow of energy also increases. When it comes to laser cutters, having a 20W laser rather than a 5W laser will enable energy to transfer at a substantially faster rate.

    You can see a sequence of lasers inside the head of a LONGER RAY 5 if you crack it apart and look at the laser inside of it. However, we strongly advise against doing this. The head of the 20W laser is made up of four 5W lasers, all of which are pointed in the same direction and concentrated through the head of the laser.

    Why? The purpose of this is to generate more power and more energy from a single laser beam.

    Differences Between LONGER RAY 5  5W Vs. 10W Vs. 20W

    The 5W, 10W, and 20W LONGER RAY 5 all share quite a few characteristics in common with one another. On the other hand, there are a comparable number of differences. Let's focus on what differentiates these machines in a series of head-to-head comparisons so that you can make the most informed decision possible about which one to purchase.

    Power Of The Laser Head

    Before we go any further, there is something that needs to be clarified: although the laser head is the only difference between the two, it has a significant impact on the operation of your LONGER RAY 5 laser engraver, and we will go over those differences in depth here.

    Regardless of which wattage option you go with, the LONGER RAY 5 will provide you with the same framework, sensors, and attachments to use. The laser head is the only component that is different.

    The LONGER RAY 5 staff refers to it as a "plug-and-play module" in their explanation. You only need two cables and ten minutes of your time to upgrade from a 5W or 10W laser cutter to a 20W model, which gives you more cutting power.

    Variations in Laser Power Depend on Which Laser Head You Use and the Different Materials You Can Cut. You can improve the power of your 5W or 10W laser by purchasing a 20W module to add to it.

    To put it another way, if you want a 20W, you have the option of either purchasing one specifically designed for that purpose. The only choice available to you if you want a 5W or 10W is to purchase the machine in its current state.

    The benefits are significant even though the adjustment is rather straightforward. The next sections are all about the difference that the simple head swap makes.

    Quickness Of Project Completion

    The exact amount of time it will take to finish the project is contingent on a few different factors:

    • Quickness of the route
    • Precision in cutting depth, selection of materials, and complexity in design.
    • The depth of the etching or cut.

    The remaining three of these five parameters are not dependent on your laser cutter in any way. The speed with which your laser cutter completes your job is solely dependent on the routing speed and cutting speed settings.

    In this competition, the speeds of the various routes do not differ from one another. The routing speed of the 5W, 10W, and 20W is all 10000mm/min, which is far quicker than the previous generations.

    Where do we stand with the cutting depth now? Here is where you'll see a significant deviation from the norm. A laser with 10W of power can cut nearly exactly twice as deep as a laser with 5W of power. When compared to the 10W, the 20W has twice the cutting depth.

    This indicates that there is a theoretical difference in cutting depth that is equivalent to four times greater when going from 5W to 20W.

    LONGER RAY 5 states that the difference might be very different depending on the material that is used:

    When it comes to the amount of time, it will take to accomplish a project. A 20W laser cutter will get the job done the quickest, followed by a 10W laser cutter, and finally, a 5W RAY laser cutter will be the slowest.

    Space For Making Cuts and Working Area LONGER RAY 5

    While the chassis of each LONGER RAY 5 is the same, the cutting areas of the various configurations are also quite comparable. The LONGER RAY 5  5W and the LONGER RAY 5 10W lasers offer precisely the same cutting area, measuring 400x400mm (15.75×15.75inch).

    Although the laser head on the 20W is significantly larger than that found on the 10W, the cutting area is marginally reduced. The cutting area for a 20-watt laser is 375×375mm (14.76×14.76 inch).

    Although the difference isn't huge, it's nevertheless significant enough to indicate that the 5W and 10W laser cutters have a little advantage in this category.

    Alternatives To Materials(Cutting Capability)

    One further aspect of the topic that is connected to laser power is the many kinds of materials that can be worked with. While attempting to engrave or cut certain materials, significantly greater force and forcefulness are required.

    You can work with a greater selection of materials when you have a 20W. You can also work with more substantial materials, which opens even more possibilities for the kinds of projects you can develop.

    The Ray5 20W comes equipped with a powerful laser module with a 20W output. Also, this machine features the most recent generation of laser enhancement technology, which increases its capacity for cutting. It can cut through 0.002 inches (0.05 mm) of stainless steel, as well as 0.59 inches (15 mm) of pine wood and 0.31 inches (8 mm) of acrylic in a single pass.

    Because of recent advancements in compressed laser technology, the laser spot may now be as small as 0.08*0.1mm2, making it possible to engrave artwork with thinner lines, clearer texture, and more attractive details. And the air-assisted interface is reserved, which allows for a wide variety of air pumps to be easily matched up with more hygienic surfaces.

    While utilizing the 5W cutter, metal, ceramic, and stone become a great deal more challenging to work with, and in all honesty, the 5W power setting is more commonly used for engraving than it is for cutting. When utilizing a 5W or 10W laser cutter, most people adhere to cutting materials made of All Wood, Paper, Plastic, Leather, PCB Board, Aluminum Oxide, Non-Reflective Plating, And Lacquered Metal.

    Think about getting the 20W laser if you wish to work with a variety of various types of materials. For the purposes of our projects, we have successfully cut through even the denser woodlands.

    Precision

    What should you do if you need to draw lines on a component that are extremely thin and accurate? In this scenario, we strongly advise you to avoid using the 20W laser head, even though the risk is still relatively low.

    The spot size of the 20W laser is 0.08×0.10mm. Imagine that the laser spot is the point at which a laser pointer is pointed. If the RAY uses this laser pointer to cut, you will want the tip to be as small as it possibly can be.

    The laser spots of the 5W are 0.08×0.08mm, and the 10W are 0.06×0.06mm lasers. The laser spot of the 20W laser is significantly larger.

    So, if you require an accurate component, you should stick to either the 5W or the 10W.

    Different Engraving Capability

    Pieces can also be engraved with this type of laser cutter, which is another useful function of these machines. A small amount of material is removed from the top surface to produce designs via engraving. Because engraving does not go as deep as cutting, the power required is not as significant.

    The 5W RAY's capacity to engrave is significantly improved thanks to a smaller laser point and higher precision than its predecessor. Because the component only needs one pass with the laser, and the routing speed is the same across the board for these three possibilities, the 5W is the one that should be chosen.

    If you need to engrave and cut the same object, going with the 10W laser might be the best choice for you. It possesses an excellent equilibrium of slicing force and accuracy.

    Make Colourful Creations

    The ability to generate colorful engravings on metal is a special capability that is exclusive to the 20W LONGER RAY 5 and cannot be found on any other machine. What is the mechanism behind this? Because of the increased power provided by the 20W laser, it is capable of oxidizing metal at a variety of rates. It's hard to believe when you see it in person.

    Altering the laser's power causes the metal's oxidation to occur at varying rates, ultimately producing a variety of colors. It is effective on brass, copper, stainless steel, and titanium in addition to aluminum. The only difference is the range of colors that are available to you (which depends on the metal type).

    Lasers with 5W and 10W outputs are not powerful enough to accomplish this task. You'll need the 20W model if you wish to create vivid engravings on metal.

    Pricing LONGER RAY 5 Laser, Available In 5W, 10W, And 20W.

    What should I expect to pay for this? The distinction is not as bizarre as it may initially appear to be:

    • LONGER RAY 5W: $299.99
    • LONGER RAY 10W: $449.99
    • LONGER RAY 20W: $899.99

    These are currently on discount. Hence it's high time to make a purchase.

    What Different Material Can Different Laser Power Cut Or Engrave?

    Cutting using a laser can be done on a wide variety of materials, including but not limited to wood, paper, plastics, glass, leather, foam, textiles, and metals. By selecting the parameters that are most suitable for the laser, one can ensure that the cuts produced are of high quality and have a smooth surface finish. On the other hand, it is not suggested to use a laser cutter for cutting certain materials, such as vinyl or ABS.

    To produce the desired cut, a laser cutter operates by concentrating a high-energy laser beam on the surface of the substance it is cutting. This causes the material to burn and evaporate.

    When being worked on by a laser, each material exhibits its own unique characteristics and necessitates a unique configuration of the various laser parameters to achieve a clean cut with a high level of surface finish.

    Aside from that, the capacity of a laser to cut through the material is determined by the sort of laser that is being employed.

    In general, laser cutting works best with natural materials like wood, paper, leather, and metals, among other things, because these materials produce no or only a limited amount of potentially dangerous by-products.

    Final Takeaway

    The best possible outcome will be achieved with a laser power that is tailored specifically to the constituent material. For example, engraving paper uses significantly less power than engraving wood does on average. A minimal amount of power is required to achieve an engraving that is uniformly homogenous in acrylic and is not very deep. In addition, having a higher power enables speedier work while processing engraving materials.

    The software allows for straightforward control of the laser's output power. Nonetheless, the hardware has a role in determining the maximum power. The following criteria must be met: You are able to process a wide variety of materials with a laser machine that has a high laser power, which provides you with a great deal of freedom.

    How to Make Perfect 3D Objects Using FDM 3D Printer - LONGER
    How to Make Perfect 3D Objects Using FDM 3D Printer

    3D printing has become quite popular in the last few years to make complex shapes allowing new possibilities in many industries. Significant impacts are seen in industry, medicine, agriculture, and many other fields. According to results from research, up to 98.81% accuracy is achieved with commercial FDM printers. Is it easy to achieve an outstanding quality such as this?

    Many factors can help you achieve high quality and an accuracy of almost 99% through the tips and tricks mentioned in this article. Without further delays, let’s hope on!

    Choosing the Right Material

    The suitable material is a defining quality and expense for the model you need. You can choose any material, but assessing the design’s purpose will save you time and money. Explore all possible options and experiment a little to enhance your capability.

    PLA – Polylactic Acid is one of the most common materials for FDM 3D printing because of its rigidity and brittleness. Use it for ornamental models or if you want to learn more about 3D printing as a starter, as it is easier to build.

    ABS – Acrylonitrile Butadiene Styrene, stronger but challenging to build, ideal for functional parts. So, choose it as such because it is inflexible.

    PETG – Polyethylene Terephthalate is stronger than PLA and more flexible than ABS. Perfect for outdoor models as it has good chemical resistance.

    Nylon – Strongest and most flexible, suitable for tools and functional parts because it is durable.

    Take Care of Filaments

    Store your filament spools properly and keep them wound at all times. Any careless knots or breaks can cause clogging in the extruder and damage in printing.

    Consider storage space if you keep a few spools for backup and free of humidity. You don’t want your feed to go stale so keep absorbents or air jar containers. We also recommend using Filament Filters to keep your spools clean and oiled.

    Split Your Models

    The best complexity is the simplest. You can save tons of time and cost if you work on that. Splitting your model into two or more parts can save much material on supports and be made individually. After you are done with parts, you can join them together quickly afterward.

     How to Make Perfect 3D Objects Using LONGER FDM 3D Printer - LONGER 3D

    Paying Attention to Detailing is Paramount

    Depending on the size of your FDM printer and the material used, your design will always have limitations. You should not reduce the thickness of the model’s walls to less than 1mm, making it safer for FDM printed designs. The more complex the shape, the more safety cushion you require. Furthermore, you need more space between interlocking parts. Anything higher than 0.4mm is considered safe.

    Strong Models Require Stress Distribution and Analysis

    Take a look at the image below. The one on the left is more prone to failure if force is applied to either end. The model on the right has a brace to support both legs of the angle, supporting it. Most slicer and 3D designers in the market allow you to analyze your model based on different preferences. Learn to use them and fix errors in your 3D models as they come along.

     How to Make Perfect 3D Objects Using FDM 3D Printer - LONGER 3D 2

    Orientations of Holes in Your Models

    As we discussed above regarding splitting the model and allowing bracing, managing holes orientation is also essential. The model on the left requires support as the top arm can bend under the weight. Your printer can easily print the hole on the right with a vertical axis orientation. A simple rotation does the trick.

     How to Make Perfect 3D Objects Using FDM 3D Printer - LONGER 3D 3

    Now, if you have multiple holes in different directions and orientations, here is what you should do. Prioritize the blind holes first. When they are covered, you can prioritize smaller holes, so they don't get smothered under the wait. Lastly, you must consider which hole is more critical to the model design and work from there.

    Managing The File’s Polycount

    Make it easier for your printer when it comes to the polycount of your design. You don’t want a processing nightmare for an intricately designed model. Keep the polycount as low as possible, or split the model to keep the polycount in check.

    Following Guidelines for Working Temperature

    Each filament type and manufacturers have different recommendations for extrusion temperatures. Please follow those suggested temperatures with a buffer of 10 degrees higher or lower. Significant changes can cause lower-quality FDM outputs. You don’t want your model to have wrinkles, spilling, or sticking where not needed.

     How to Make Perfect 3D Objects Using FDM 3D Printer - LONGER 3D 4

    The platform should be heated adequately to allow the print to stick with it and give the printing parts above sturdiness.

    Choosing the Best Printer and Manufacturer

    This is the most critical part. Your tools are what makes or break your design. You should not spend on an expensive machine which isn’t up to the mark. If you are new to 3D printing, why not consider optimal-priced 3D FDM printers?  

    The LK5 Pro FDM printer from Longer has sufficient spacing to allow for larger designs, as it also has an upgraded dual blower kit. You can also choose the LK4 X FDM printer with a direct dual-gear extruder.

    LONGER LK5 Pro

    Talking to the manufacturers or getting recommendations from your friends and others in the field is always the best choice.

    Epoxy Resin Coating for Strength

    The strength of your 3D print is crucial, especially for functional tools. Epoxy resin coating after you are done printing can enhance the strength of your product. The coating adds a hard layer outside your print. It will also help hide all the layers and extrusions left on your surface due to supports and joints.

    Best Practices for FDM 3D Printing

    • Don't let the bridge exceed 5mm as sagging may occur, or your supports can leave a mark in the end
    • You can drill into your vertical hole diameters if you want greater accuracy
    • Add supports if you consider making models with an angle higher than 45 degrees.
    • Include chamfers that are at 45 degrees angle for all the edges of your model that are touching the base/build plate of your FDM printer
    • Considering practices such as splitting model, the orientation of holes, and build direction can significantly influence the final build time and costs
