Technology is constantly evolving and thus is reflected in the improvement of printing. As of now, 3D printing has been the talk of the town. The majority of individuals today rely on the advanced technology of this 3D Printing approach.

3D printers have ushered in a new era in the industrial business. They have practically limitless options for the goods they generate. Out of several 3D printing techniques, FDM has taken over the 3D printing industry by storm. What better time to start learning more about FDM than now?

This article will take you through why and how novice users can efficiently operate FDM, put it to use, and enhance their marketing tactics.

What is FDM 3D Printer?

In 1980, FDM (Fused Deposition Modelling) was introduced. As you are aware, a typical printer creates images one line at a time. FDM printers are identical, except that they generate images in three dimensions rather than simply two. One layer of your substance is laid on top of another until you have achieved the masterpiece.

The sector, primarily mass media, portrays 3D printing as a pristine and modern tech capable of replicating complicated products. However, because of this, defining 3D printing is incredibly difficult. In truth, there are different 3D printing technologies, but FDM (fused deposition modeling), the subject of this article, is the most popular.

FDM is a method of additive manufacturing that heats and melts a plastic filament coiled over a spindle roll into liquid. This liquid is then stretched across a surface known as the build platform.

You may have encountered the term FFF (Fused Filament Fabrication). FDM and FFF employ the same technique but depict it in two different ways, often confusing those new to the 3D printing sector. The proprietor of FFF later trademarked the name FDM.

What to Know about the Working of FDM 3D Printers?

What material is utilized to execute FDM? All you need is thermoplastic, renowned for being pliable when heated. This feature allows each layer to adhere to the others during the creation process. With so many different types of thermoplastic available, you may choose one that meets your preferences.

To keep the material from spilling over, you must add stability, which is entirely dependent upon the size and shape of the piece. The fascinating part is that FDM can also generate these supports. You may also lift your game by adding water-soluble support materials to hold your design intact.

Reasons FDM 3D Printer Is the Best for Beginners

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.

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.

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.

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.

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.

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

There's been a vast technological development, especially if we talk about 3D printing. We use 3D printing almost everywhere. Whether it is for creating engaging business models or construction models, a 3D printer is always the best choice.

Among the leading 3D printer technologies, FDM is very popular. The reason behind the popularity of the FDM printer is that it is not only highly efficient but also ideal for beginners.

Want to know more about FDM printers? You’ve landed in the right place! In this article, we'll provide you with the ultimate guideline for FDM 3D printers and their applications.

 A Pen Plotter is a Drawing Machine that is positioned between a 3D printer and a Laser Engraver, since it has characteristics of both of them. In fact, it uses a three-axis Cartesian XYZ system (like a 3D printer) to make 2D images (like a Laser Engraver) using a pen. In simple words, this machine allows you to draw as you do by hand, but with the precision and handwriting of a computer.

This guide allows you to make a Pen Plotter using any Longer FDM 3D printer as a base. The change does not alter printing capabilities but is an added feature. Note that this guide is not compatible with printers equipped with BL-TOUCH leveling sensors.

Preparation of the machine

1. Download and print this pen holder:

https://drive.google.com/file/d/1gwQJZo7U1t-0NzUbUzdNdexHfIp1fW4g/view?usp=sharing 

2. Screwdown the two screws placed to the left of the head module and the pen support (the dual blower module already provides two holes where to install the pen support)

3. Proceed to normal leveling of the printer, using the sheet of paper to level the nozzle and the glass of the hotbed
4. After leveling the print bed, remove the glass and replace it with a sheet of paper; Since the sheet of paper is thinner than the glass, the nozzle will be very far from the sheet of paper, but this is normal
5. Insert a pen inside the pen holder; the pen must be in contact with the sheet of paper, the tip of the pen must touch the paper to be able to write, then secure the pen using a screw through the support

6. Using a test sheet, test whether moving the x-axis can write to all points on the sheet
7. To prevent the filament sensor from reporting an error, insert a piece of filament through the filament sensor; also, disconnect the extruder motor E cable

Preparation of the Cura software

1. From the Cura menu, add a new printer that matches your printer model (if LK4PRO add LK4PRO, if LK5PRO add LK5PRO, etc.), and rename the new printer as "Drawing Machine"

2. Replace the Start G-code with this new Start G-code:

; LONGER Start G-code

G21 ; metric values

G90 ; absolute positioning

M82 ; Set Extruder to Absolute Mode

M107 ; start with the fan off

G92 E0 ; Reset Extruder

G28 ; Home all axes

G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed

3. Download and import into Cura this print profile "plotter.curaprofile" for "Drawing Machine". The imported profile allows the printer to work without heating hotend/hotbed and without extruding filament:

https://drive.google.com/file/d/1cxeTZ1QrjHt8bsGC8TLVEHthtU_jNLkI/view?usp=sharing

Preparation of the Drawing File

1. After choosing a 2D image without background (like this one above in the figure), open the "3D Builder" software preinstalled in Windows 10 (if it was not present, download it from the Windows Store). Then select "Open – Load image" to import the selected image.

2. Once the image has been imported into 3D Builder, you can change some settings such as Levels, Smooth, and so on; using these settings, edit the file according to your preferences. Once the editing is complete, select Import Image to get the image converted to 3D file.

3. At this point, assign to the 3D model aheight "Z" of 0.1 mm; in fact, a drawing can be considered as a 3D model composed of a single layer, therefore assigning a thickness of 0.1 mm then the printer finishes the work after the first layer
4. When the 3D model is ready, proceed to export, selecting "Save as - . STL".

Drawing printing procedure

1. Import the previously created "3D" drawing into Cura
2. At this point, the design can be made either full or with only the outline   a.To make a full drawing, make sure "Top/Bottom Thickness" is set to "1"

          b.To create a blank drawing, with edges only, make sure "Top/Bottom        Thickness" is set to "0"

3. Export the Gcode, proceed to print, and here is the final result

4. Download here some sample model, enjoy your new Longer Drawing Machine!

All FDM 3D printers are equipped with some fans, each of which performs a different function. For example, one fan cools the mainboard, another fan cools the hotend, and so on.

A fan with relevant functionality is the cooling fan of the printed filament, which is a fan that cools the print, so as to allow the filament to solidify quickly, avoiding deformation in the print due to heat. This fan can not do anything on its own, and in fact it is always associated with a "fanduct", or a duct through which the air emitted by the fan passes, which is concentrated and directed correctly on the print.

Fanducts come in various shapes and sizes, while all maintaining the same function; depending on its design, the fanduct can concentrate more or less air, in one or more directions. Here's a list of official Longer 3D fanducts, each with different features for different purposes:

• Classic Fanduct

This fanduct is the default model of Longer 3D printers, it allows you to concentrate a large amount of air and cool a large portion of the print at the same time thanks to its round output. It is perfect for prints with large surfaces, prints that are printed at high speed and for prints made with very large nozzles.

• Squared fanduct

This Longer 3D fanduct is equipped with two rectangular outputs, thus being able to divide the air flow equally in two directions. Depending on the printing direction, this fanduct usually takes care of cooling both the part already printed and the part that is about to be printed; In addition, all the air is concentrated in these two zones, so the cooling inflow is considerable. The disadvantage is that for high-speed prints, the fanduct may not have enough time to cool the print because its airflow is very direct.

• Precision fanduct

This Longer 3D fanduct is the one that concentrates the air the most, and then directs it at high pressure and speed at a single point. In fact, due to the great difference in section between inlet and outlet, the air accumulates a great speed at the outlet, thus being able to cool the affected printing part in a few moments. Its main use is for prints with many detailed parts and very thin parts that extend upwards; For example, trying to print a tip, usually the heat causes a deformation due to the collapse of the structure, instead with this fanduct it is possible to dissipate heat quickly, largely solving the problem.

In physics, the propagation in space of electromagnetic field energy is called electromagnetic radiation. Depending on the wavelength, the radiation takes on a different nomenclature; in particular, electromagnetic radiation with a wavelength between about 400 nm and 700 nm is called visible radiation and is perceptible by the human eye and transformed by the brain into visual sensations; this radiation is what is commonly called light.

Frequency and wavelength are inversely proportional quantities, i.e., when the wavelength decreases, then the frequency increases. Radio waves, also used for FM and TV broadcasts, are in the MHz range; instead, microwaves are on the order of GHz. Instead, visible light is already in the order of THz and then increases more and more in the rays due to nuclear decay, which, however, have a minuscule wavelength. Note that with the same power, electromagnetic radiation is able to pass through matter more easily when it has a longer wavelength (i.e., lower frequency); a trivial example is the ability of radio waves to pass through the walls of a house, while sunlight is shielded.

By analyzing the laser beams, they therefore take on a different color according to the wavelength; a blue beam (like the Longer Ray5 laser) has a wavelength of 450 nm, while green or red laser beams have different lengths. However, a laser beam does not necessarily belong to the visible spectrum, as it can also be generated as a different radiation. For example, there are some lasers belonging to the infrared, which are invisible but retain their abilities.

An example of an infrared laser is the CO₂ laser, which is a laser characterized by a wavelength between 940 nm and 1060 nm, which is generated within an active laser medium contained in an air- or water-cooled gas discharge tube. The gas contained within the laser tube consists mainly of carbon dioxide (CO2) and other gases, where an initial gas is excited by electric current but is not able to release a photon because of its chemical structure and then transfers its energy to a CO2 molecule that triggers the first photon. The operation is similar to a neon/fluorescent bulb, although in this case the photons generate a laser beam instead of optically isotropic light.

Given the high power obtainable (as the ratio between input and output power is very high), CO₂ lasers are widely used for metal engraving, for cutting materials, and for industrial welding. They are also very useful in surgery because the main constituent, water, of the cells absorbs very well the emitted infrared frequency. In addition, CO₂ lasers are also used for telemetry, as infrared can pass through the Earth's atmosphere easily, being almost completely transparent to infrared.

Many owners of Longer 3D printers love to customize the machine with additional accessories, LED lighting, and so on. However, each accessory works at a specific electrical voltage and requires a certain current, so attention should be paid to the technical specifications of each of them; in fact, Longer printers generally work at 24V, so it is not enough to simply connect the accessories to the mainboard of the printer or to its power supply, since this could compromise the operation of both the printer and the accessories.

NOTE: This guide is only for an electronically savvy audience! Misinterpretations could cause accidents and damage to equipment. If you don't feel confident, don't try the changes but talk to an expert.

In order to lower the voltage from 24V to a lower one it is necessary to cause a "Potential Difference Drop". The most basic method in physics to achieve this is the use of a resistor, however it dissipates all the current absorbed in the form of heat, so it is an inefficient and unstable method, since it depends on many factors. Nowadays there are various electronic components that can perform this function in an excellent way, and given their really low cost it is really worth considering to be able to operate safely. Here is a description of the best components on the market.

XH-M401

This voltage converter allows you to adjust the potential difference downwards efficiently and supports a high current passage thanks to the presence of two power mosfets. Connected to one of the outputs of the printer's power supply, it allows you to adjust the voltage between 24V ~1V, so it is ideal for connecting 12V & 5V LED lamps that require high current absorption, to connect 12V & 5V fans, to connect camcorders that require a specific voltage, or any other type of accessory.

L7812

This linear voltage regulator allows you to adjust a voltage of 35V max in a voltage of 12V output, however the output current is 1A max and also dissipates in the form of heat; for this reason, the voltage regulator has a hole, as it must be fixed with a screw on top of an aluminum bracket in order to reduce its temperature. Using this regulator, it is possible to reduce the voltage from 24V to 12V, however its use is limited to accessories that require a very low current (for example, a 12V fan), and in any case the regulator must be dissipated by fixing it to the printer frame taking care not to cause short circuits.

L7805

This linear voltage regulator, similar to the L7812 regulator, allows you to reduce the voltage by having a 5V output. It is often used to reduce voltages of 12V towards 5V, however it can also be used to reduce the 24V of the machine in 5V even if the dissipation in the form of heat will be really excessive. It is strongly discouraged to use this voltage regulator allows, preferring in its place the XH-M401 regulator.

SZBK07 300W/20A (for special applications)

This voltage converter can be too elaborate, as it allows both to adjust the output voltage and to limit the max current absorbed by the connected component in output. This turns out to be the best compromise to power driver-free LEDs, battery charging and other applications that require special attention. It is exposed here only for information, as accessories for 3D printers do not require such precautions.

This Printer started out on Kickstarter in 2019 and was successfully funded there. The vat has been updated by Longer since it was released and is a plastic one compared to the metal one originally.

So its a 2K LCD screen at 2560 X 1440 resolutions and 47.25µm pixel size, the build plate is 120mm(L)*68mm(W)*170mm(H); With a solid linear guide and special slider design, it will ensure the accuracy and stable of Z-axis.

So I set about unboxing the printer live over at my Twitch channel, it comes well packed in a box with lots of protection for it, one of the first things I noticed about this resin printer is that you need to assemble the UV cover as it is flat picked and has a paper covering both sides of it to protect from scratches.

Assembling the UV cover took the longest to do as the paper that needed taking off was stuck well to the plastic. Once this was done it was a little tricky getting the elastic bands on it to hold it together, but if you don’t wish to use the elastic bands that come with the printer you can find STL files for a system to hold it together a bit better, as I always feel it's going to fall apart in my hands when moving the lid about.

Putting the vat on is straightforward as always and it was a quick process to level the build plate.

Once I've done everything I put the USB drive into the printer and see that there were 4 test files, so I set about printing them all, they all came out fantastic as I would expect from a resin printer, the touch screen is responsive and nicely laid out and easy to navigate it.

I set about slicing some of my own files I wanted to print on it and if you want you can use Longer 3D own slicer for it, but I use Lychee Slicer as my go-to slicer these days. It was easy to add the printer to the slicer, you just need to make sure you save the file to the USB drive as a .lgs30 file for the printer to read it.

Ok so it’s not the biggest of build plates for a resin printer, but don’t let that fool you. I found this printer was able to print everything I was slicing for it, I had one failure out of about 30 prints and that was down to human error as I didn’t add supports correctly. The print quality is good especially for a 2k resin printer, it wasn’t overly loud when it was printing and I didn’t notice any bad smells of resin coming from it, which I do use an air purifier next to all my resin printers just for some added protection.

So who is this resin printer aimed at? That’s a good question, I think that this might just be one of the best entry-level resin printers that you can buy at the moment, resin printing can be expensive if you are starting out in it, printer, wash and cure station, IPA for the wash and gloves, etc, it starts adding up. So if you purchased this as your first resin printer and you found out that resin printing wasn’t for you, it's not a big amount of money spent on the Orange 30 and I’m sure you will find a buyer for it if you put it up for sale.

If you are an experienced resin user already you might possibly have bigger resin printers that you use, like myself, recently I was printing a Wicked3D STL which was a decent size, and I used 3 resin printers to print all the parts for it and the Orange 30 fitted perfectly for printing the small parts for it, in-between my bigger resin printers, some people use resin printers for small tabletop figures and I’m sure you would be able to get a good amount of them on the build plate of the Orange 30.

So in conclusion I think that this resin printer is ideal for all users, especially for the price. I have been printing litho on this printer too and the photo quality is good. if you were to invest in this I think most people would be pleased with the results of the prints.
