LONGER offers a range of laser engraving machines with different power levels, from the RAY5 5W to 20W, LaserB1 20W to 40W model. The power level of the laser is directly correlated with the speed of engraving or cutting, allowing users to adjust settings to achieve optimal results for their projects. One of the key features of LONGER laser engraving machines is their compatibility with a wide range of materials, including wood, fabrics, metal, paper, and anodized aluminum. However, it's important to note that materials like PVC should be avoided due to the emission of toxic fumes during engraving. 

On the other hand, the Long Time B1 30W Laser Engraving Machine offers a balanced power output of 30W, sitting between the B1 40W and RAY5 10W models. It's suitable for printing on materials like wood, acrylic, and rubber, offering manufacturers versatility in their applications. With a good compromise between speed and accuracy, this model delivers reliable performance. 

Miniaturization trend

With the continuous development of technology and the gradual reduction of costs, laser engraving technology has begun to develop in the direction of miniaturization. More and more manufacturers have launched small laser engraving machines, making this technology gradually enter the homes and studios of ordinary consumers. These small devices are usually more affordable, smaller in size, and easier to operate, providing new possibilities for personal creative production. The emergence of devices like the Longer Nano portable laser engraving machine exemplifies this trend, offering lightweight, user-friendly tools tailored to personal creative endeavors. The Longer Nano portable laser engraving machine is a lightweight, user-friendly personal creative tool, make it a great choice for beginners entering the world of laser engraving.

Setup and operation

Portable laser engraving machines are generally designed to be simpler and easier to use, making them relatively easy to set up and operate. They often come with simple and intuitive interfaces and operating guides that allow even inexperienced users to get started quickly. Additionally, due to their compact design, portable laser engravers typically require fewer installation and adjustment steps and can be put into use more quickly.

In comparison, traditional desktop models may require more time and skill to set up and adjust. Due to its complex structure and functions, users may need to spend more time learning and becoming familiar with the operating procedures. In addition, since desktop laser engraving machines usually have more functions and parameter setting options, users may need more technical knowledge to adjust and optimize to achieve the desired engraving effect.

Manufacture

In addition to differences in wavelength and application fields, red lasers and blue lasers also differ in the manufacturing and cost of laser devices. Because blue lasers require more complex manufacturing processes and higher quality materials, blue laser devices are generally more expensive to manufacture than red laser devices. This has also resulted in red lasers being more common in some consumer electronics products, such as laser pointers or laser pointers. Red lasers typically use helium-neon gas, dyes, or specific semiconductor materials that produce light with wavelengths between 800 and 1064 nanometers. In contrast, the main laser material of blue laser is gallium nitride (GaN) semiconductor, which can produce light with wavelengths between 445 and 515 nanometers. There are obvious differences in the laser structure between the generation processes of red laser and blue laser. The laser structure of a red laser can be a gas laser, a dye laser, a semiconductor laser or a solid laser, depending on the laser material used. Helium-neon gas laser is one of the earliest red lasers developed, and semiconductor laser is one of the common types of red lasers. In contrast, blue lasers usually adopt a semiconductor laser structure, mainly using semiconductor materials such as gallium nitride (GaN). These different laser structures have an important impact on the performance and application of lasers, such as power output, wavelength stability, and complexity of the preparation process. There are significant differences in the excitation methods of red laser and blue laser generation processes. Red laser can be excited in various ways, including electric shock, beam incidence or chemical reaction. Specifically, helium-neon gas lasers can be excited by electric shock to generate laser light, while dye lasers can be realized by laser beam incidence or chemical reactions. In contrast, blue lasers are typically achieved by electrically or optically injecting semiconductor materials such as gallium nitride. These different excitation methods determine the energy efficiency, stability and complexity of the preparation process of the laser, thereby affecting the performance of red lasers and blue lasers in their respective application fields.
