Laser engraving is a technology that utilizes a high-energy laser beam to process materials. Compared to traditional mechanical engraving, laser engraving has the advantages of high precision, speed, and no contact. Lasers equipped with 3D galvanometers can realize many high-precision and complex tasks. High-precision 3D galvanometers can control the position and focus of the laser beam, making it possible to perform fine material additions at multiple levels to create complex three-dimensional objects. This article will explore the principles and advantages of laser 3D engraving of wood and its applications.

Principles of laser 3D engraving of wood

Laser engraving uses a high-energy laser beam to focus on the surface of wood, instantly vaporizing or ablating the material through high temperature to form an engraved pattern. Its workflow is as follows:

  1. Design model: use 3D modeling software to design the desired engraving pattern or model.
  2. Generate laser path: Convert the 3D model into a path file that can be recognized by the laser engraving machine.
  3. Set up the machine: Fix the wood on the laser engraving machine and input the path file.
  4. Start engraving: the laser engraving machine controls the laser beam to engrave on the surface of the wood according to the path file instructions.

Control of temperature

In the laser engraving process, the control of temperature is crucial. Too high a temperature may lead to excessive ablation of the wood, affecting the quality of the engraving; while too low a temperature may not be able to engrave effectively. The following are the key points for temperature control:

  1. Laser Power Adjustment: By adjusting the laser power, the energy of the laser beam can be controlled, thus regulating the engraving temperature. Generally speaking, the higher the power, the higher the temperature.
  2. Engraving speed: engraving speed is also an important factor affecting the temperature. The slower the speed, the longer the laser stays on the surface of the wood, the higher the temperature; and vice versa.
  3. Focus Adjustment: The focus position of the laser beam directly affects the concentration of the temperature. By adjusting the focus, the heat distribution of the laser beam can be precisely controlled.
  4. Cooling system: The laser engraving machine is equipped with a cooling system to dissipate heat in real-time through water cooling or air cooling to prevent the wood from overheating.
  5. Ambient temperature monitoring: During the engraving process, the ambient temperature is monitored in real-time to ensure that the operation is carried out within the appropriate temperature range to ensure the engraving effect and avoid damage.

Advantages of laser 3D engraving wood

  1. High precision: laser engraving can reach micron-level precision, and can engrave very detailed patterns and text.
  2. Non-contact processing: laser engraving belongs to non-contact processing, and will not exert mechanical stress on the wood, to avoid material deformation or damage.
  3. Diversified patterns: laser engraving can easily realize complex 3D patterns and structures, applicable to a variety of design needs.
  4. Efficient and quick: laser engraving is fast and suitable for mass production, which improves production efficiency.
  5. Environmental protection and energy saving: the laser engraving process has no wastewater and gas emissions, is in line with environmental requirements, and has low energy consumption.

Application areas

Laser 3D engraving wood applications are very wide, covering a variety of fields:

  1. Furniture manufacturing: laser engraving technology can be used to decorate the surface of furniture, carving out exquisite patterns and patterns to enhance the aesthetics and added value of furniture.
  2. Crafts production: laser engraving is suitable for the production of wooden crafts, such as carving wood carvings, wooden photo frames, wooden ornaments, etc., to achieve high precision and complex patterns of engraving.
  3. Architectural decoration: In the field of architectural decoration, laser engraving can be used for the engraving of wooden wall panels, ceilings, and other decorative materials to increase the decorative effect.
  4. Gift customization: laser engraving technology can be used to customize wooden gifts, such as wooden business cards, wooden souvenirs, etc., to meet personalized needs.
  5. Education and scientific research: laser engraving technology is also used in the field of education and scientific research, and can be used to make teaching models and scientific research experimental devices.

Conclusion

Laser 3D engraving wood technology with its high precision, high efficiency, environmental protection and other advantages, is gradually replacing the traditional wood engraving process, becoming an important means of modern wood processing. With the continuous progress of technology, laser engraving will show its unique charm in more fields, bringing more innovation and development opportunities for the wood processing industry.
