What materials are suitable for CO2 laser engraving?

The CO2 laser engraver is mainly used to process non-metallic materials, including wood, acrylic, leather, plastics, and textiles.Avoid using metal, glass, or materials containing chlorine to prevent damage to equipment or safety hazards.Before use, the parameters need to be tested, and ventilation must be provided. Regular maintenance focuses on cleaning the lenses and inspecting the cooling system.

What materials can be processed by a CO2 laser engraver?

CO2 laser engraving machines mainly use an infrared laser with a 10.6-micron wavelength to react with the surface of a material, and they are most suitable for processing non-metallic materials.If you have wood, acrylic, leather, or other materials, the effect will be very noticeable.However, it is important to note that metals (such as stainless steel or aluminum) have a low absorption rate for CO2 lasers, and forcing them to cut such materials can damage the machine.

A list of commonly used materials.

Natural materials: Wood, bamboo, leather, paper, and other natural materials are used in making the dolls. The carvings have sharp edges, and the natural textures are preserved.

Plastics: Acrylic, ABS, PVC, rubber, etc. Suitable for making signs or customized gifts, but be aware that plastics containing chlorine (such as PVC) may release harmful gases.

3. Textiles and Composites: Canvas, felt, and fiberboard. It is recommended that you adjust the power and speed settings before cutting these materials to avoid burning.

What materials should be avoided?

Although CO2 lasers are extremely versatile, they are not effective against metals, glass, or ceramics, which are highly reflective or hard.For example, to engrave a metal cup, you should choose a fiber laser machine.And plastics containing fluorine or chlorine (such as Teflon) release toxic fumes when heated, so don't try this at home.

Here are a few tips for handling the meat before processing.

- Testing: The sensitivity of different materials to laser light varies with color and thickness. Before beginning a job, the laser is tested on scrap material to determine the optimal power and speed.

Ventilation: When carving plastic or painting, remember to turn on the exhaust fan or wear a protective mask to avoid inhaling harmful fumes.

Maintenance: Clean the lenses and rails after each use. Dust can interfere with the precision of the laser.

How can the life of the equipment be extended?

To ensure that the laser engraver is always in good working condition, it is necessary to carry out regular maintenance.Once a week, the laser tube cooling system is checked, to make sure the water temperature does not exceed 25 degrees centigrade.If you notice that the engravings are getting fainter or less clear, it could be that the lens is dirty or the laser tube is aging, and you can save a lot of money on repairs by replacing the parts in a timely manner.
