For the long-term use of laser engraving machine industry, or DIY enthusiasts, there will always be some problems in contact with laser engraving. For different materials, the parameters and methods of laser engraving are also different. So, how to adjust these to achieve the desired effect? This issue brings you ten common questions about laser carving, and provides you with suggestions on different materials and machine use methods.
1. Some carving suggestions on solid wood and hardwood.
When carving hardwood, we suggest to cover the surface of the wood, so as to reduce the penetration of residues into the carving area and make it easy to clean.
Use the sculpt mode from bottom to top. The working mode of the laser head can be changed in the laser software rdwork, which allows you to carve from bottom to top instead of from top to bottom. The advantage of this is that it can reduce the smoke and debris being pulled into the engraving area when the laser head moves.
After carving, use some degumming agent to clean it. Because the gum of hardwood will turn black when burned by high temperature.
2. Can really carve glass? What are the skills?
First of all, not all glass is flat. Although you may think you need to buy more expensive and high-end glass to get better results, it is not the case. We have many customers who use wholesalers' glassware to carve, but the carving effect is also very good.
For carving glass, we give you some suggestions:
a. With a relatively low resolution, you can get a better effect as long as 300dpi.
b. Change the black in the drawing to 80% black, which can improve the carving quality.
c. We found that laying a wet paper towel on the glass can help to dissipate heat and improve the carving quality, but make sure that the paper is free of wrinkles.
d. Use a finger or paper towel to apply a thin layer of soap to the area to be carved, which also helps to dissipate heat.
e. Polish the engraved area with ScotchBrite or similar to remove glass fragments.
3. What should we pay attention to when carving on plywood (plywood) or light wood?
This material is more suitable for cutting than carving, because the texture of plywood may be uneven and there are different adhesive layers inside. When you want to carve on it, the material is very important. Uneven or too much or too little glue will affect the carving effect. Of course, if you find plywood with good quality, the carving effect is still very good, such as woodcut paintings.
