1.Acrylic (a kind of plexiglass)
Acrylic is especially widely used in the advertising industry. Available in a variety of shapes and sizes, using a laser engraver is relatively inexpensive. Under normal circumstances, plexiglass adopts the back carving method, that is to say, it is carved from the front and viewed from the back, which makes the finished product more three-dimensional. When engraving on the back, please mirror the graphics first, and the engraving speed should be fast and the power should be low. Plexiglass is relatively easy to cut, and an air blowing device should be used when cutting to improve the quality of the cut. When cutting plexiglass over 8mm, large-sized lenses should be replaced.
2. Timber
Wood is easy to engrave and cut with a laser engraver. Light-colored woods like birch, cherry, or maple vaporize well with lasers and are therefore more suitable for engraving. Every kind of wood has its own characteristics, and some are denser, such as hardwood, which requires more laser power when engraving or cutting.
The cutting depth of wood by laser engraving machine is generally not deep. This is because the power of the laser is small. If the cutting speed is slowed down, the wood will burn. For specific operations, you can try to use large-scale lenses and use repeated cutting methods.
3. MDF
It’s the kind of wooden pallets we often use as sign linings. The material is high-density board with thin wood grain on the surface. A laser engraving machine can engrave on this high-end material factory, but the color of the engraved pattern is uneven and black, and generally needs to be colored. Usually you can get better results by learning the proper design and using 0.5mm two-color plates for inlay. After engraving, just use a damp cloth to clean the surface of the MDF.
4.Two-color board:
Two-color board is a kind of engineering plastic specially used for engraving, which is composed of two or more layers of colors. Its size is generally 600*1200mm, and there are also a few brands whose size is 600*900mm. Engraving with a laser engraver will look very good, with great contrast and sharp edges. Pay attention to the speed not to be too slow, do not cut through at one time, but divide it into three or four times, so that the edge of the cut material is smooth and there is no trace of melting. The power should be just right during engraving and should not be too large to avoid melting marks.
