FAQs
1. What materials can be cut with a 3D laser cutter?
Common materials used for laser cutting include wood, acrylic, metal, fabric, and leather.
2. What is the difference between vector and raster laser cutting?
Vector laser cutting follows a defined path, while raster laser cutting scans the material in a grid pattern. Vector cutting is typically used for precision cutting, while raster cutting is used for engraving and creating images.
3. How do I generate toolpaths for 3D laser cutting?
CAD software such as Inkscape or Fusion 360 can be used to generate toolpaths that define the cutting path for the laser cutter.
4. What safety precautions should I take when using a 3D laser cutter?
Wear appropriate safety gear, ensure proper ventilation, and operate the laser cutter in a safe and controlled environment.
