FAQs

Q: What is the difference between raster and vector laser cutting?
A: Raster cutting involves moving the laser beam across the material, while vector cutting follows a defined path. Vector cutting is more precise and suitable for intricate designs.

Q: How do I prepare a 3D model for laser cutting?
A: Flatten the 3D model into a 2D design, consider material thickness, and optimize the cut paths for efficiency.

Q: Can I use any type of laser cutter to cut 3D models?
A: Most CO2 and fiber lasers are suitable for laser cutting 3D models, but the specific capabilities vary depending on the laser type and power.
