Step 1: Fundamentals and Safety
Laser cutting uses a focused CO2 laser beam to cut or engrave materials like wood, acrylic, and leather by vaporizing or melting them. Key concepts:
- Vector cutting: Thin lines (hairline) for full cuts through material.
- Raster engraving: Fills areas for etching without cutting through.
Safety First (from Xometry guidelines):
- Get proper training.
- Never bypass interlocks.
- Follow manufacturer instructions.
- Keep a logbook.
- Have a fire extinguisher nearby.
- Vacuum regularly.
- Know safe materials (avoid PVC, Teflon).
- Never leave unattended.
- Avoid wooden surfaces under machine.
- Adjust pulse rate to reduce fire risk.
Wear laser safety glasses, respirator, gloves. Ensure ventilation.
