Is it safe to laser cut PLA?
Laser cutting of PLA can be performed with either a 9.3 or 10.6 micron CO2 laser. Laser cutting of PLA with a CO2 laser creates a clean, smooth edge without discoloration. Laser processing of PLA with a 1.06 micron fiber laser is not recommended as it is not readily absorbed by the material.
Can PTFE be laser cut?

Power
- 30 W can cut 3-4 mm with 1-3 passes before charring begins.
- 40 W cuts 5-6 mm with 1-3 passes.
- 50-60 W will easily cut 10 mm with 1-3 passes and can cut denser woods.

Can I laser cut HDPE?
It tends to melt rather than vaporize, and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid. It also does not engrave well (again, tends to melt). HDPE/milk bottle plastic Catches fire and melts It melts. This is the #1 material that causes laser fires!!!
