Source material: Letter format white Tyvek from evelopespot.com
Goal: calibrate the speed and laser power to cut Tyvek
Snag: does not cut
No matter how slow and no matter how high the power, Tyvek seems totally unaffected by the laser, not a trace of a cut or burn, no darkened spot at all on either side.
If I place a piece of white paper on top of the Tyvek, the paper gets sliced through easily and the Tyvek gets cut but unevenly.
If I blacken the Tyvek with a felt pen it cuts also unevenly (probably because of the uneven darkness).
So I wonder has anyone tried Tyvek and what would be the best solution to laser cut Tyvek with the Emblaser?
Should I use an inkjet printer to "paint" the cut areas black?
Looking forward to reading about your experiences.
