Types of Laser Interactions with Plastics

There are 3 main types of material interactions when hit by the
CO2 laser beam:
• Vaporization
– The material vaporizes into gas residue which is blown out when cut.
This is the cleanest cutting / marking process.
• Melt Sharing
– The material melts into molten droplets which are blown out when cut.
There is typically some melt-back
• Chemical Degradation
– The plastic material chemically degrades typically releasing carbon smoke.
The material chars and has soot residue
