What should be kept in mind when laser cutting plastic?

For cutting plastic, it’s best to keep the protective coating on to help eliminate some flashback that may happen. Cutting on the vector grid is best to have the heat travel through it. For smaller pieces or thinner plastic, having a mat, such as a Seklema mat from Rowmark, to hold it down helps. Keeping your speed below 20% can help with smoother direction changes such as rounded corners. If flames happen, your frequency can be the first thing to adjust and turn down.
