5.4 Acrylic

・Identifying Acrylic
Acrylic is also known as PMMA or plexiglass, the scientific name is polymethyl methacrylate. It is one of the few plastics that can be processed by laser.

Before processing, it is important to distinguish whether i t is acrylic or other transparent plastic
materials (PVC, PC), which are not suitable for laser processing. When processed on, the edges of the acrylic are sharp and clear. If you see yellowish burn marks, the material is not acrylic. However, if
no burn marks are seen, it doesn’t prove that the material is acrylic.

・Scratches On Acrylic
Scratches can be removed with plastic polish.

・How To Clean Cloudy Acrylic
It is recommended that the film should remain on the acrylic when processing, unless engraving
greyscale images. Use an alcohol swab to clean the acrylic, please note that too much may cause other
surface defects.
