* '''PVC (Poly Vinyl Chloride):''' Also known as '''"vinyl"''' '''"pleather"''' or '''"artificial leather."''' Most adhesive vinyl shelf paper (e.g. Con-Tact Paper) also is PVC. Emits HCl and nasty chlorinated compounds when cut! Don't ever cut this material as it will ruin the optics, cause the metal of the machine to corrode, and ruin the motion control system. | * '''PVC (Poly Vinyl Chloride):''' Also known as '''"vinyl"''' '''"pleather"''' or '''"artificial leather."'''

* '''Polycarbonate:''' Also known as '''"Lexan."''' Polycarbonate is also often found as flat, sheet material. The case cover window on the laser cutter is made of Polycarbonate because polycarbonate strongly absorbs infrared radiation! This is the frequency of light the laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Polycarbonate can also emit flame and chlorine gas when cut, making it a poor choice for laser cutting. | * '''Polycarbonate:''' Also known as '''"Lexan."'''
