Printing:The printing process depends on the type of 3D printing technology:fused deposition modeling (FDM) melts a plastic filament, stereolithography (SLA) cures liquid resin, and selective
PMMA is a common choice in lenses. It has relatively poor thermal resistance. PMMI and PC resist heat better and are used on more powerful light sources. The housings of car headlights are primarily made of PC, protected with silicate lacquer for improved UV resistance. Poor chemical resistance is another disadvantage of PC.
