Acrylic (PMMA) CNC Machining
Machined acrylic is a rigid, translucent thermoplastic that offers UV stability
Machined acrylic, or PMMA, parts exhibit good optical properties, UV stability, high gloss, and scratch resistance. It's an economical alternative to polycarbonate when impact strength and overall toughness is not needed and can be used as a shatterproof alternative to glass.

Uses for Acrylic Parts
The clarity of acrylic makes it a good choice for optical and lighting applications. It can also be a shatterproof alternative to glass.
- Light pipes
- Light shades
