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.

Common applications:

  • Light pipes
  • Lenses
  • Light shades
  • Optical fibers
  • Signs
