What is Acrylic or PMMA?

Acrylic, or polymethyl methacrylate (PMMA), is a highly adaptable plastic material commonly used in CNC machining due to its outstanding qualities. Known for its transparency, excellent light transmission, and resistance to UV light, acrylic is a preferred material for various applications, such as signage, displays, lenses, and lighting.

With its superior optical properties, ease of machining, and flexibility, acrylic is an ideal option for CNC projects that demand both precision and visual appeal.
