Acrylic (PMMA)

A rigid, highly transparent plastic that is the common lightweight alternative to glass.

Example: machined Acrylic (PMMA)

What is it?

A rigid, highly transparent plastic that's the common lightweight alternative to glass.

Key behavior

Excellent optical clarity and scratch resistance, but brittle — can crack rather than flex under a hard impact.

Why choose it

Display cases, light pipes, and clear parts where impact isn't a real risk and cost matters.

Applications

Display windows, light pipes, signage, lenses.

Machining notes

Needs sharp tooling and coolant to avoid heat cracking at the cut edge — clear plastic shows any machining defect clearly.
