Polymethyl methacrylate (PMMA) is also known as acrylic or acrylic glass. It is a transparent, ultraviolet (UV) light, and scratch-resistant, lightweight, rigid thermoplastic material with an excellent optical transmission.
The growing use of PMMA in medical device and display manufacturing demands a high-precision micro-machining process to create fine features.
In our application lab, we have seen that our Onefive ORIGAMI XP femtosecond laser is well suited to machine PMMA films. Using infrared wavelengths to process PMMA films yields much better quality than a long-pulse laser CO2 laser. Read more about what we did.
