PMMA or polymethyl methacrylate, is a strong, lightweight and transparent thermoplastic. It is commonly known as acrylic. PMMA filament has excellent impact strength that is significantly higher than glass. In addition, it has half the destiny of glass with comparable transparency and UV absorption properties.
There are several important benefits to using PMMA as a 3d printing material. To begin with, it has a high impact resistance which makes it tough and durable. It’s also extremely rigid with very little flexibility. So, if you’re going to need to print an object that will stand up to a certain amount of stress without bending or deforming, then PMMA 3D printer filaments are a strong contender.
