PMMA for Poly(methyl methacrylate) is a clear plastic acrylic material that can be used as a replacement for glass. PMMA is easier to print than some tough materials but this does not prevent from being very resistant. Its characteristics makes it the perfect material for shatter-proof glass or windows. Use an extruding temperature of 245-255 °C and a heated bed of around 100°C for best results. Find out our range of a top performing pmma filament.
