PLA filament with excellent properties for FDM printers The best of both worlds is the idea behind the newly developed PolyLite PLA PRO filament from Polymaker! The PLA PRO filament combines the properties of both PolyLite PLA and PolyMax PLA. It is not only characterised by excellent impact resistance, better resilience and high rigidity: but it also has the excellent technical properties of normal PLA! This creates silky-smooth surfaces for high-quality 3D prints!
