We compared the main FDM 3D printing plastics – PLA, ABS, TPU (Flexible), PC and PA(Nylon) – by material properties and find the best option for your application.
PLA – Rigid and actually quite strong, but is very brittle.
ABS – ABS is usually picked over PLA when higher temperature resistance and higher toughness is required.
TPU – Mostly used for flexible applications, but its very high impact resistance can open for other applications.
PC – PC is the strongest material of all, can be an interesting alternative to ABS as the properties are quite similar.
PA – PA possesses great mechanical properties, and in particular, the best impact resistance for non-flexible filament.
