The majority of the 3D printing community can be roughly divided into two camps: the PLA and the ABS users. Both materials obviously come with significant advantages, but why should we have to choose? Hot-end developers E3D have just unveiled an exciting third option that combines the best of both filaments. Called Edge filament, it?s a modified PET material that is stronger, stiffer and tougher than ABS, but is also as easy to 3D print as PLA. Edge also forms excellent bonds between layers, and between layers and the printbed.
