At one point, there were only two materials available for 3D printing: PLA and ABS. PLA is safe and easy to use, but is too brittle and has too low of a melting point for some applications. ABS is a bit more ductile and heat resistant, but smells horrific and is made from some seriously nasty, not to mention carcinogenic chemicals. Now, ther's a much wider array of 3D printing materials available for 3D printing, and the list is growing every day.
The beauty of the Series 1 platform is that you don’t have to worry about committing to a material when you own the world’s most versatile extruder. We’ve mentioned in many other places that the G2 extruder can run about 80 different materials through it using the presets we’ve included in our version of Cura alone, and more still if you’re willing to calibrate the material profiles yourself. If you’re new to doing your own 3D prints, this can be a little intimidating. Here’s where to start.
