We are printing with PLA, because it is currently the most able filament to use for fun prototyping. We have nylon and ABS, but they are a bit less forgiving and more caustic to heat. PLA creates a rigid object with minimal expansion. The printer we are using has dual extruders, but we are only using one. We have a heated aluminum plate with painters tape over it. The x,y, and z axis are controlled by small stepper motors and an Adruino computer. So much fun. If could print anything, what would you print?
