I have access to 6 varying 3D printers at university (I study architecture so we make a lot of 3D models).
They vary in resolution from Replicators and Formlabs up to the ones that cost a fortune to make because they use a powder instead of extrusions.
For those powder ones, what material do they use?
I am building a 3d printer now as well. I will sell filament and other parts (for bitcoin) starting in a few weeks.
Awesome! Let me know when you get all set up, and what you're capable of printing.
