Hello everybody, I am new to this and need some general informations. What is the max size of an object printed by Shapeways. What is the most resistant material, regardless to the look of it. And what is the weight of 1 cubic cm of this material. I need to print a couple of parts, around 20 cm size: a wheel and a base that will support this wheel, connected with a common ball bearing ring. Thank you in advance, guys!
