First you have to create a 3D digital model of whatever it is you want to print. The good thing is you don’t need a special computer to do this and there is plenty of free software available to help you do this. Then you upload your 3D model to 1click3dprint.com and let us take care of the rest. The 3D printing process turns a digital object into tiny slices (cross-sections), then lays down each slice, sticking each slice together until it makes a physical object. These slices can be pretty complicated, and some 3D printers can make things with moving parts like cranks and hinges.
