How to Build a 3D Printer

3D Printing Hub

Compared to a regular DC motor, a stepper motor moves in increments or steps, making it more ideal for precise movements. You can’t start on a Cartesian 3D printer and then suddenly decide to switch to a delta 3D printer halfway through the assembly – unless you have the time and money for it, of course. The best way to learn about 3D printing is to build a 3D printer from scratch.
