Before you can 3D print a part you have to design it using CAD software. There are many softwares out there, some of the more popular ones are Solidworks and Rhino. I prefer to use Fusion 360. It has a built in CAM processor for outputting directly to your machine. We can output our designs right into our 3D printer, CNC Machine, or Plasma Cutter for cutting! The processor converts the shapes to a STL file or G-code. Having everything all in the same software makes it easy to streamline your fabrication from design to final product.
