Introduction to 3D Printing
3D printing is the process of creating a three-dimensional object by adding many layers of material together. This process is performed by a computer controlled machine commonly called a 3D printer. This article will primarily be discussing the Fused Deposition Modeling(FDM) method of 3D printing. Most FDM printers will heat up plastic and push it out from a nozzle. This process is called extruding.
