Abstract: 3D Printing technology, also known as Additive Manufacturing (AM), refers to processes used to generate a 3D object in which layers of material are successively formed under a computer controlled program to create a physical object. The 3D file source is usually sliced into several layers, each layer generating a set of computer controlled instructions. Both 3D printing and additive manufacturing reflect that the technologies share the theme of sequential-layer material addition or joining throughout a 3D work. Yet, the technology used by most 3D printers since the 2010’s, especially by hobbyist and consumer-oriented products, is Fused Filament Fabrication (FFF), also known as material extrusion or the proprietary Stratasys denomination’s Fused Deposition Modeling (FDM). FDM was patented in 1989 by S. Scott Crump just before he launched the Stratasys company with his wife, Lisa Crump.
