Why 3D Printing Can’t Replace Traditional Metal Fabrication for Prototyping
3D printing is becoming increasingly popular and uses a process called additive manufacturing, which “uses data computer-aided-design (CAD) software or 3D object scanners to direct hardware to deposit material, layer upon layer, in precise geometric shapes,” (GE.com). This is in contrast with traditional sheet metal fabrication, which uses machining, laser cutting, punching, and other processes…
