Subtractive manufacturing vs Additive manufacturing – How to select
Subtractive manufacturing (computer numerical control, or CNC machining) Essentially involves subtracting or cutting from a block of material to create an end product. With many different forms (milling, turning, laser cutting, wire EDM, and carving) and Substractive manufacturing is used for a wide variety of prototyping, production and assembly line applications.
Additive manufacturing (3D printing or rapid prototyping) is a newer fabrication process, with its speed, flexibility and cost advantages. nowaday, 3D printing has become commonplace. Antithetical to subtractive manufacturing, AM deposits materials only where it is necessary on the build platform and typically does so layer-by-layer. AM comes in many different technology forms (FFF, SLA, DLP, MJF, etc.) and is capable of printing a plethora of polymer and metal materials.
Both technologies have their strengths and weaknesses when it comes to a product development and the manufacturing environment.
