Marrying Addititive and Subtractive Manufacturing

This is a huge news for me to see two areas of my expertise (CNC Machining and 3D Printing) coming together. Both of them has their own strengths and limitations. Marrying them together will be a real step forward toward next industrial revolution. One of the well known brand (DMG) in CNC machines manufacturing has showcased the concept at European machine show. We know about few different concepts being used for Metal 3D printing. DMG is using Laser Metal Deposition concept.

Laser Metal Deposition

The process involves a laser beam used to form a melt pool on a metallic substrate, into which powder is fed. The powder melts to form a deposit that is fusion bonded to the substrate. Both the laser and nozzle from which the powder is delivered are manipulated using a computer numerical control system.


CNC Machining

CNC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools. Tools that can be controlled in this manner include lathes, mills, routers, grinders, EDM machine, Laser cutter etc. The CNC in CNC Machining stands for Computer Numerical Control.


 Additive & Subtractive coming together
