Novel Multi-Beam Processing System for Laser Additive Manufacturing

By Rahul Patwa, Hans Herfurth and Jyoti Mazumder

Additive manufacturing (AM) processes (also commonly referred to as 3D printing) allows the layer-by-layer build-up of parts rather than through molding or subtractive techniques such as machining. The idea that AM machines can print 3D objects much the same way that inkjet printer creates 2D images on paper is being described as “the next industrial revolution”1. Currently there are a number of AM processes that use a variety of materials (plastic, metal, ceramics) in different forms (powders, liquids, wire or sheets) with different heating sources.
