Methods of Additive Manufacturing

Methods of Additive Manufacturing

In a remarkably short period of time, additive manufacturing (AM) has embedded itself into the main-stream consciousness. Often referred to as 3D printing, AM encompasses a range of methods, 3D printing being just one. There is also stereolithography (SLA), selective laser sintering (SLS), fused deposition modeling (FDM), digital light processing (DLP), polyjet matrix modeling, and laminated object manufacturing (LOM), with variations.

All forms of AM follow the same basic premise: a digital model is physically reproduced by the incremental build-up of material (polymer, metal, ceramic, foodstuff, biological mass, etc. - this list is ever increasing) through computer-numerically controlled (CNC) means, using a laser, nozzle, blade, projected UV image, etc. No material is removed, and thus none is wasted. The cost of producing many different objects is no greater than the cost of producing many identical objects - enabling our current historic shift from mass production to mass customization.

AM has been in development since the 1980s. The first patent for SLA was awarded in 1986; SLS was developed here at The University of Texas at Austin in 1986 by student Carl Deckard and his advisor Joseph Beaman. At once, the AM industry is both mature yet still in a nascent stage, and continues to develop rapidly. From 2011 to 2012, the global market for AM products and services increased 28.6%, from $1.7 to 2.2 billion.

This show features a collection of objects generated for a variety of purposes, created by a range of disciplines. They represent some, though not all, of the many AM methods.
