Carl R. Deckard, Ph.D, ME, is an American inventor, teacher, and businessman. He is best known for inventing and developing Selective Laser Sintering (SLS), a method of 3D printing.[1]


Deckard initially came up with the idea for SLS as an undergraduate at the University of Texas at Austin (UT-Austin).[2] He continued developing the technology as a Masters and PhD student with the help of Dr. Joe Beaman, a professor at UT-Austin.[3] After several years of trial-and-error, Deckard's machine was capable of manufacturing real parts. He licensed the technology from UT-Austin and co-founded Desk Top Manufacturing (DTM) Corp. in 1987.[3] DTM Corp. specialized in rapid prototyping and manufacturing systems for manufacturers and service bureaus. DTM Corp. was acquired by 3D Systems in 2001 at a $45 million valuation.[4] Deckard became an engineering professor at Clemson University after DTM's acquisition.[3] After three and a half years, Deckard returned to Austin to work on the Deckard Engine, a four-stroke engine aimed at replacing emission-emitting two-stroke engines in small, hand-held products.[2]

The majority of Deckard's work is in the additive manufacturing industry.[3] In 2012, Deckard co-founded Structured Polymers LLC, a company that develops novel polymers for SLS machines.[5]
