Carl Robert Deckard, Ph.D, ME (1961 - December 23, 2019) was an American inventor, teacher, and businessman, best known for inventing and developing Selective Laser Sintering (SLS), a method of 3D printing. [1] He died at the age of 58, on 23 December 2019. [2]
Deckard initially came up with the idea for SLS as an undergraduate at the University of Texas at Austin (UT Austin). [3] He continued developing the technology as a Masters and PhD student with the help of Dr. Joe Beaman, a professor at UT Austin. [4] 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. [4] 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. [5] Deckard became an engineering professor at Clemson University after DTM's acquisition. [4] 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. [3]
The majority of Deckard's work was in the additive manufacturing industry. [4] In 2012, Deckard co-founded Structured Polymers LLC, a company that develops novel polymers for SLS machines. [6]
Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material, aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. It is similar to selective laser melting; the two are instantiations of the same concept but differ in technical details. SLS is a relatively new technology that so far has mainly been used for rapid prototyping and for low-volume production of component parts. Production roles are expanding as the commercialization of AM technology improves.
Stereolithography is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and oligomers to cross-link together to form polymers. Those polymers then make up the body of a three-dimensional solid. Research in the area had been conducted during the 1970s, but the term was coined by Chuck Hull in 1984 when he applied for a patent on the process, which was granted in 1986. Stereolithography can be used to create prototypes for products in development, medical models, and computer hardware, as well as in many other applications. While stereolithography is fast and can produce almost any design, it can be expensive.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with the material being added together, typically layer by layer.
3D Systems Corporation is an American company based in Rock Hill, South Carolina, that engineers, manufactures, and sells 3D printers, 3D printing materials, 3D printed parts, and application engineering services. The company creates product concept models, precision and functional prototypes, master patterns for tooling, as well as production parts for direct digital manufacturing. It uses proprietary processes to fabricate physical objects using input from computer-aided design and manufacturing software, or 3D scanning and 3D sculpting devices.
Electron-beam additive manufacturing, or electron-beam melting (EBM) is a type of additive manufacturing, or 3D printing, for metal parts. The raw material is placed under a vacuum and fused together from heating by an electron beam. This technique is distinct from selective laser sintering as the raw material fuses have completely melted. Selective Electron Beam Melting (SEBM) emerged as a powder bed-based additive manufacturing (AM) technology and was brought to market in 1997 by Arcam AB Corporation headquartered in Sweden.
Rapid prototyping is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data. Construction of the part or assembly is usually done using 3D printing or "additive layer manufacturing" technology.

Digital modeling and fabrication is a design and production process that combines 3D modeling or computing-aided design (CAD) with additive and subtractive manufacturing. Additive manufacturing is also known as 3D printing, while subtractive manufacturing may also be referred to as machining, and many other technologies can be exploited to physically produce the designed objects.
Z Corporation it a company that makes 3D printing and scanning technologies. It was founded in December 1994 by Marina Hatsopoulos, Walter Bornhorst, James Bredt and Tim Anderson, based on a technology developed at MIT under the direction of Professor Ely Sachs. The Company was sold to Contex Holding in August 2005, and was ultimately acquired by 3D Systems on January 3, 2012.
Selective laser melting (SLM) is one of many proprietary names for a metal additive manufacturing (AM) technology that uses a bed of powder with a source of heat to create metal parts. Also known as direct metal laser sintering (DMLS), the ASTM standard term is powder bed fusion (PBF). PBF is a rapid prototyping, 3D printing, or additive manufacturing technique designed to use a high power-density laser to melt and fuse metallic powders together.
Binder jet 3D printing, known variously as "Powder bed and inkjet" and "drop-on-powder" printing, is a rapid prototyping and additive manufacturing technology for making objects described by digital data such as a CAD file. Binder jetting is one of the seven categories of additive manufacturing processes according to ASTM and ISO.

The company develops and manufactures 3D printers and related software and consumables. It raised nearly $3 million in a Kickstarter campaign and created the Form 1, Form 1+, Form 2, Form Cell, Form 3, Form 3L, Fuse 1, Fuse 1+ and Form Auto stereolithography and selective laser sintering 3D printers and accessories.
Fused filament fabrication (FFF), also known as fused deposition modeling, or filament freeform fabrication, is a 3D printing process that uses a continuous filament of a thermoplastic material. Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the growing work. The print head is moved under computer control to define the printed shape. Usually the head moves in two dimensions to deposit one horizontal plane, or layer, at a time; the work or the print head is then moved vertically by a small amount to begin a new layer. The speed of the extruder head may also be controlled to stop and start deposition and form an interrupted plane without stringing or dribbling between sections. "Fused filament fabrication" was coined by the members of the RepRap project to give an acronym (FFF) that would be legally unconstrained in its use.
3D metal moulding, also referred to as metal injection moulding or (MIM), is used to manufacture components with complex geometries. The process uses a mixture of metal powders and polymer binders – also known as "feedstock" – which are then injection moulded.
Three-dimensional (3D) microfabrication refers to manufacturing techniques that involve the layering of materials to produce a three-dimensional structure at a microscopic scale. These structures are usually on the scale of micrometers and are popular in microelectronics and microelectromechanical systems.
