3D Systems Manufactures the InVison^TM system, which uses similar technology to the Objet PolyJet^TM process described below.

Also see the company's separate web-site for the V-Flash^TM Desktop Modeler. This is a next-generation photopolymer-based technology which is said by the company have many of the properties of stereolithography. The first machine based on the technology is priced at US$9,900.

D-MEC (Japan) D-MEC was founded as a joint venture of Sony and Japan Synthetic Rubber Corp. (JSR). The company is proceeding on its own after the exit of Sony from the RP marketplace and is now solely-owned by JSR. D-MEC also sells Acculas photopolymer-based micro-fabrication systems which it jointly developed with Laser Solutions Co. This system uses a deformable mirror device to expose layers with micron resolution. D-MEC also acts as a service bureau.

Envisiontec GmbH (Germany) The company produces the Perfactory® system which uses photopolymers and deformable mirror devices (DMD's) for layerwise imaging. They also produce the Bioplotter^TM, a system to build 3D scaffolds for tissue engineering applications. This machine is based on hypodermic dispensing of a curing material into a liquid medium.

Huntsman Advanced Materials (Switzerland) In late 2008 the company introduced a machine called Araldite® Digitalis, utilizing a MEMS-based wide-area exposure technology. While details are still preliminary, the method seems to most closely resemble Envisiontec's Perfactory® described immediately above.

Laser Solutions Co., Ltd. (Japan) The company produces photopolymer-based systems using deformable mirror device (DMD) exposure for making micro-devices. The machine was developed in conjunction with D-MEC which is responsible for marketing. See D-MEC, above.

Light Sculpting Inc. The company has been developing their very high resolution DesCAF (Design Controlled Automatic Fabrication) technology since the 1980's. The first beta system was installed in 1998. The technology has been based on the use of photomasking techniques, but the company reports they are working on systems based on deformable mirror devices and/or LCD's as exposing means. The process is said to be able to handle both multiple materials and filled materials.

microTEC (Germany) Offers manufacturing services using stereolithography-like technologies for producing very small objects and systems. Capable of batch fabrication rates to hundreds of thousands of parts per hour.

Objet Geometries Ltd. (Israel) Offers the PolyJet^TM process based on depositing photopolymer with a wide area inkjet head. Curing is layer by layer using UV exposure. Undercuts and overhangs are supported by a second, wash-away photopolymer. The company is also the first to introduce machines that can deposit two materials simultaneously.
