3D Systems Introduce the InVison^TM system commercially in October, 2003 which is similar to the Objet PolyJet^TM process described above.

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 scheduled to be introduced in the summer of 2007, at a price of US$9,900.

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.

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 JSR and D-MEC (both of Japan).

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.
