Irepa Laser (France) A laser research center that is developing the CLAD® process (French acronym for Construction Laser Additive Directe). It uses a single fiber laser and a coaxial powder-delivery nozzle to make small, fully-dense parts out of a number of materials. The group has also combined this process with more conventional ones to provide a wide range of capabilities. See Simon Sankaré's blog for many photos and a detailed description.

Optomec, Inc. Commercialization of the Laser Engineered Net Shaping process (TM) (LENS ®) developed at Sandia. LENS ® and Laser Enginered Net Shaping (TM) are registered trademarks of Sandia National Labs. and Sandia Corp. The company's tradename for the technology is the Direct Metal Deposition System^TM (DMDS^TM).

POM Group Provides Direct Metal Deposition^TM technology, a laser powder forming process and also operates as a service bureau. Focused on the injection molding tool market.

Sciaky, Inc. The company supplies EBFFF (Electron Beam Free Form Fabrication) technology, based on work originally carried out by NASA. An electron beam melts a wire feedstock and deposits material in layers at up to 40 lbs per hour. EBFFF can use a wide variety of materials, as well as multiple materials, and is energy-efficient compared to laser-based systems.

Controlled Metal Build-up (CMB) (Germany) This is a process for direct manufacture of metal objects developed at the Fraunhofer Institute. It's a laser powder forming process, but each layer is milled flat before addition of a subsequent layer. The procees was being commercialized by Albrecht-Roeders, Germany, but technical problems have forced indefinite delays.
