Mitsubishi Electric Corporation announced that it has developed a unique dot forming technology that realizes high-precision shaping by combining laser, computer numerical control (CNC) and computer aided manufacturing CAM technologies in 3D printers.
The technology produces high-quality three-dimensional (3D) parts with few voids at high speed, employing a laser wire directed-energy deposition (DED) method, which is an additive-manufacturing process that uses focused thermal energy to fuse materials as they are deposited. Mitsubishi Electric believes that its new technology will raise productivity in a wide range of applications, such as the “near-net” (near-final) shaping of aircraft and automobile parts and build-up repairs.
A three-dimensional metal shaping machine incorporating the new technology was exhibited for reference at the 29th Japan International Machine Tool Fair (JIMTOF2018), which was held at the Tokyo Big Sight exhibition complex. Mitsubishi Electric expects to launch a commercial version within the fiscal year ending in March 2021.
Amid increasing demands for low-volume production, 3D shaping technology is being used to manufacture metal parts, especially for aircraft and automobiles, because the technology eliminates cost-bearing needs for jigs and assemblies and improves design freedom. The global market for 3D metal shaping equipment is expected to be growing up.
