Nidec Machine Tool LAMDA500 Mid-Size Metal 3D Printer
Nidec Machine Tool Corporation launched the LAMDA500, a mid-size model of Nidec’s DED-type1 powder metal 3D printer series. To accommodate the various shapes of industrial metal components, the maximum additive manufacturing dimensions of the LAMDA500 are 500mm x 500mm x 500mm, with standard five-axis functionality. The LAMDA 500 joins the smaller LAMDA200 and the very large LAMDA2000 in the range.
The LAMDA500 performs stable and high-quality additive manufacturing using the specially developed local protection nozzle and monitoring feedback system – two unique technologies of Nidec’s LAMDA series. Nidec Machine Tool is set to aggressively promote this latest product in European and American markets by exhibiting the LAMDA500 for the first time at JIMTOF 2022, Japan’s international machine tool exhibition, held from 8 to November 13 of this year.
Designed for the production of metal components used in aerospace, space, automotive products and construction equipment, among others. A two-axis table is fitted as standard to enable fully five-axis additive manufacturing. By using a rigid, high-precision five-axis machining center from Nidec OKK Corporation (formerly OKK Corporation) and integrating the functions required for a metal 3D printer, Nidec has developed a flexible and high-performance system. Additionally, a fully integrated closed-loop monitoring system controls laser power for consistent build quality and thermal performance, while providing build quality documentation.
Nidec developed and implemented two unique technologies for the LAMDA series. The local protection nozzle uses an inert gas shield to enable high-quality metal fabrication without an environmental chamber, while the monitoring feedback system monitors and optimizes fabrication conditions to enable high-precision, long-term fabrication and stable. The latest iteration of the coaxial nozzle developed by Nidec, the local shield area has been enlarged to 45 times its previous size to improve manufacturing speed and metal quality. In addition, LAMDA machines are equipped with a function based on AI (artificial intelligence) technology to monitor additive manufacturing conditions. The system is able to quickly detect anomalies during an additive manufacturing process, detecting and preventing errors before they occur.
Using technology to continuously spray metal powder from a nozzle, the laser melts and solidifies the powder with base materials to fabricate a desired shape. DED metal 3D printers are used for multi-layer materials and components made of several different materials. With the optional second hopper supplying powdered metal, LAMDA systems can change material during a build process producing functional gradient materials, which are printed by changing the material mix during the build process.
