MHI Machine Tool adds two new features to LAMDA metal 3D printer

June 28, 2019

Two innovative functions enhance accuracy and part quality

Mitsubishi Heavy Industries Machine Tool (MHI Machine Tool) held a technical briefing session on May 16, 2019, at its Tokyo headquarters, where it announced two new functions for its additive manufacturing (AM) machine “LAMDA.” President Keiichiro Iwasaki emphasized, “These two functions will be the biggest differentiators.” Both are regarded as the world’s first practical applications in their respective areas.

Real-time monitoring and local shielding

The first function is a real-time “monitoring” feature that tracks the melting state of the material during the AM process. This system provides feedback data to help stabilize the shaping accuracy.

The second function is a “local shield,” which uses a shielding gas to purge oxygen from the processing area. This prevents air from entering the melting zone, enabling the formation of non-oxidized parts.

Presented at RAPID+TCT2019 in the U.S.

LAMDA was exhibited at RAPID+TCT2019, a major additive manufacturing event held in Detroit, United States, from May 20 to 23, 2019. LAMDA is a directed energy deposition (DED) system that MHI Machine Tool launched in March 2019.

The development of LAMDA and its advanced functions is based on the research results of the Next Generation 3D Laminated Molding Technology Development Organization (TRAFAM), a technology research cooperative involved in the project.
