Renishaw’s AM 400 laser melting system features the company’s most recent PlusPac machine updates, including a larger safe-change filter, improved optical control software, revised gas flow and window protection system. The machine is capable of building complex metal components direct from 3D CAD data, with a soft recoater blade to enable lattice and other delicate geometries.

A new 400-W optical system provides a reduced beam diameter of 70 microns, in line with Renishaw’s AM 250 200-W platform. Existing 200-W material file parameters from the AM 250 system can be directly transferred to the new machine, the company says. The increased power of the laser focused at 70 microns also enables processing materials with elevated melting temperatures, with a slight increase in energy density compared to the AM 250 system.

Open access is available to material parameter editing, while change-over between materials is rapid and flexible. A external powder hopper with valve interlocks enables the addition of material while the process is running. The hopper can be removed for cleaning or exchanged with a secondary hopper, simplifying material change-over. Powder overflow containers outside the chamber feature isolation valves, allowing unused materials to be sieved and reintroduced to the process while the system is running.

The system includes a sealed and welded build chamber, inert atmosphere generation with low argon consumption, a SafeChange filter system, and a chamber glove box for safer build removal. It is equipped with Renishaw’s QuantAM file preparation software.
