SLM 125

The SLM ^® 125 is a flexible manufacturing system with a powerful laser. The machine is used in particular for the production of prototypes and qualified components in small series. It processes all SLM ^® metal powders, including reactive materials. Processes developed on the SLM ^® 125 can later be transferred to larger SLM ^® systems. This is particularly interesting for beginners in metal-based additive manufacturing. Research institutes also benefit from the material development module.  The SLM®125 is an entry-level machine that offers a printing volume of 125 x 125 x 125 mm, hence its name, and provides more accessibility than other metal solutions. It uses the powder bed laser fusion process, which relies on a standard 400W fiber laser. According to the German manufacturer, the SLM®125 offers 160% more volume than competing solutions, using 80% less powder. This is because the machine uses an optimized gas filtration system that improves the gas flow.

The SLM®125 is compatible with nickel alloys, aluminum, stainless steel, titanium, and chrome-coal, and can process reactive and non-reactive metals. The machine is equipped with a powder screening system to ensure high-quality printing, which separates oversized particles from those ready to be fused.

The SLM®125 is suitable for tooling parts with integrated cooling channels, such as tooling inserts, and is also popular in the medical sector for the production of custom-made implants, among other things. It is an ideal solution for anyone interested in starting industrial metal 3D printing
