SLM Metal 3D Printer

Using MPBF (Metal Powder Bed Fusion) technology, the EP-M1250 is using a 1250 x 1250 x 1350 mm build envelope and nine laser systems to ensure a high efficiency production. The precise positioning and innovative area splicing control technology offers uniformity and stability throughout the whole printing phase.

The system can operate with various metal powders such as Titanium, Aluminum and Nickel-based alloys, Maraging Steel, Stainless Steel, Chrome Cobalt Alloys and other materials. It is suitable for the direct manufacturing of large size, high-precision and high-performance parts in the aerospace, aviation, automotive, machinery and oil & gas industry.
