SLM Metal 3D Printer

Using MPBF™ (Metal Powder Bed Fusion) technology, EP-M1250 is using a larger building envelope and nine-laser system 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 alloy, maraging steel, stainless steel, cobalt chrome and other materials. It is suitable for the direct manufacturing of large size, high-precision and high-per- formance parts in the aerospace, aviation, automotive and machinery industry.
