SLM Metal 3D Printer

EP-M825 is using a large building envelope and ten-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 building speed can be up to 410cm³/h, which is suitable for direct manufacturing of high-performance components in aerospace, mold manufacturing, automotive industry, etc.

EP-M825 Metal 3D Printer Features

    • Printing of mass-individualized parts in the 760 Liter build chamber.

    • Ten lasers are printing simultaneously with speed up to 410 cm³.

    • Bi-direction powder spreading shortens production cycle.

    • Accuracy deviation of lap area less than ± 0.1 mm.

    • High parts accuracy in the overlap area of 0.1 mm.

    • Print density > 99.9%.

    • Fluctuation of mechanical properties < 5%.

    • High quality laser beam and precise laser positioning control ensures stable & excellent print quality.

    • The optimized design of the wind flow structure effectively removes dust and splashes, ensuring that the printing surface is bright and tidy, and the sparks are bright and consistent.

    • Three-stage filtration equipped with permanent filter element brings easier maintain.

    • User-friendly interface with fully automatic one click printing function.

    • The build job information is displayed in real time with traceable printing parameters report.

    • The one-piece take out function ensures a high automation.

    • Safety design, prevent mis-operation, electric shock, fire, waste and pollution.

    • Outstanding overall sealing performance, use and recovery of powder in a closed state.

    • Environment and gas source state real-time monitoring, safe and reliable.
