SLM Metal 3D Printer

Using MPBF (Metal Powder Bed Fusion) technology, the EP-M650 is using a 650 x 650 x 800 mm build envelope and four laser systems to ensure a high efficiency printing production. The precise positioning and innovative area splicing control technology hereby 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, Die Steel, Stainless Steel, Chrome Cobalt Alloys and other materials. This large format metal 3d printer is suitable for the direct manufacturing of large-size, high-precision and high-performance parts in the aerospace, aviation, automotive and energy, oil & gas industry.

EP-M650 Metal 3D Printer Features

  • EP-M650 Metal 3d Printer Feature High Effciency Productivity
    High Effciency & Productivity
    • Printing of mass-individualized parts in the 340 Liter  (650 x 650 x 800 mm) build chamber.

    • Four lasers are printing simultaneously with up to 190 cm³, which increased efficiency by 3.5 times compared to a single laser system.

    • Printing large layer thicknesses of more than 60 um is possible.

  • EP-M650 Metal 3d Printer Feature Stable Quality Good Consistency
    Stable Quality, Good Consistency
    • High parts accuracy in the overlap area of 0.1 mm. The deviation of mechanical properties compared to a single laser system is lower than 3%.

    • Optimized design the air flow ensures the effective removal of dust and splatter as well as a unifrom parts quality in the whole print bed.

    • The strict calibration ensures the consistency between parts and batches.

  • EP-M650 Metal 3d Printer Feature Humanized Design High Automation Degree
    Humanized Design, High Automation Degree
    • Friendly user interface with fully automatic one-click printing function.

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

    • The one-piece take out function ensures a high automation and low downtime, due to an automatic movement of the building cylinder into the cleaning module after the print is finished.

  • EP-M650 Metal 3d Printer Feature Real Time Monitoring High Security
    Real Time Monitoring, High Security
    • Safety design, prevent misoperation, 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.

  • EP-M650 Metal 3d Printer Feature Perfect After Sales Service
    Perfect After-sales Service
