SLM Metal 3D Printer

EP-M1550 is using a large building envelope and 16-laser system to ensure high-efficiency production. The multi-laser precise positioning and innovative area splicing control technology offer uniformity and stability throughout the whole printing phase.


Compatible with titanium alloy, aluminum alloy, nickel alloy, maraging steel, stainless steel and cobalt chrome, etc. EP-M1550 is an ideal choice for direct manufacturing of large-size, high-precision, and high-performance parts for aerospace & aviation and other industries.

EP-M1550 Metal 3D Printer Features

    • Printing of oversize parts in the 2670 Liter build chamber.

    • 16 lasers are printing simultaneously with speed up to 650 cm³/h.

    • Excellent beam and power stability, as well as energy control strategies can inhibit porosity, micro-cracks and non-fusion defects.

    • Excellent high beam quality (M²≤1.1) and detail resolution ensure the forming accuracy and mechanical properties of printed parts.

    • Print density > 99.9% and fluctuation of mechanical properties < 5%.

    • Optimized design of wind field structure ensures effective removal of dust and splash and uniform printing of full-format parts.

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

    • With automatic cleaning (backblowing), the filtration system can realize online back blowing during printing.

    • Equipped with permanent filter elements.

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

    • Real-time monitoring of working environment and air source status, safe and reliable.

    • The equipment has passed the EU CE certification and FDA laser safety certification, with high safety.

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

    • Automatic powder circulation under inert gas protection environment can be realized, with complete closed operation to realize powder isolation, simple and safe operation.
