Productivity in a new dimension

While the “sister system” EOS M 400 runs with a single 1000W laser, the EOS M 400-4 multiplies the capacity of the EOS M 290, both ensuring  proven DMLS quality. All EOS M 290 processes can be transferred to the EOS m 400-4 while retaining equivalent part properties

EOS M 400-4: Four lasers for more productivity

Building volume plus speed

  • Large building volume of 400 x 400 x 400 mm with four 400 watt lasers operating independently
  • The four precise 400 watt fibre lasers operate in a 250 mm x 250 mm square each with an overlap area of 50 mm
  • High build rate of 100 cm³/h

4 Lasers – First-class DMLS quality

  • Exceptional beam and power stability provides highest DMLS part quality
  • All processes running on the EOS M 290 can be transferred to the EOS M 400-4 and deliver equivalent part properties.
  • New and patented EOS ClearFlow Technology ensures consistent process gas management for ideal build conditions
  • Extensive monitoring features ensure high process stability and part quality

High productivity platform with smart process flow

  • Wide range of materials: from light metals to stainless and tool steels to superalloys
  • Easy handling through a high degree of automation in workflow and operation
  • Intuitive user interface, flexible software tools and a variety of additional equipment fulfill industrial production requirements
