1-Meter-Tall 3D-Printed Copper Combustion Chamber
M 4K

For big sized applications

More Space.

AMCM M 4K – THE MACHINE – for big sized applications.

The AMCM M4K, based on the EOS M 400, increases the building height to 1 m (just over 3 feet), with a machine height of "only" 3 m (just under 10 feet). All this available now with the AFX nLIGHT laser.

  • 1 m

  • 4x

Is 400 mm³ not enough?

In case you need more space and power e.g., 1.5 m in z-height and 6 x 1.2 kW. AFX nLIGHT lasers, we are ready to customize. Still too small? Check out our AMCM M 8K.

AMCM M4k from the side

Light Engine

From 4 x 1 kW up to 6 x 1.2 kW nLIGHT AFX lasers.

Thermal Management

Power is nothing without control. Additional thermal load is taken care of with 3x the chilling capacity compared to an EOS M 400.

Improved Inert Gas Flow

To guarantee the same process conditions throughout a 1 m tall build we optimized the inert gas flow of the process chamber.

Build Volume

Large building volume of 450 x 450 x 1,000 mm.

Powder Management

For our closed and open loop solution we rely on our partner Volkmann. If these solutions do not fit your need, we are open for a tailormade solution.

Small Footprint

6,340 x 3,450 x 3,900 mm (W x D x H).

Beam Shaping

If equipped with 1.2 kW AFX nLIGHT: From Gaussian to ring-shaped beams, from 85 – 210 µm spot size.
