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.

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.

Is 400 mm xyz 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.

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. Watch the video

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. Watch the video

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. Watch the video

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.
