Lasertec 30 SLM 3D printer features strengthened design

The new, third-generation Lasertec 30 SLM 3D printer now uses a rigid cast structure based on the material and design of DMG Mori’s milling and turning machines.

DMG Mori chose to use casting to resist thermal expansion during unavoidable temperature changes.

The process chamber is in an isolated unit within the printer and is free to expand and contract in all directions as the temperature varies.

The distance between the optics and the surface layer of the powder bed is kept constant through the calibrating of the bi-directional recoater, compensating for any displacement in the Z-axis.

The selective laser melting platform has been redesigned in the new model to ensure repeatability and thermal stability.

A fully overlapping quad laser working area and a build volume of 325 x 325 x 400 mm is intended to “appeal to a large section of the market,” says DMG Mori.

Their newest Lasertec has no appreciable forces transmitted to the structure from movement of the axes.

The rePlug unit, an automated powder processing unit that can be exchanged with other units, reduces time between builds by simplifying the processing of different materials.

It ensures top quality powder is in use by sieving, storing and preparing excess powder for reuse in a closed loop. This minimises oxidation and moisture build-up.

It is also possible to exchange the build container while preserving the inert gas atmosphere inside the machine.

Disruption during the print cycle is minimised by monitoring the surface of the powder bed with a camera.
