EOS and Linde combined forces to conduct an important study into the influence of oxygen in the print process chamber and its effect on the critical properties of aluminium alloy AlSi10Mg. This whitepaper describes the study and its findings: The EOS M 290 with the EOS Aluminium AlSi10Mg powder and process parameters enable a high-quality, reproducible final part. An oxygen content below 1000 ppm needs to be maintained during processing to prevent increasing the number and size of pores and ensure high part density and required mechanical properties. Powder aging is reduced by keeping the O2 level below 1000 ppm which enables more frequent reuse of the powder. The position of the oxygen sensor influences the measurement, with a sensor placed near to the powder bed giving optimal measurement.

Metal 3D Printer Up to 4x more productivity. Four precise 400-watt fiber lasers. Build volume of 400 x 400 x 400 mm.

The EOS M 300-4 enables flexible adaptation to all individual requirements through various degrees of automation, helping to ensure an optimized workflow. The exceptional laser and performance stability ensures consistent part quality over the entire build space, including full coverage of overlaps. Up to four precision fiber lasers work over a 300 x 300 mm area, with each laser covering the entire space.
