Whitepaper: Multi-Machine Capability Study Repeatability is Key for Distributed Serial Production

This whitepaper investigates the performance of a standardized test job layout built on three different EOS M 290 systems using EOS Titanium Ti64ELI. In a nutshell, the results verify that the EOS M 290

  • Shows a high capability of more than 4 Sigma for the tensile properties across the three machines located in different facilities
  • Proves that the DMLS process remains repeatedly capable and above the ASTM requirements for Ti64 ELI
  • Verifies that EOS systems are ready for decentralized serial additive manufacturing

Whitepaper: EOS/Linde influence of oxygen in the print process chamber Effect on the critical properties of aluminium alloy AlSi10Mg

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
