Production and processing of
metal powder
Production of individual metal powders in small quantities
Certified production
We produce metal powder of the highest quality from known or individually alloyed materials in a TÜV-certified process chain for metal 3D printing. In addition to atomization, we also offer preparation for the required particle size distribution, including comprehensive analysis and certification.
Metal powder atomization
The Atomiser AU 3000 from BluePower Casting Systems was developed for the fast and economical production of small quantities of high-quality metal powder up to around 50 kg. Compared to large production systems, frequent alloy changes are also possible without cross-contamination. With a crucible-based system, argon hot gas flow and the close-coupled atomizer, liquid metal is turned into spherical metal powder for additive manufacturing processes in the atomization chamber.
Metal powder processing
With our preparation systems, we can optimize the metal powder for your metal 3D printing process by sieving, sifting and drying. The quality of the metal powder used is crucial for high reproducibility in the additive manufacturing process. Characteristic features include particle size distribution, particle shape and residual moisture. These have a decisive influence on the bulk density and flowability of the metal powder. The energy input of the laser, which is dependent on the metal powder, has a direct effect on the material structure and the functional properties of the component. Comprehensive quality assurance with subsequent processing is necessary to control the parameters mentioned and to additively manufacture high-quality components with good mechanical and technological properties.
Metal powder analysis
The metal powders can be fully analyzed in our modern and extensively equipped laboratory.
- Full chemical analysis DIN 51418-1:2008-08 and DIN 51418-2:2015-03
- ONH analysis (oxygen, nitrogen and hydrogen analysis) according to EN ISO 15351:2010-08
- CS analysis (carbon and sulphur analysis) according to DIN EN ISO 15350:2010-08
- Particle size distribution and particle shape of metal powder with the Retsch Camsizer X2 according to ISO 13322-2
- Flowability and bulk density using a Hall flowmeter in accordance with DIN EN ISO 4490-1 and DIN EN ISO 3923-1
- Coating suitability with own recoater test
