Powder processing without gas wasting for additive manufacturing
assonic presents a closed loop system for reactive metal powders for the first time at Formnext 2024 Up to now, the preparation and further processing of reactive powders for modern additive manufacturing applications, such as titanium, has consumed a large amount of inert gas, which was emitted into the atmosphere after the process. In cooperation with a well-known East German university, German company assonic Dorstener Siebtechnik has now solved this problem and is going to present the first metal powder screening system with a closed gas circuit at the Formnext trade fair in Frankfurt am Main. For the first time, the SPC 500 system not only conveys the powder, but also the respective inert gas by means of a vacuum in the circuit.
This closed circuit not only reduces the sometimes enormous costs for inert gases such as argon or nitrogen to a minimum during the pre- and post-processing of reactive materials, but for the first time the sensitive preparation process can also be fully automated and carried out without manual intervention. In this way, the aluminum…
