Raw material and process qualification

The use of powder as a raw material constitutes an important strategy in metal AM as the properties of the powder will strongly affect the properties of the final AM component as well as robustness of the AM process The aim of this task is to establish qualification characteristics of powders for materials of interest for the user cases in dependence on process selected requirements to the component as well as cost factor Hence powder selected based on the materials and process selections in WP2 will be ordered from the materials suppliers in the project and qualified depending on the process and component requirements Powder bulk and surface chemistry as well as physical properties of the powders powder size powder particles distribution flow rheological properties etc will be evaluated and documented for each process and component Process parameters will be optimised for the powders utilized in WP4 This task will also assure consistent powder properties during the whole chain including pilot line validation and use case component manufacturing WP6 and WP7 Database of T45 will be completed accordingly
