HQ-PM-AM - Powder and Materials Design for Flexible High-quality Additive Manufacturing

Start date 01/10/2015
End date The project is closed: 30/09/2018
Additive manufacturing comprises a number of rapidly growing manufacturing technologies, amongst which selective laser melting (SLM) is the main powder-bed based method for metallic parts. From materials point view, the parts quality very much depends on the proper consideration of powder characteristics and metallurgical principles for materials being processed. For difficult-to-build materials like certain Ni-base alloys, we intend to focus on the metallurgical aspects to understand how defect generation can be minimized, while for easy-to-build materials we will explore the limits in product design with respect to e.g. wall thickness/lightweight design. As a generic support, we will also address powder characteristics like powder rheology and powder surface chemistry to depict their role with respect to powder-bed quality and powder in-process recyclability. As a final touch, we will integrate novel approaches for rapid laboratory design of powder towards pilot/industrial atomized powder fabrication, whereby a novel approach for rapid development of materials for AM could be anticipated.
