Abstract

Powder bed-based additive manufacturing allows the processing of demanding materials due to the high build space temperatures. In commercial machines up to 6 kW of power is available for the process, which is applied with a beam that can be moved almost without inertia. So far, such high beam powers have only been utilized to maintain the build chamber temperature, whereas the actual melting takes place at much lower power. This increases the time for melting as well as for heating and thus the overall process time. The aim of this study is to develop process strategies which enable a better utilization of the beam power and thus increase productivity. The resulting opportunities and challenges are exemplified with the Ni-base superalloy IN718.
