Abstract Scope |
Recent advances in laser powder bed fusion (L-PBF) additive manufacturing of metals involve the use of lasers with tuneable intensity profiles enabling the control of the energy distribution and hence of the thermal gradients and the solidification pathway during the material deposition process. In this work, we present current developments involving the use of various laser sources applied in a L-PBF platform from Aconity3D GmbH. Several case studies will be presented to showcase tailoring microstructural features and mechanical performances of components built using both traditional laser sources with a Gaussian intensity distribution and those in which the emission profile is controlled (i.e. ring beam or top hat) at discretion while shifting the productivity to the next level. Results are presented for several materials of interest in the fields of aerospace, automotive and medical, and to the larger additive manufacturing community. |
