The most common defects in laser powder bed fusion (LPBF) namely porosity, geometrical errors, roughness and thermal deformations are principally linked with the energy input to the process. In common practice, a single set of process parameters is u

Highly customisable implants with lattice structures can be achieved using selective laser melting (SLM) paving the way for tailored biodegradable Fe-based implants. For the first time, a systematic analysis is presented in terms of laser processing
Molten pool geometry, whose surface parameters may be extrapolated through direct process observations, has been identified as a fundamental indicator of stability in laser powder bed fusion (LPBF). However, a parameter that cannot be directly measur

The processing of Zn alloys through Laser Powder Bed Fusion (LPBF) with conventional vector-based scan strategies poses significant challenges regarding process stability. The evaporation tendency of such materials limits the quality of the process o

In energy generation applications, Ti- and Ni-alloys are widely used for their complementary features, where Ti-alloys provide lightweight structures while Ni-alloys are adaptable to high temperature use. The combination of these alloys into a single
