Selective laser melting (SLM), as one of the developed innovative additive Manufacturing (AM) technologies, is a powder bed-based manufacturing method, where parts are produced layer by layer through selectively fusing powder bed areas from a 3D computer-aided-design (CAD) model. In addition, the cooling rate in the SLM process can be up to 10³-10⁸ K/s, which is observably higher than the critical cooling rate for the formation of amorphous phases in most metallic glasses. Accordingly, SLM offers a new class of manufacturing processes for metallic glasses to produce parts with highly complex and functional structures for medical applications. The properties of the SLM-manufactured parts can be strongly influenced by processing parameters such as laser power, scanning speed, hatch space, and layer thickness. Therefore, it is important to understand the impact of these parameters and optimize them during the manufacturing process to produce parts with the appropriate properties.

In the present work, Ti-Zr10-Nb15-Si15 powder material composed entirely of biocompatible elements was produced and characterized by its various properties, including particle size distribution, microstructure, and biocompatibility. Based on this powder, the effect of SLM processing parameters on the quality of the manufactured parts, such as relative porosity and microstructure, was investigated, and the amorphous phase formed during the SLM process of Ti-Zr10-Nb15-Si15 was analysed. In addition, the hardness of SLM-manufactured Ti-Zr10-Nb15-Si15 Parts is over 700 HV, which can be compared to the values of other titanium-based metallic glasses.
