Electron beam melting (EBM) and selective laser melting (SLM) are advanced manufacturing technologies that create complex metallic structures from CAD data, affecting their biocompatibility.
In a study comparing Ti6Al4V samples produced by EBM and SLM, both methods demonstrated good cytocompatibility and haemocompatibility, revealing low haemolytic ratios and no skin irritation in animal tests.
Although SLM showed slightly better results in certain aspects, no significant differences in biocompatibility were found between the two manufacturing methods.
