On September 2, 2026, a study by Jinan University's Guo Shusheng team, published in Metals Advances, showed that laser powder bed fusion (LPBF) of the Zn-0.8Cu zinc alloy can turn the anisotropy generated by layer-by-layer printing into a design advantage. Vertically oriented samples achieved a better strength-ductility balance due to denser CuZn₄ nanoprecipitates, which act like 'micro-shock absorbers.' Horizontally oriented samples had finer grains and reduced galvanic corrosion, leading to slower degradation. Cell experiments demonstrated good biocompatibility, making the alloy suitable for temporary implants such as vascular stents and bone screws that degrade in vivo after fulfilling their function. Value for powder buyers: (1) Medical-grade biodegradable zinc-based powders represent a niche blue-ocean segment in additive manufacturing powders, and Zn-0.8Cu validates the feasibility of the LPBF process. (2) The concept of 'tuning strength/corrosion resistance by orientation' can be replicated in developing other alloy grades. (3) The scale-up of temporary implants will drive bulk demand for medical-grade zinc alloy powders.
