Abstract: Laser powder bed fusion (LPBF) makes it possible for biodegradable zinc (Zn) to be used to produce customized orthopedic implants. In this research, we investigate the impact of laser power and scanning speed on the development of surface quality, relative densification, and texture during LPBF of zn implants. Increasing laser power was able to decrease melt viscosity and surface tension, which improved the metallurgical bonding between adjacent tracks. Uneven and twisted tracks also became continuous and straight. Scanning speed could control molten-pool temperature to restrain grain natural orientation, achieving various crystal orientations and a weakened texture. Importantly, it further avoided the thermal expansion and contraction caused by excessive energy storage and accumulation in the matrix, thus reducing the generation of high-dislocation density. As a result, by selecting a reasonable laser power and scanning speed, the LPBF parts exhibited a flat surface morphology and a high density over 99.5%. Their average hardness, mechanical strength, and elongation reached 50.2 HV, 127.8 MPa, and 7.6%, respectively. Additionally, the parts displayed a moderate degradation rate and excellent osteogenic properties. All these results provide a basis for selecting process parameters to optimize the comprehensive properties of LPBF-processed Zn parts for biodegradable applications.
