    Laser powder bed fusion (L-PBF) can accurately and efficiently produce complicated structures made of various medical metals, giving orthopedic implants with customized macro and micro geometry, so that they can quickly respond to personalized clinical treatment needs according to the specific physiological environment, and accelerate the process of bone repair and reconstruction to the greatest extent. This article firstly introduces the current development of metal orthopedic implants fabricated by the L-PBF from the perspective of biomaterials, structural design and manufacturing process in general. Then, it discusses the unique processing characteristics and mechanical properties of non-degradable metals such as titanium and tantalum alloys and biodegradable metals such as magnesium and zinc alloys. Finally, the future development of the L-PBF in the field of orthopedic implants preparation is prospected.
