The porous scaffolds can obtain matching elastic modulus with human bone by adjusting the pore size and porosity ( Kelly et al., 2019), and at the same time have better yield and fatigue strength ( Chen et al., 2018). Nevertheless, the elastic modulus of dense metals is much greater than that of human bones, which is prone to bone resorption and leads to bone loosening in the human body ( Bundy, 2008). Common biomedical metal materials such as Ti and Ti alloys can completely meet bone implants needs in terms of strength. Mechanical properties mainly include better yield strength, matching elastic modulus, and better fatigue strength ( Yuan et al., 2019). To simulate the mechanical properties and biocompatibility of real bone, porous metal scaffolds not only have interconnected porous structures but also have good mechanical properties and biocompatibility ( Li et al., 2020a).

Therefore, it is ideal to seek natural bone replacement for bone transplantation in orthopedics.Īs an alternative material, porous metal scaffolds avoid a series of adverse reactions in natural bone grafting and have gradually attracted researchers’ attention. In contrast, allogeneic bone transplantation has an obvious risk of immune rejection and infection, which affects bone formation and is prone to bone resorption. Autologous bone transplantation is considered to be a good choice, but the mismatched performance of different bone sites and the limited number of useful bone grafts limit the application of autologous bone transplantation ( Henkel et al., 2013). Finally, we look forward to the development prospects of AM in porous metal scaffolds.īone defects caused by pathologies such as fracture, bone tumor, or external trauma are among the main problems in clinical treatment ( Moiduddin et al., 2017). Then the applications of different metal materials in bone scaffolds are summarized, and the advantages and limitations of various scaffold design methods are discussed. This article reviews the research progress of porous metal scaffolds, and introduces the AM technologies used in porous metal scaffolds.

In recent years, many new metal materials and innovative design methods are used to fabricate porous scaffolds with excellent mechanical properties and biocompatibility. With the advancement of additive manufacturing (AM) and computer-aided technologies, the development of porous metal scaffolds also ushers in unprecedented opportunities. However, traditional processing methods are challenging to fabricate scaffolds with a porous structure, limiting the development of porous scaffolds. Metal porous scaffolds have good prospects in bone tissue replacement due to their matching elastic modulus, better strength, and biocompatibility. 5Tianjin Key Laboratory of Composite and Functional Materials, School of Material Science and Engineering, Tianjin University, Tianjin, Chinaĭesign an implant similar to the human bone is one of the critical problems in bone tissue engineering.4Renji Hospital, Shanghai Jiao Tong University, Shanghai, China.3Affiliated Hospital of Youjiang Medical University for Nationalities, Baise, China.2State Key Laboratory of Metal Matrix Composites, Shanghai Jiao Tong University, Shanghai, China.1College of Mechanical and Electronic Engineering, Shandong University of Science and Technology, Qingdao, China.Yuting Lv 1,2 Binghao Wang 1 Guohao Liu 1 Yujin Tang 3* Eryi Lu 4* Kegong Xie 3 Changgong Lan 3 Jia Liu 3* Zhenbo Qin 5 Liqiang Wang 2
