主　　题：additive manufacturing SLM EBM porous metal implant biocompatibility 

摘      要：Biomedical metal materials with good corrosion resistance and mechanical properties are widely used in orthopedic surgery and dental implant materials,but they can easily cause stress shielding due to the significant difference in elastic modulus between the implant and human *** elastic modulus of porous metals is lower than that of dense ***,it is possible to adjust the pore parameters to make the elastic modulus of porous metals match or be comparable with that of the bone *** the same time,the open porous metals with pores connected to each other could provide the structural condition for bone ingrowth,which is helpful in strengthening the biological combination of bone tissue with the ***,the preparation technologies of porous metal implants and related research have been drawing more and more attention due to the excellent features of porous *** laser melting(SLM)and electron beam melting technology(EBM)are important research fields of additive *** have the advantages of directly forming arbitrarily complex shaped metal parts which are suitable for the preparation of porous metal implants with complex shape and fine *** new manufacturing technologies,the applications of SLM and EBM for porous metal implants have just *** paper aims to understand the technology status of SLM and EBM,the research progress of porous metal implants preparation by using SLM and EBM,and the biological compatibility of the materials,individual design and manufacturing *** existing problems and future research directions for porous metal implants prepared by SLM and EBM methods are discussed in the last paragraph.
