Current research has highlighted MIM of Mg-alloys as highly suitable for biomedical implant applications. Moreover, MIM-technique possesses high potential for the SF6 free near net shape mass production of small sized and complex shaped parts like screws, nails and bone-plates. Furthermore, MIM involves a high degree of freedom regarding individual alloy- and MMC-composition using the blended elemental (BE-route). For prototyping and low quantities, the feedstock can be used for 3D-filament print, too. Hence, suture anchor screw implant demonstrator parts and test specimen could be produced very successfully. Increased mechanical properties of MIM dogbone tensile test specimen could be achieved using biomedical Mg-Ca alloy (X1, UTS: 141 MPa, YS: 67 MPa, ԑf: 7%) and Mg-Nd-Gd-Zr-Zn (ZE12, UTS: 161 MPa, YS: 120 MPa, ԑf: 3.3%). Thus, the mechanical properties are equivalent to those of as cast material and superior to those of biodegradable polymeric materials which are currently in clinical use.
