Prototype of innovating bone tissue preserving THRA endoprosthesis with multi-spiked connecting scaffold manufactured in selective laser melting technology

The paper presents the prototype of innovating bone tissue preserving THRA endoprosthesis with multi-spiked connecting scaffold - the main result of our research project: "Experimental investigation and design of the constructional properties of bone-porous implants fixations" (4T07C05629, Polish Ministry of Science, finished in February 2008) presented also as plenary lecture at the 18th International Conference "Biomaterials in Medicine and Veterinary Medicine" in Rytro (Poland), 2008. Three-dimensional selective laser melting (SLM), a direct metal manufacturing (DMM) technology from rapid prototyping/rapid manufacturing (PR/RM) group, was successfully applied to manufacture these prototypes of Ti6AI7Nb powder. We share our observations and remarks on the prototypes manufacturing in SLM laser additive technology
