Partial project: Selective Laser Melting of implant-specific specimen made of a near-beta Ti-Nb-Zr alloy and characterization of their microstructural and biofunctional properties
For the fabrication of implants, laser-based technologies are gaining rapidly growing importance. Additive Manufacturing techniques such as Selective Laser Melting (SLM) are regarded as THE key technologies for metal implants. They offer a great potential for the fabrication of patient-specific bone implants. In the focus of current research on bone implant materials, are novel (near-) beta Ti alloys, with biocompatible compositions. Owing to their low Young’s modulus values, they can lead to effectively reduced implant stiffness and thus, to improved adaption to bone properties. Likewise, implant surfaces with best suitable biofunctional properties are important. For novel Ti alloys, new concepts are being developed for attaining tailored implant surface functionality with regard to roughness, topography and chemistry enabling improved osseointegration. Those new developments are in particular relevant for patients with systemic bone diseases like osteoporosis.
Aim of the OsteoLas project is the material-specific development of an integrated laser technology-based process chain for the fabrication of orthopedic specimen made of a novel near-beta Ti-Nb-Zr alloy with tailored microstructure and surface properties. At IFW Dresden, metallic implant-relevant specimen is fabricated by means of Selective Laser Melting (SLM). The effect of process parameters on the morphology and the microstructure and on resulting mechanical properties are investigated in detail. The optimum parameters for the fabrication of specimen with low stiffness, high strength and with maximum design flexibility will be identified. In cooperation with the group Surface functionalization at the Fraunhofer Institute for Material and Beam Technology (IWS) (Link), tailored surface structures with different roughness, topography and chemistry are realized by means of the innovative Direct Laser Interference Patterning (DLIP) and those states are characterized by surface analytical methods. The biocompatibility of these new materials will be evaluated by means on cell biological studies. Based on the gained knowledge, optimum parameter sets will be employed or the fabrication of demonstrators, i.e. complex implant geometries and their performance will be assessed.
