      abstract     = {2-Component-Metal Injection Moulding (2-C-MIM) is a
                      technique derived from plastics industry which has been
                      adapted to metal powders. In the present work, the
                      production of titanium implants with a gradient in porosity
                      was demonstrated by using this technology, starting from
                      titanium feedstocks with and without space holder particles
                      (NaCl, 350-500 μm). Binder systems specially tailored for
                      the application were developed. The gradient in porosity is
                      attractive for biomedical implants, as it combines low
                      porous parts with high mechanical strength with high porous
                      parts, which promote a stable interlock between bone tissue
                      and implant. Compared to established production routes, the
                      net-shape fabrication of titanium implants by 2-C-MIM
                      promises a significant reduction of cost if aiming at large
                      scale production. The feasibility study was accompanied by a
                      detailed characterisation of each production step of 2-C-MIM
                      process including influence of MIM processing on mechanical
                      properties.},
