      abstract     = {Highly porous titanium parts in three different shapes
                      (conical, cylindrical, and semi-cylindrical) were produced
                      using metal injection molding (MIM) and the space holder
                      technique. Potassium chloride (KCl) powder was used as a
                      temporary space holder material. The frequently used
                      extraction of the KCl space holder by dissolution in warm
                      water was replaced with sublimation from the solid state
                      during vacuum sintering. This improvement enabled highly
                      porous titanium parts to be manufactured by MIM without the
                      frequently observed sample collapse or extensive shape
                      distortion. Final porosities of $55–60\%$ were achieved,
                      which is close to the recommended value for porous spinal
                      titanium implants, making improved method attractive for
                      implant manufacturing applications. An additional advantage
                      of removing the space holder by sublimation is that the
                      time-consuming salt leaching step can be omitted. A
                      systematic study of sample configuration, porosity change,
                      microstructure, and impurity uptake was conducted and the
                      sintering cycle was optimized.},
