Composite scaffolds can be produced from polymers as a matrix with osteoconductive ceramics as a filler for bone regeneration, to improve the bioactivity. By Selective Laser Sintering (SLS) micro- and macro-architecture products may be manufactured from a CAD model. In this work, SLS was used to print scaffolds from ultra-high-molecular-weight polyethylene (UHMWPE) as a matrix with 5 or 10 wt% added calcium phosphate for bone tissue regeneration. The range of porosity values obtained for the scaffolds was 60 to 90%, and the pore size range observed by SEM was 20 to 100 µm. The ultimate strength was highly dependent on porosity, which was respectively proportional to increasing amounts of calcium phosphate added to UHMWPE. The values obtained in this work are in the range of strength for the cortical bone, though.
