Abstract
Architected UHMWPE 3D open-cell porous scaffolds simulating anisotropic trabecular bone tissue were designed and produced by a combination of 3D-printing, powder filling and hot molding, and final leaching. SEM investigations confirmed the high perfection of the struts and nodes in the open cell architecture with pore diameters in the range 0.7–3 mm. The scaffold surface texture was characterized by 250 μm asperities formed by templating of UHMWPE on the surface of PLA sacrificial 3D-printed matrix.
