Purpose: The aim of the article is to present and compare the results of studies into mechanical properties, including mainly tensile and compressive strength of scaffolds fabricated from Ti and Ti6Al4V in Selective Laser Sintering (SLS) for specific sintering conditions. Design/methodology/approach: Titanium scaffolds characterised by the different size of pores were fabricated on the basis of 3D CAD models of samples for tensile and compressive strength examinations prepared with AutoFab software for a selected unit cell. The so prepared samples were subject to tensile and compressive strength examinations with a universal tensile testing machine Zwick 020. Findings: The results of examinations of mechanical properties of pristine titanium and its alloy Ti6Al4 showing differences in the strength of the two materials and allowing to characterise each of them. The size of pores and the shape and manner of arrangement of a unit cell building the scaffold influences substantially the strength properties of titanium scaffolds. Practical implications: The scaffolds with specific strength properties fabricated in the SLS process create conditions for their application in dental engineering and in jaw-face reconstructions. Originality/value: The original results of tensile and compressive strength examinations of the created scaffolds. The innovative application of the rapid manufacturing technology for the purpose of regenerative medicine may greatly influence the development of this field of medicine.
