Purpose: The aim of the paper is to characterise titanium alloy Ti6Al4V coated by polymeric surface layer as a material for biomedical applications. The paper presents a Selective Laser Melting (SLM) method of fabrication of elements to be used as implants from Ti6Al4V powder. It was demonstrated that the metallic scaffolds created have strictly defined geometric dimensions of an object and open pores, and the pores are regular and repeat within the whole volume of the biomimetic element. Design/methodology/approach: The actual manufacturing process is preceded with creating a model of an element in the stl format that allows to present the element surface by means of a net of triangles. Once the shape is defined of a unit cell and its net parameters, i.e. height, depth and width, they are duplicated with appropriate mathematical algorithms as a result of which a strictly defined, densed and complicated structure of pores defined by a designer is created. Findings: Scanning electron microscopy was applied for showing the structure of pure scaffolds as well as composites made of Ti6Al4V scaffolds coated by polymeric surface layer. Microscope observations were performed using a SEM Zeiss Supra 35 equipped with EDS detectors for chemical composition analysis. Practical implications: Manufactured metal-polymer composites can be used in regenerative medicine as biomimetic implants. Originality/value: The characteristics of biomimetic composites, used in medicine as implants of a palate piece loss with strictly designed geometric shape and dimensions of the object and its strictly planed pores.
