Abstract

This article presents studies of the of lightweight mesh structures properties made by selective laser melting technology. The study of lattice structures with different sizes of struts was made. Also, methods for optimizing grid structures with variable strut sizes were also used. The structure of the mesh elements after hot isostatic pressing and heat treatment was studied. The results of changes in porosity and mechanical properties of lattice structures after hot isostatic pressing and heat treatment as compared with properties of cortical bone are shown. The presented results can be used in the manufacture of medical implants in order to reduce their weight, improve implantation, while ensuring optimal mechanical properties.

Keywords: Functionally graded materials, lattice structure, titanium alloy, selective laser melting
