Abstract
The production of the hydroxyapatite baser bone implants by the direct sintering using laser additive technologies is promising. However, atthe present time, the direct melting of the hydroxyapatite technologies make it possible to obtain the spatial XY resolution not better than 2 mm, while for a real products about 200 µm are required. The production process is characterized by the wide range of parameters, and carrying out field experiments for the selection ofthe processing modes, allowing to increase the resolution, requires a lot of time. In this regard, the numerical model that allows to simulate the process of selective laser melting of the hydroxyapatite powder has been developed and implemented. This model can be applied to determine the acceptable range of the processing parameters.
