Topology optimization methods in the program complex 3D Printer

Within the scope of the project “Developing the atlas of typical forms of topological optimization of constructions with selected laser melting and its industrial verification” (contract with Ministry of Education and Science № 2016-14-579-0009-492) software, that allows topological optimization of parts with different limitations of objective function and generation and usage of different types of mesh structures to fill part’s volume, is made by participants NUST “MISiS”, NPO “TSNIITMASH”, RFNC “VNIIEF”, Russian Ministry of Education and Science, “Science and Innovation” JSC (SC Rosatom). The article contains description of methods and algorithms of topological optimization of constructions with strain and stress limitations of objective function, that were developed for the benefit of using them in basic version of software.
