Code for Designing Variable Density Supports in SLM Process by Topological Optimization Method

This paper presents a method for designing support structures for 3D printing based on the topological optimization and the method of equivalent static loads. Information exchange between the optimization and numerical simulation modules of the SLM process is organized for the computational process. The proposed support synthesis method effectively reduces the maximum shrinkage deflection from 0.731 to 0.630 mm, which corresponds to a reduction of 13.8 % .
