Abstract The integration of topology optimization (TO) and additive manufacturing (AM) technologies can create significant synergy benefits, while the lack of AM-friendly TO algorithms is a serious bottleneck for the application
of TO in AM. In this paper, a TO method is proposed to design self-supporting structures with an explicit
continuous self-supporting constraint, which can be adaptively activated and tightened during the optimization
procedure. The TO procedure is suitable for various critical overhang angles (COA), which is integrated with
build direction assignment to reduce performance loss. Besides, a triangular directional self-supporting constraint
sensitivity filter is devised to promote the downward evolution… More >
