Zusammenfassung:	The invention discloses a structural topological optimization method considering additive manufacturing inclination angle constraints, and aims to solve the self-supporting problem in the structural additive manufacturing process. The method comprises the following steps: firstly, establishing a unit density updating iteration rule meeting additive manufacturing inclination angle constraints; then, adding the rule into a topological optimization model after being subjected to smooth approximate processing, taking the minimum flexibility of the structure as an optimization target to construct atopological optimization mathematical model considering additive manufacturing dip angle constraints, solving the optimization model through an OC algorithm, and obtaining the optimal configuration.The embodiment provided by the invention shows that the continuum structure topological optimization method considering the additive manufacturing inclination angle constraint is effective, the inclination angle of the topolog
