...Shu Wang; Xueqin Zheng; Cunfu Wang; Huageng Luo; Shikai Jing This paper presents formulations for hybrid casting and additive manufacturing (AM) in the density-based topology optimization. A location-based Heaviside function is introduced to represent the parting surface. The optimized part on two...

... developed that allows for trimming of unnecessary lattices while simultaneously ensuring that the geometry remains self-supporting during the AM build process. This filter is incorporated seamlessly within the topology optimization routine. This increases the optimality of the resulting design when compared...

...Benjamin M. Weiss; Joshua M. Hamel; Mark A. Ganter; Duane W. Storti The topology optimization (TO) of structures to be produced using additive manufacturing (AM) is explored using a data-driven constraint function that predicts the minimum producible size of small features in different shapes...

...Jikai Liu; Huangchao Yu Most of the existing self-support topology optimization methods restrict the overhang inclination angle to be larger than the self-support threshold value. However, for some additive manufacturing processes, such as fused deposition modeling, horizontal overhangs with zero...

... of a user which causes increased contact stiffness “erroneously” to avoid penetration of contacting node pairs in an FE solution; and (ii) the reliability of solutions varies according to the chosen computational contact method. This paper is devoted to the topology optimization of machine tools...
