Support Structures for Additive Manufacturing: A Review (2018, result): “Lattice support [61] Metal AM processes”
Current and future trends in topology optimization for additive manufacturing (2018, background): “…(Huang et al. 2009), tree-like structure (Vanek et al. 2014; Gan and Wong 2016), bridge-like scaffold (Dumas et al. 2014), and repetitive cellular structures (Strano et al. 2013; Hussein et al. 2013), which form lightweight support subjected to the well-defined part geometry and build direction.”
On utilizing topology optimization to design support structure to prevent residual stress induced build failure in laser powder bed metal additive manufacturing (2019, methodology): “[7] applied the lattice structure with very low volume fraction for the design of support structure for DMLS technique.”
Topology optimization of 3D self-supporting structures for additive manufacturing (2016, methodology): “Eﬀorts have been made to automate and/or optimize the addition of these support structures [15, 16, 17], or to ﬁnd the most economical sacriﬁcial lattice structures, e.g. [ 18].”
Metal additive manufacturing in the commercial aviation industry: A review (2019, background): “these structures must be used for anchoring the part to the substrate plate and minimize distortions due to the powder spreading [39, 40].”
