Multi-Axis Support-Free Printing of Freeform Parts with Lattice Infill Structures

30 Jun 2020 Li Yamin Tang Kai He Dong Wang Xiangyu

In additive manufacturing, infill structures are commonly used to reduce the weight and cost of a solid part. Currently, most infill structure generation methods are based on the conventional 2.5-axis printing configuration, which, although able to satisfy the self-supporting condition on the infills, suffer from the well-known stair-case effect on the finished surface and the need of extensive support for overhang features...
