SLM 3D printed lattice structures for mechanical interlocking of metal and resin for high interface bonding strength
This data set is a part of a study in which various struts-based lattice structure has been designed over a stainless steel (SUS 316L) substrate for 3D-printing by SLM process, so as to create resin-metal bond at the interface during the plastic injection molding process. In this study, different lattice structures were first designed in a CAD environment and the strength of the subsequent lattice-resin interlock was predicted using the Finite Element Analysis (FEA) method. The numerical model for FEA simulation was generated in the ABAQUS/CAE 2020 Standard solver. The test samples were fabricated using SLM and injection molding process. Individual stress status of lattice and resin during tensile test in the Instron 5967 tensile testing machine were investigated to determine the failure strength of lattice-resin interlock. The Charts in this dataset include the pull force data for each of the designed lattice structure acquired by FEA simulation. The charts also include the raw data of the failure stress of all the tested samples.
