The Influence of Coating and Adhesive Layers on the Mechanical Performance of Additively Manufactured Aluminum–Polymer Hybrid Joints

AddJoining technique has been recently introduced to produce metal–polymer composite hybrid layered structures. The methodology combines the principles of joining and polymeric additive manufacturing. This paper presents three process-variants investigated demonstrated for material combination aluminum 2024-T3 acrylonitrile butadiene styrene form single lap joints. microstructure mechanical performance were assessed. process variant using heating control showed ultimate shear force 1.2 ± 0.05 kN displacement at a break 1.21 0.16 mm as result strong bonding formation interface For instance, other two variants tested (with epoxy adhesive, with thin-acrylonitrile (ABS) coating layer applied on metal) presented reduced in comparison control, namely approximately 42% 8.3%, respectively. former had mixed adhesive–cohesive failure due lower between adhesive ABS printed layers. latter displayed slight decrease heat-control specimens. could be explained by presence micro-voids formed solvent evaporation during AddJoining.
