Joining technology of additively manufactured components: effects on the bonding strength for the adhesive application through inner channels

Abstract The maximum size of additively manufactured (AM) components is restricted due to the confined building space manufacturing machines. Component separation and subsequent joining can be an effective way larger using AM processes. For components, adhesive bonding provides great potential for not constraining adherend’s geometry, as long still applied surfaces adherends. This work investigates effectiveness applicability inner channels improve application. A circular single lap joint between a laser-based powder bed fusion (PBF-LB) component made AlSi10Mg cold drawn aluminum round bar was considered. PBF-LB were designed with varying geometric complexity implement different application concepts. Subsequently, bonded joints subjected static tensile tests. fracture strength where by injection into exceeds injected geometries manufacturable subtractive machining, also pre-applied.
