Adhesive Bonding of Elements Made Using the Multi Jet Fusion Additive Technique

Abstract

: The research discussed the application potential of adhesive bonding in the joining of 3D printed structures made using the Multi Jet Fusion (MJF) state-of-the-art additive technology (HP). The research involved the performance of technological tests aimed to assess the adhesive properties of 3D printout surfaces in the function of a surface layer treatment method as well as to evaluate adhesives used in the joining of 3D printed structures. The tests performed within the research included roughness measurements, contact (wetting) angle measurements, peel strength tests, shear strength tests and bend tests. The results obtained in the tests made it possible to assess the joinability of MJF printouts as well as to identify reasons for problems accompanying the joining of such elements.
