Its appeal is attributed to accelerated prototyping, improved sustainability, and the capacity to fabricate intricate shapes. Nonetheless, the size constraints of additive manufacturing components require the assembly of smaller 3D-printed elements to create larger structures. This study investigates the tensile properties of scarf joints (SJs) created from several polymers, including ABS, PETG, and PLA, adhered with Araldite\u00ae 2015 and Sikaforce\u00ae 7752 adhesives. The characteristics of the adherends were assessed prior to examining the adhesive efficacy in the SJ configuration. Experimental evaluations quantified failure modes, joint strength, assembly stiffness, and energy at failure, comparing findings with predictions from a cohesive zone model (CZM). The objective was to determine the ideal combination of materials and adhesives for enhanced joint performance. Results indicated that joint performance is greatly affected by the adherend material, adhesive selection, and scarf angle. PLA and Araldite\u00ae 2015 typically exhibited optimal strength and stiffness, but Sikaforce\u00ae 7752 demonstrated enhanced energy absorption for extended bonding lengths.<\/jats:p>","DOI":"10.3390\/jmmp9040115","type":"journal-article","created":{"date-parts":[[2025,4,2]],"date-time":"2025-04-02T04:06:05Z","timestamp":1743566765000},"page":"115","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Scarf Adhesive Bonding of 3D-Printed Polymer Structures"],"prefix":"10.3390","volume":"9","author":[{"given":"Tiago F.
