ABSTRACT / САЖЕТАК:

This paper investigates the mechanical properties of bonded joints made of components manufactured using Selective Laser Melting (SLM), an additive manufacturing (AM) technique that enables the production of complex metal parts with high precision. In multi-part assemblies, adhesive bonding is often employed, placing demands on the strength and durability of the joints. In this study, maraging steel samples fabricated by SLM were joined using two types of epoxy adhesives. The mechanical performance of the joints was evaluated through double-lap shear tests in accordance with ASTM D3528. The aim of the research was to determine the influence of the additively manufactured structure, surface condition, and adhesive type on the strength of the bonded joints.
