Meeting 2026 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2026)
Symposium 2026 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2026)
Presentation Title Design of Interlocking Joints for Multi-Material Interface Using Topology Optimization
Author(s) Myung Kyun Sung, Albert C To
On-Site Speaker (Planned) Myung Kyun Sung
Abstract Scope Traditional joining methods like adhesives, welding, and bolting often fail under environmental stress and lack versatility across diverse materials or geometries. Modern applications require resilient, rapidly fabricated joints for dissimilar materials that can survive extreme conditions. However, current techniques cannot precisely tune strength or failure modes through localized geometry. This study addresses this by using topology optimization to design mechanically interlocked interfaces for multi-material additive manufacturing. By accounting for interfacial weak points during the design process, this approach enables robust, assembly-free joining of dissimilar materials.
