Abstract Scope Wave springs perform better than helical springs in terms of mechanical performance. This study aims to use additive manufacturing (AM) to design and fabricate wave springs with interconnecting waves. Compared to uniformly shaped and dimension wave springs, intricate and variable dimension wave springs are only possible through AM because of the design flexibility. The performance of interconnecting wave springs is better regarding load-bearing, stiffness, energy absorption, and energy release. Several design configurations with varied and uniform dimensions were developed and fabricated using AM while ensuring constant mass and height for all designs. Compression tests were performed to study the stiffness, energy absorption, load-bearing capability, and energy loss. The findings showed that contact wave springs with higher stiffness absorbed more energy. The taper-wave spring was the optimum design for load-bearing and had the largest energy loss capacity. The results were also validated by finite element analysis for all the designs.
