The Effects of Post-Processing and Geometric Parameters on the Compressive Strength of Additively Manufactured Resin Lattice Structures
Compressive strength is a crucial property in load-bearing design, yet the combined effects of post-processing and geometry on resin-based lattice structures remain underexplored. This study investigates how these parameters influence the compressive strength of SLA-printed resin lattices. Using exp...

| description | Compressive strength is a crucial property in load-bearing design, yet the combined effects of post-processing and geometry on resin-based lattice structures remain underexplored. This study investigates how these parameters influence the compressive strength of SLA-printed resin lattices. Using experimental testing and Bayesian Optimization, I examined the impact of cure time, cure temperature, wash time, pre-cure time, edge length, strut diameter, and relative density on mechanical performance. Fifty octet-truss lattices were fabricated and tested under static compression to measure stress, strain, and Young’s modulus. Results show that relative density is the strongest predictor of compressive strength. Longer cure times, shorter wash and pre-cure times, and smaller edge lengths significantly improve structural performance. These findings offer a holistic view of how post-processing and design choices impact mechanical behaviour, and they provide predictive models to help researchers optimize lattice structures for specific performance goals in additive manufacturing applications.
