Abstract Scope |
Epoxies are high-performance thermoset polymers with good mechanical strength, thermal, and electrical resistance, making them suitable for a wide range of structural applications. Additive manufacturing has the potential to design and manufacture lightweight lattice objects, but epoxy resins require expensive setups and require proprietary resins that can be difficult to manipulate. Here we use Freeform Reversible Embedding (FRE) 3D printing process to print off-the-shelf epoxy polymers to fabricate robust lightweight lattice structures with enhanced load-bearing capacities. We characterize individual filament morphologies of planar and non-planar printed filaments and then characterize the mechanical behavior of non-planar printed lattice geometries using compression testing and compare it with a finite element model (FEM). This technique has enabled us to print high-strength materials into non-planar geometries previously challenging to achieve through conventional additive manufacturing practices. |
