SUMMARY:

The use of lattice geometries in lightweight structural components offers numerous advantages, including superior load-carrying capacity, enhanced energy absorption, and design flexibility. This study presents a preliminary investigation into the mechanical properties of pyramidal lattice structures constructed from bamboo elements. The structures are assembled by connecting bamboo sticks with 3D-printed joints produced using fused deposition manufacturing with PLA and PETG polymers. To ensure secure attachment of the sticks and joints, a castor-oil biobased polymer is employed as the bonding phase. The mechanical properties of the pyramidal lattice structures are characterised through compression and three-point bending tests. The results demonstrate that these sustainable lattice structures exhibit an impressive loading capacity, with the ability to withstand up to 546 N under compression and approximately 90 N under bending. These findings suggest their potential for use as structural components, such as the core material of sandwich structures.
