The Mechanical Performance of Additive Manufactured Silica Lattice Structures

The current study investigates the performance of Additive Manufactured (AM) silica (SiO2) scaffolds using advanced lattice designs. In particular, six specific design structures based on Strut-Lattice Structures and Triply Periodic Minimal (TPMS) were additively manufactured by utilising Stereolithography method. Initially, mechanical morphological behaviour solid 3D printed specimens was studied characterization techniques, such as instrumented nanoindentation Scanning Electron Microscopy (SEM) in order to understand material behaviour. Then, AM complex tested under a quasi-static uniaxial compression loading reveal their response, which is depended relative density also deduce stress strain response. results have shown that all presented extensive degradation due influence scaling laws existing porosity structure originated from manufacturing procedure. However, strut-structures exhibited more severe deterioration properties compared with TPMS structures. This ceramic an essential step prior further exploration research tissue engineering.
