Triply Periodic Minimal Surface (TPMS) structures fabricated via Additive Manufacturing (AM) have recently emerged as being appropriate candidates for high-value engineered structures, including porous bio-implants and energy absorbing structures. Among the many TPMS designs, Gyroid demonstrated merits in AM manufacturability, mechanical properties, permeability comparison to traditional lattice are mathematically formulated by geometric factors: surface thickness, sample size, number of...
Triply periodic minimal surfaces (TPMS) present a starting point for designing infinitely many novel cellular solids, creating the need structured approach to their design and evaluation. In this study space is formalised using set of input parameters evaluation metrics provide reproducible TPMS-like solids. Interactions between are identified full-factorial experiments. From most impactful as TPMS equation, type structure, volume fraction. It was found that gyroid-surface structure provided...
The gyroid has been identified as a cellular topology suitable for engineering applications and, particularly in its solid-network form, biomedical applications. Its solid-surface form received less attention but offers additional benefits of continuous surface that partitions space and provides large area heat transfer or cell attachment. Through numerical methods it is shown the first time under uniaxial loading distributes loads predominantly within helical substructures. Furthermore, by...
Implicitly defined structures such as triply periodic minimal surfaces (TPMS) have potential applications in science, technology, engineering, arts and mathematics. TPMS Designer is a tool for rapidly generating, visualizing analyzing implicitly structures. The software allows users to parametrically modify the size, aspect ratio, rotation, resolution of structure. Cellular volume fraction can be adjusted using surface type isovalue options. includes tools importing exporting traditional...
Many naturally occurring materials exhibit repeating hierarchical structures, comprising of multiple constituent that combine to form a composite material. In this work an additive manufacturing technology known as Material Jetting is used fabricate co-continuous multi-material structures. The structures are produced using two with distinctly different mechanical properties at variety proportions. design experiments was developed based on triply periodic minimal surface the Gyroid, allowing...
