Abstract

The extreme customisation and rapid prototyping capabilities of the 3D printing process allows the manufacture of low-cost and patient-specific radiotherapy phantoms for quality assurance purposes. However, the associated printing techniques and materials are experimentally limited and are yet to be quantified in terms of manufacturability. In addition to this, there lacks research in utilising naturally inspired structures, known as triply periodic minimal surfaces (TPMS), as a structural manufacturing basis for these phantoms, enabling material heterogeneity, which is a significant factor in attaining patient-specificity. We propose the use of Gyroid structures for radiotherapy phantom app..
