Abstract
Single-nozzle based multimaterial direct ink writing enables voxel-based fabrication with superior printing efficiency than multi-nozzle protocol. This is attractive for food 3D printing process where efficiency matters for its application. However, for single-nozzle based process, the presence of residual material in the shared channel can affect its printing fidelity. In this study, we propose a path planning algorithm that can address this issue by incorporating (i) advance distance to compensate the extrusion delay when switching materials, and (ii) in-process printhead motion adjustments to stabilise the extrusion process. Our approach demonstrated a substantial improvement in printing fidelity, where the switching point offset was reduced to ±0.5 mm. Similarly, the unstable extrusion behaviours (bulging and necking) during switching materials were suppressed, where the printing fidelity was improved by 27 ± 5% (bulging) and 19 ± 3% (necking) respectively. Additionally, we provide an open-source slicing programme that empowers users to implement the above two algorithms.
