Abstract
SummaryApart from the material compositions, processing parameters of a 3D printer also affect the modelling effect of printed samples. This paper presents the influence of processing parameters including filament diameter (2.10, 2.30, 2.50 mm), nozzle movement speed (20, 25, 30 mm/s), nozzle diameter (0.8, 1.5, 2.0 mm) and nozzle height (2.10, 2.40, 2.60 mm), as well as that of post‐process fast‐cooling (−65 °C; 0, 5, 10 min), on the rheological properties and geometric accuracy of a 3D‐printed food construct made of baking dough (BD). Results showed that the printed object whose shape best matched the target geometry could be obtained with the following processing parameters: filament diameter of 2.30 mm, nozzle movement speed of 25 mm/s, nozzle diameter of 2.0 mm and nozzle height of 2.40 mm during 3D printing, combined with fast‐cooling at −65 °C for more than 10 min after printing and before baking.
