Relation between printed fibre diameter, nozzle translation speed and temperature for the carbohydrate glass and sugar glass fibres printed with a 0.15 mm nozzle. (a) setup to determine fibre diameter with two printed carbohydrate fibres suspended on top of the pre-printed framework, scale bar 1000 µm; (b) Detailed image of the carbohydrate fibre connection with the framework, showing some degree of necking at the beginning of the fibre, scale bar 100 µm; (c) Fibre diameter for the carbohydrate glass at different temperatures and translation speeds; (d) Fibre diameter for the sugar glass at 90 °C, showing the effect of lower viscosity on printing behaviour and quality. The fitted function is Equation (1) for glass fibre drawing with Q as the fitting parameter, with values given in Table 2.
