Abstract—
A device has been developed to study the physicochemical processes of the formation of a structure that occurs during temperature-induced aggregate transitions of liquid and gel compositions during three-dimensional printing under conditions of significant temperature gradients. The device is based on a three-dimensional coordinate system with a heated pneumatic dispenser of viscous fluid compositions and a substrate cooled to −190°C. Liquid nitrogen, solid carbon dioxide, or an integrated Peltier cooling system are used to cool the substrate. The device is equipped for contact temperature control and has a digital video camera.
