Development of ice 3D printer applying supercooling phenomenon

抄録

Undercooling state is metastable and immediately releasable by applying disturbance intentionally. Therefore, a 3D printer with considerably high modeling efficiency expectedly can be realized by using the supercooling phenomenon. This study discussed the applicability of the supercooling phenomenon in ice (H₂O) to additive manufacturing. As a result, freezing of the supercooling phenomenon due to impact was observed. The freezing behavior depended on the flow rate, and freezing in the syringe was observed when the flow rate was high. In addition, when the conditions such as the amount of water droplet was adjusted, it was possible to fabricate shapes with simple structures by stacking.
