Abstract
Official abstract text for this publication.
A 3-dimensional printing apparatus may include a storage unit, a dispensing unit, and a pressure control unit. The storage unit stores a printing material satisfying Bingham plastic model in which a viscosity is decreased as a pressure is increased. The dispensing unit receives the printing material from the storage unit to ejaculate the printing material. The pressure control unit controls a pressure applied to the printing material supplied in the dispensing unit to control a viscosity of the printing material. Thus, a product having soft characteristics may be manufactured.
First claim
Opening claim text (preview).
What is claimed is: 1 . A 3-dimensional printing apparatus comprising: a storage unit storing a printing material satisfying Bingham plastic model in which a viscosity is decreased as a pressure is increased; a dispensing unit receiving the printing material from the storage unit to ejaculate the printing material; and a pressure control unit controlling a pressure applied to the printing material supplied in the dispensing unit to control a viscosity of the printing material. 2 . The 3-dimensional printing apparatus of claim 1 , further comprising a temperature control unit controlling a temperature of the printing material supplied in the dispensing unit so that the printing material has a phase in which solid and liquid coexists. 3 . The 3-dimensional printing apparatus of claim 1 , wherein the printing material maintains s semi-solid state in the dispensing unit. 4 . The 3-dimensional printing apparatus of claim 1 , wherein the printing material has a gel state in which liquid and solid powder are mixed. 5 . The 3-dimensional printing apparatus of claim 4 , wherein the solid powder includes silicon oxide or metal oxide.
