ABSTRACT:
A 3-dimensional air bubble trapping apparatus includes a plurality of chambers, each having an inflow and outflow channel at both ends, and which traps air bubbles in a material introduced through the inflow channel, wherein the chambers are divided into a previous chamber and a next chamber based on a moving direction of the material in the chamber, and wherein the outflow channel of the previous chamber is connected to the inflow channel of the next chamber, and wherein a face perpendicular to an outflow direction of the material in the outflow channel of the previous chamber is not disposed parallel with a face perpendicular to the outflow direction of the material in the outflow channel of the next chamber, whereby air bubbles in the material are trapped without being affected by an angle defined by a gravity direction and vibration of the apparatus.
