APPARATUS AND METHOD OF PRINTING

摘要

A printing apparatus and a printing method are provided to prevent generation of a void by preventing hardening of a printing solution through a heater. A printing apparatus includes a chamber(11), a piston(13), and a heater. The chamber is made of high thermal conductive metal material. The chamber receives a printing solution(24). A nozzle(12) is formed in one side of the chamber. A whole part or a part of a side wall of the chamber is tilted toward a nozzle direction. The piston provides pressure to an inner part of the chamber. The heater provides a heat to the printing solution. The heater is a coil(14). The coil is built in a side wall of the chamber. The coil delivers the heat to the printing solution through the side wall of the chamber in order to prevent hardening of the printing solution.
