Patent ID: 10759162

Abstract:
A printing head module for a 3-D printing apparatus includes a 3-D print head, an ink-jet print head and a baking module. The 3-D print head includes a melting module and a base-material nozzle to print a plurality of staking layers. The ink-jet print head is connected to the 3-D print head and includes an ink nozzle to dispense ink on each stacking layer. The baking module is disposed between the 3-D print head and the ink-jet print head and includes a fan, a discharge casing and a heating module. The fan includes an air-discharge side facing the base to provide an air flow. The discharge casing is disposed on the air-discharge side. The heating module is disposed between the fan and the discharge casing to heat the air flow and the heated air flow being blown out via the discharge casing for drying the ink layer.
