3D printer, 3D printer module device, and 3D modeling method

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable three dimensional printer.;SOLUTION: A three dimensional printer includes: a hot end that heats, melts and discharges a molding material; feeding means for supplying the molding material to the hot end; and control means for controlling a heating of the molding material. The hot end includes: a supply unit having a supply port to which the molding material is supplied; a discharge part having a discharge port that discharges the melted molding material; a passage connecting the supply port and the discharge port; and a melting part to which heating means is attached to melt the molding material. The control means makes it possible to execute a control to supply a predetermined amount of electric power to the heating means in order to maintain a molten state of the molding material in the melting part while a supply of the molding material by the feeding means is temporarily stopped, and a control to supply electric power larger than the predetermined amount to the heating means substantially in synchronization with the feeding means restarting the supply of the molding material.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2021,JPO&INPIT
