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

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable three-dimensional printer capable of performing a good modeling operation. SOLUTION: A hot end for heating, melting and discharging a filament-shaped modeling material, a feeding means for supplying the filament-shaped modeling material to the hot end, and a control means for controlling heating of the filament-shaped modeling material. In a 3D printer equipped with, the hot end is a supply unit having a supply port to which the modeling material is supplied, a discharge unit having a discharge port for discharging the modeling material, a passage connecting the supply port and the discharge port, and The control means has a melting part that melts the supplied filamentous molding material, and the control means stops the supply of electric power to the heating means when the temperature of the melting part exceeds the upper limit of a predetermined temperature range and falls below the lower limit. And the control to restart the supply of electric power to the heating means, and the control to supply electric power to the heating means substantially in synchronization with the start of supply of the filament-shaped molding material by the feeding means. It is a feature. [Selection diagram] Fig. 1
