Title:
DISPENSING HEAD, THREE-DIMENSIONAL FABRICATION DEVICE, AND THREE-DIMENSIONAL FABRICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/121796
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a dispensing head with which a solid filament is stably fed even when a solid filament obtained from an elastomer material is used, the dispensing head therefore being able to stably discharge a thermally fused polymer material; as well as a three-dimensional fabrication device and three-dimensional fabrication method using said dispensing head. This dispensing head, which is used in a three-dimensional fabrication device for manufacturing three-dimensional shapes by thermal fusion lamination, is characterized in being provided with: a material-supplying means for supplying a solid filament obtained from a thermally-fusible polymer material; a heating means for thermally fusing the solid filament supplied by the material-supplying means; and a material-discharging means for discharging the fused polymer material obtained as a result of the solid filament being heated by the heating means.
