Dual-caliber variable flow type 3D printer extruding opening

Abstract

The invention discloses a dual-caliber variable flow type 3D printer extruding opening. The dual-caliber variable flow type 3D printer extruding opening comprises a material guiding mechanism, a driving mechanism, a heating mechanism and a storing mechanism. The storing mechanism is provided with an inner cavity, and the inner cavity stores consumables used for printing workpieces. The discharging end at the bottom of the storing mechanism is connected with the feeding end on the upper part of the material guiding mechanism. The material guiding mechanism is used for extruding the consumables from the storing mechanism to a printing working face located below the discharging end of the material guiding mechanism. The middle of the material guiding mechanism is provided with the heating mechanism used for providing a heat source required for melting consumables. The material guiding mechanism further comprises a control mechanism and a guiding mechanism. The control mechanism is installed at the bottom of the material guiding mechanism, and is used for controlling an extruding caliber and extruding flow of the consumables. The guiding mechanism is arranged in the middle of the material guiding mechanism. The guiding end of the guiding mechanism is connected with the output end of the driving mechanism, and the guiding end of the guiding mechanism is driven by the output end of the driving mechanism to move in the material guiding direction.

Description

technical field [0001] The invention relates to an extrusion port of a 3D printer, in particular to a dual-caliber, variable flow type 3D printer extrusion port. Background technique [0002] 3D printer is a kind of accumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials to print layer by layer. Bonding materials to create three-dimensional objects. At present, 3D printers use layer-by-layer printing to form and manufacture products. [0003] The extrusion port of the 3D printer is used to extrude the adhesive material from the storage chamber to the printing work surface. Most of the existing printers have a fixed diameter and the amount of adhesive material extruded from the extrusion port per unit time is a fixed value. The defect is that when the production requires different printing accuracy, the diameter of the extrusion po...

Problems solved by technology

[0003] The extrusion port of the 3D printer is used to extrude the adhesive material from the storage chamber to the printing work surface. Most of the existing printers have a fixed diameter and the amount of adhesive material extruded from the extrusion port per unit time is a fixed value. The defect is that when the production requires different printing accuracy, the diameter of the extrusion port and the extrusion volume cannot be changed accordingly, that is, when the precision requirement is high, the fixed diameter cannot meet the production accuracy requirements, and when the precision requirement is low, the fixed diameter The extrusion volume is small and the printing efficiency is low
