Ceramic accumulated forming precision adjustable three-dimensional forming printing machine

Abstract

The invention discloses a ceramic accumulated forming precision adjustable three-dimensional forming printing machine. The ceramic accumulated forming precision adjustable three-dimensional forming printing machine comprises a material guiding mechanism, a drive mechanism, a heating mechanism and a storage mechanism. The storage mechanism is provided with an inner cavity, and consumables for printing workpieces are stored in the inner cavity. The bottom discharging end of the storage mechanism is connected with the feeding end of the upper portion of the material guiding mechanism. The material guiding mechanism is used for extruding the consumables to the printing work face through the storage mechanism, wherein the printing work face is located below the discharging end of the material guiding mechanism. The middle portion of the material guiding mechanism is provided with the heating mechanism for providing a heat source needed for consumable fusion. The heating mechanism is externally in cup joint with a discharging pipe and can heat the consumables in the discharging pipe. The ceramic accumulated forming precision adjustable three-dimensional forming printing machine has the functions that the diameter of an extruding port is adjustable, and the extruding flow is adjustable; in the process that a material limiting block gets away from the outer wall of the extruding port,the extruding radius is changed into the extruding port radius of the extruding port outer wall from the radius of a second material guiding hole, and the functions that the extruding radius is increased, and the extruding amount is large are achieved.

Description

[0001] This invention is a divisional application for an invention patent with the application date of July 27, 2017, the application number: 2017106265283, and the invention title of "a dual-caliber, variable-flow 3D printer extrusion port". technical field [0002] The invention relates to an extrusion port of a 3D printer, in particular to a precision-adjustable three-dimensional forming printer for accumulative forming of ceramics. Background technique [0003] 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. [0004] The extrusion port of the 3D printer is used to extrude the adhesive material from the storage chamber to the printing...

AI Technical Summary

Problems solved by technology

[0004] 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
