Problems solved by technology

The consumables used in the existing FDM technology are filamentous materials, and ordinary industrial raw materials cannot be directly used, so the production cost is high
In addition, due to the limitation of filamentary materials, it is difficult to realize the diversity of materials. Also due to the limitation of filamentous materials, the pressure of material extrusion is directly provided by the material filaments, and it is difficult to achieve high-pressure rapid injection, which is not conducive to the processing of large objects. fast print

Abstract

The invention discloses a printing head for a 3D printer. The printing head comprises a shell, wherein a feeding device is vertically slipped in the shell; a pressure device is arranged above the feeding device; an outlet of the feeding device is communicated with a nozzle through a volume metering pump; the feeding device comprises a driving device, and a screw rod driven by the driving device to rotate; a feeding port is formed surrounding the upper side of the shell of the screw rod; a hot melting cavity is formed surrounding the lower side of the shell of the screw rod; and a one-way valve is sleeved at the tail end of the screw rod. The printing head for the 3D printer has the advantages of use of multiple raw materials as printing materials, low cost and high printing preciseness.

Description

technical field [0001] The invention relates to a printing device, in particular to a printing head for a 3D printer which can use various raw materials as printing materials, has low cost and high printing precision. Background technique [0002] 3D printing technology is a rapid prototyping technology, which is based on digital model files, using metal, plastic, inorganic materials, etc., to construct objects by layer-by-layer printing. At present, the 3D printing technology that uses plastic as the consumable mostly adopts the fused deposition method (FDM technology), that is, after the filamentous hot-melt material is melted, it is extruded through a nozzle and deposited on a platform, and finally formed by layer-by-layer accumulation of materials. object. The consumables used in the existing FDM technology are filamentous materials, and ordinary industrial raw materials cannot be directly used, so the production cost is high. In addition, due to the limitation of fila...
