Micro-nano three-dimensional printing nozzle device

Abstract

The invention discloses a micro-nano three-dimensional printing nozzle device. The three-dimensional printing nozzle device comprises a controller, a storage bin and a nozzle main body part. The nozzle main body part comprises three groups of spray orifice arrays with different diameters, and the spray orifice arrays are respectively an A group spray orifice array, a B group spray orifice array and a C group spray orifice array. The three groups of the spray orifice arrays with the different diameters are connected to three nozzles respectively. The controller comprises a central processing unit, a controller for the first spray orifice array, a controller for the second spray orifice array, a controller for the third spray orifice array and a driving power source. The central processing unit controls and switches working of the controller for the first spray orifice array, the controller for the second spray orifice array and the controller for the third spray orifice array by outputting different pulse signals. The controller for the first spray orifice array, the controller for the second spray orifice array and the controller for the third spray orifice array respectively control a working state of each spray orifice in each of the three groups of the spray orifice arrays with the different diameters. According to the three-dimensional printing nozzle device, rapid rough machining is performed by utilization of the work of the large-diameter spray orifices and slow finish machining is performed by utilization of small-diameter spray orifices, thus achieving macro-micro composited three-dimensional rapid moulding.

Description

technical field [0001] The invention is a micro-nano three-dimensional printing nozzle device, which belongs to the innovative technology of the micro-nano three-dimensional printing nozzle device. Background technique [0002] 3D printer is a process of rapid prototyping. It adopts layer-by-layer accumulation to produce 3D models. Its movement process is similar to that of traditional printers, except that traditional printers spray ink onto paper media to form two-dimensional graphics. The three-dimensional printer is to spray liquid photosensitive resin materials, molten plastic filaments, gypsum powder and other materials through the nozzle to achieve layer-by-layer accumulation and superimposition to form a three-dimensional entity. At present, the nozzles of 3D printers at home and abroad are all designed with two-dimensional structures, and the diameters of the nozzle holes are all of a single size. [1] . [0003] In the mid-1980s, SLS was developed and patented by ...
