Three-dimensional printing device with injector head capable of being vibrated

Abstract

The invention relates to a three-dimensional printing device with an injector head capable of being vibrated. The device comprises a control system, a screw type extrusion system (or wire feeder), the injector head, a workbench and a workbench moving system. The injector head is connected to the lower end of the screw type extrusion system (or wire feeder) and made communicated with a discharge outlet of the screw type extrusion system (or wire feeder). The screw type extrusion system (or wire feeder) conveys materials to the injector head. The screw type extrusion system (or wire feeder) and the injector head are connected into a whole and can do X-axis and Y-axis direction horizontal movement above the workbench. The workbench moving system drives the workbench to do up-down vertical movement. The control system controls movement of the whole system, and therefore three-dimensional printing is completed. The three-dimensional printing device is characterized in that an ultrasonic vibration device is installed in the injector head. The three-dimensional printing device has the advantages that the structure is simple, molded products are large in density, tensile and impact strength is improved, and product quality is good.

Description

technical field [0001] The invention relates to a 3D printing device, in particular to a 3D printing device with a vibrating ejection head. Background technique [0002] The basic principle of 3D printing processing and forming is: first establish a three-dimensional computer model of the part, then slice it layer by layer, obtain the information data of each layer, and perform layer-by-layer superimposed manufacturing on this basis. This manufacturing method has many advantages due to its own It is widely used in various industries due to its advantages. [0003] Material extrusion 3D printing device and pneumatic powder flow 3D printing device are two common 3D molding equipment; among them, the material extrusion type belongs to the fusion deposition forming method, and the pneumatic powder flow type belongs to the directed energy deposition type additive However, whether it is fused deposition or directed energy deposition, there are disadvantages, that is, the structur...

[0003] Material extrusion 3D printing device and pneumatic powder flow 3D printing device are two common 3D molding equipment; among them, the material extrusion type belongs to the fusion deposition forming method, and the pneumatic powder flow type belongs to the directed energy deposition type additive However, whether it is fused deposition or directed energy deposition, there are disadvantages, that is, the structure of 3D printed parts is loose, the product is not compact, and the mechanical properties are poor; in view of such problems, some researchers will Vibration is introduced into this kind of directional energy deposition processing of 3D printing. The vibration method includes the vibration of the substrate and the vibration of the powder application mechanism. Although these two methods can partially overcome some of the original problems, the structure is relatively complicated. In the material extrusion 3D printing equipment, there is no patent to improve the quality of molded parts by applying vibration.
