Ultrasonic plasticizing fusion deposition forming 3D printing device

Abstract

The invention provides an ultrasonic plasticizing fusion deposition forming 3D printing device. The ultrasonic plasticizing fusion deposition forming 3D printing device comprises a support, a printing unit, a printing head unit used for transmitting fusion materials to the printing unit to be printed, and a material fusion unit. The support comprises a first work platform provided with the printing head unit and the material fusion unit and a second work platform provided with the printing unit. The material fusion unit comprises an ultrasonic system used for fusing materials, a ration device and a drive system used for driving the movement of an ultrasonic system. The ration device comprises a connecting rod, a left plate and a right plate. One end of the connecting rod is arranged in a cavity of the second base, and the other end of the connecting rod stretches out of the cavity and is connected with the ultrasonic system through a first connecting plate. The left plate is arranged in the cavity, and fixed to the end, arranged in the cavity, of the connecting rod. The right plate is arranged in the cavity corresponding to the left plate, a certain distance is formed between the right plate and the left plate, and the right plate is arranged on the connecting rod in a sleeving manner and can move along the connecting rod. The ultrasonic manner is adopted in the device for fusion, and the fusion speed is higher.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular, to a 3D printing device of ultrasonic plasticization fusion deposition modeling. Background technique [0002] In recent years, 3D printing technology has been used more and more to manufacture parts, and its technical characteristics of layer-by-layer manufacturing can make parts faster and more personalized than traditional manufacturing technology. This technology has a wide range of applications in the fields of weaponry, automobiles, medicine, and construction. However, due to limitations in machine size, materials, and costs, 3D printing technology is still in the development stage. [0003] At present, the raw materials for 3D printing mainly have three forms: filamentous, powdery, and granular. The corresponding 3D printing equipment has slightly different processing principles due to the different forms of materials. Among them, granular materials are new types of mate...

AI Technical Summary

Problems solved by technology

[0004]The working principle of 3D printers using filamentous materials is fused deposition technology. This kind of equipment has a relatively simple structure but low molding precision and relatively slow molding speed; The working principle of 3D printers with granular materials is powder solidification and sintering technology. This kind of equipment can manufacture complex components or molds, but the surface of the samples is rough and granular; The combined structure of the screw and the heating coil is specifically to set the heating coil at the feed inlet to melt the material, and then use the screw to rotate to shear and extrude the material to the nozzle. The structure is more complicated, and the processing accuracy is relatively high. However, the screw structure has two major disadvantages: 1. The diameter of the screw is relatively large: the screw can be obtained by processing a thread on a shaft, so the diameter cannot be made too small, otherwise it will break at the root of the tooth; 2. The material is easy to Deterioration: Since it takes a certain amount of time for the heating coil to melt the material, the material will stay in the barrel for a long time
