Description
Technical Field

Background
With the rapid development of 3D printing and micro-nano processing technologies, in order to meet the requirements of different fields and industries, researchers at home and abroad have developed various types of micro-nano scale 3D printing processes and printing materials in recent years, and the printing materials are applied to various fields and industries. The 3D printing, namely Rapid Prototyping (RP) technology is an additive manufacturing technology based on the idea of discrete build-up, a "bottom-up" additive manufacturing method of materials. And (3) connecting and stacking the materials layer by layer according to the three-dimensional digital model of the part by a computer aided design technology, thereby manufacturing the solid part. The manufacturing process is reduced from complex three-dimensional processing to a series of simple two-dimensional layer sheet processing, and the processing difficulty of the two-dimensional layer sheet is basically irrelevant to the complexity of the solid structure of the part, so that the processing difficulty of the solid body of the part is greatly reduced, and three-dimensional solid models with different shapes and structures can be completed by a uniform and automatic method, so that the 3D printing technology has the advantages of no material waste compared with the traditional processing technology, free structure design of products can be realized, the processing period is short, and the effects of energy conservation and environmental protection are achieved.
Extrusion 3D printing, also known as Fused Deposition Modeling (FDM), is a process that uses continuous filaments of thermoplastic material for 3D printing. The wire is fed from a coil through a moving printer heated extrusion head and deposited on an ever-growing work surface. The print head is moved under computer control to print out the desired shape. Typically, the head is moved in two dimensions, one horizontal plane at a time, and then the print head is moved vertically a small distance to process a new layer. Printing can be stopped and started by controlling the speed of the extrusion head to form an interrupted plane without cascading or balling between planes. Extrusion 3D printing is now the most widely used 3D printing process on the market. Other techniques, such as photopolymerization and powder sintering, may provide better results, but their cost is much higher.
Most of present extrusion formula 3D printing apparatus all adopt the air pump as the drive energy, and this mode advantage is that the process of accessible control air pump is opened and close and is controlled printing, and the shortcoming is that the printing precision is lower, is difficult to accomplish high accuracy control. The device for solving the problem adopts a unique mechanical structure, improves the product precision, and simultaneously can reduce the occupied space, reduce the noise pollution and the like.
This product passes through the motion of control mechanism top extrusion platform motor, extrudes the printing material in the heating material stock pipe, simultaneously, in order to solve the material accident that probably causes when printing apparatus Z axle removes and extrude, will control the motor that the Z axle removed and extrude the motor operation of platform and carry out synchro control through control system: when the equipment needs to move in the Z-axis direction, the two motors are controlled to synchronously operate, so that the material in the material storage pipe is prevented from being extruded due to distance change; when the equipment needs to print, the Z-axis control motor is locked, the extrusion platform motor operates independently, and materials are extruded.
