An extruded 3D printing device and method capable of realizing z-axis high-precision control

Abstract

The invention discloses an extruding 3D printing device and method capable of realizing Z-axis high-precision control. Plate, X-axis bracket, X-axis conveyor belt, left Z-axis motor, Y-axis motor, X-axis motor, stocker bracket, stocker, left upper limiter, driven guide rail, extrusion motor, Y-axis conveyor belt , the frame, the driven mechanism bracket, and the driven mechanism wheel are connected in sequence from top to bottom to form a whole. When one layer is processed, the workbench automatically rises up one layer according to the parameters to process the next layer. When the last layer is processed, the machine stops working. At this time, the parts are completed and the parts stop on the liquid material. The equipment can process three-dimensional entities with high dimensional accuracy and complex internal structure. It can quickly produce new product prototypes in the research and development stage, shorten the product development cycle, and has the advantages of low cost and large processable volume.

Description

technical field [0001] The invention belongs to the technical field of 3D micro-nano processing, and specifically relates to an extrusion-type 3D printing fast device and method capable of realizing Z-axis high-precision control. Background technique [0002] With the rapid development of 3D printing and micro-nano processing technology, in order to meet the needs 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 applied them in various fields and industries. industry. 3D printing or Rapid Prototyping (RP) technology is an additive manufacturing technology based on the idea of ​​discrete accumulation, a "bottom-up" material additive manufacturing method. Through computer-aided design technology, materials are connected and stacked layer by layer according to the three-dimensional digital model of the part, so as to manufacture solid parts. The...

Problems solved by technology

[0004] At present, most extrusion-type 3D printing equipment use air pump as the driving energy. The advantage of this method is that the printing process can be controlled by controlling the opening and closing of the air pump. The disadvantage is that the printing accuracy is low, and it is difficult to achieve high-precision control.
