Three-dimensional (3D) rapid forming printing system and method

Abstract

The invention relates to the field of rapid prototyping and discloses a three-dimensional (3D) rapid forming printing system. The system comprises a personal computer (PC) end with a control unit, an extruder, a printing base plate with a heating function, a servo motor which controls motion of the printing base plate, and a motion control unit, wherein the extruder is positioned above the printing base plate on the top of a body operating area; the servo motor and the printing base plate are positioned below the extruder at the bottom of the body operating area; the motion control unit is an embedded chip group; each chip comprises a task module for executing a control task; the motion control unit is positioned in a chip group slot below the body operating area; the extruder, the servo motor and the printing base plate are respectively and electrically connected with the motion control unit; the motion control unit is electrically connected with the PC end. By virtue of an incremental manufacturing method, namely models are established on the printing base plate layer by layer, rapid manufacturing is realized, processing of any model can be finished, and the system has certain application value and application prospects and can be applied to household and industrial production.

Description

technical field [0001] The invention relates to the field of rapid prototype manufacturing, in particular to a 3D rapid prototyping printing system and method, which realizes rapid and seamless manufacturing of any computer-side 3D model. Background technique [0002] 3D printers, English "3D Printers", the name of 3D printing is a new word that has appeared for the civilian market in recent years. It is a popular name. In fact, it has other academic names in the professional field "rapid prototyping technology" (and " Rapid Prototyping Technology", "Incremental Manufacturing Technology", "Additive Manufacturing Technology"). [0003] Rapid prototyping technology (also known as rapid prototyping manufacturing technology Rapid Prototyping Manufacturing, referred to as RPM), born in the late 1980s, is a high-tech manufacturing technology based on the material accumulation method. The machine tool can create any shape. According to the three-dimensional model data of the par...

Problems solved by technology

[0005] In the current printer technology, the stepper motors that control the movement of the printer in the X, Y, and Z directions only have control signals, which cannot guarantee the positional accuracy of the stepper motor movement. Therefore, during the printing process, a certain printing layer is prone to position errors, resulting in 3D The size of the model is not accurate enough, and the 3D model and the printing plate are prone to relative movement, which may cause printing errors
