Embodiment 1

[0024] Embodiment 1, the molding system used in the embodiment of the present invention is a full-area three-dimensional molding system with eight orifice units, and its structure is as follows image 3 As indicated, the three-dimensional diagram is as Figure 4 shown. The full-area forming system with eight orifices uses three rings of print head brackets, each of which can rotate freely at 360 degrees, and eight printing orifice units are placed in each ring, a total of twenty-four printing orifice units. According to the finite element analysis of the model, the model cloud image of eight gray colors is obtained, and the eight colors are rendered on the original model, and one color is defined to correspond to one material, so that the eight printing nozzle unit pairs correspond to eight printing shapes Materials, which correspond to seven printing and forming materials, and one printing and forming support material. The eight material boxes are divided into eight colors,...

Abstract

The invention discloses a full-area three-dimensional molding manufacturing system. According to the system, finite element analysis is firstly carried out on a three-dimensional model, and then parallel continuous molding of multiple materials is carried out through the full-area three-dimensional molding manufacturing system. Through the automatic material selecting and combining function of the molding manufacturing system, any multiple printing molding materials are freely combined, and wide materials are provided for the three-dimensional molding system. According to the full-area three-dimensional molding system, multiple materials of the model can be printed at the same time, any multiple materials can be freely and adjacently connected, molding time is short, and molding precision is high. Therefore, the mold has a few material compositions and is high in strength, and the functional or semi-functional model requirement can be met.

Description

technical field [0001] The invention relates to a manufacturing system device for a three-dimensional forming model with a full-area printing nozzle structure, and belongs to the technical field of rapid prototyping micromechanical three-dimensional processing. Background technique [0002] Three-dimensional forming (Rapid Prototyping and Manufacturing) technology is a high-tech developed in the late 1980s. It integrates computer-aided design and computer-aided manufacturing with the help of modern means such as computer, laser, precision transmission and numerical control. According to the CAD three-dimensional model constructed on the computer, the model is discretized into a series of ordered units according to certain rules, and the forming system makes a series of layers and automatically connects them to obtain a three-dimensional physical entity. [0003] Since the emergence of 3D rapid prototyping technology in the late 1980s, dozens of processes have appeared. At ...
