Manufacturing method of grid combined type graphic model based on magnetic principle

Abstract

The invention discloses a manufacturing method of a grid combined type graphic model based on a magnetic principle. The manufacturing method comprises the following steps: carrying out 3D modeling ona basic unit geometry; according to the model data, enabling the basic geometry to be subjected to 3D printing forming manufacturing forming; magnetizing the surface of the unit basic geometry model;carrying out grid-type modular free combination on the magnetization unit body models to generate a new combination body model; and observing the forming process of related intersection lines and intersecting lines of the inner surface and the outer surface of the new assembly model, and analyzing the view projection characteristics. The manufacturing method has the advantages that: due to the modular design characteristic, flexible disassembly and assembly, free combination and convenience in carrying can be realized by utilizing a magnetic principle; due to the detachable characteristic, theinner structure and the outer structure can be observed in all directions, and the forming process of the intersection lines and the intersecting lines of the three-dimensional surface can also be observed and analyzed through model combination; and each basic unit body is of a thin-wall hollow structure and is manufactured through the 3D printing technology, and the requirement for light weightis met.

Description

technical field [0001] The purpose of the present invention is to provide a method for making a model, specifically a method for making a grid-combined graphical model based on the principle of magnetism. Background technique [0002] The traditional drawing teaching aids commonly used in the market have always been wooden and plastic products, which are made by cutting and injection molding. The models correspond to the design of classic examples in textbooks. The shape is an integral structure or a half-cut structure. The shape changes, and it is bulky and inconvenient to carry. Among them, the common connection and combination methods of geometric bodies are thread connection, key connection, pin connection or glue bonding, etc., which cannot be disassembled; this design is a DIY combinable graphics physical model teaching tool that is different from the concept of traditional drawing teaching aids and learning models. . Contents of the invention [0003] The purpose ...
