Problems solved by technology

The inflatable model has the characteristics of high compression ratio, folding and portable transportation; however, it is relatively lacking in the appearance simulation of detailed features, so it is similar to the entity in terms of similarity; at the same time, due to the air leakage of the film, it needs to be used constantly. pump air
Foam plastic models and plaster models have the characteristics of high simulation, and are very similar to the entity in terms of detailed description, so they are also commonly used models; however, they need to be specially protected during transportation to avoid damage to the detailed features of the model caused by bumps. Therefore, lack of portability
In addition, these three types of models have relatively good weather resistance and cannot be rapidly degraded by factors such as microorganisms, light, heat, acid, and alkali in the environment. Therefore, they can exist in nature in the form of garbage for a long time, and are relatively environmentally friendly. Difference

Abstract

Belonging to the technical field of polymer materials, the invention relates to a preparation method of a high compression ratio 3D high simulation self-expansion model and a product. The method mainly includes the steps of: (1) taking high compressible resin, degradable resin, fiber, a compatilizer, an antioxidant and a lubricant as the raw materials to prepare a high compressible and degradablereinforced composite material; and (2) using the high compressible and degradable reinforced composite material prepared by step (1) as the raw material, conducting fused deposition 3D printing molding, and then performing milling to obtain the high compression ratio 3D high simulation self-expansion model. The self-expansion model prepared by the method has the characteristics of high simulation,high compressibility, environmental friendliness and the like. At the same time, the self-expansion model can realize fast compression, expansion and other functions, and can be widely applied to industrial design, aerospace, commercial self-exhibition, real estate sales, academic exchange and other fields.
