3D printing building structure material and use method thereof

Abstract

The invention discloses a 3D printing building structure material and a use method thereof and relates to the technical field of 3D printing. The 3D printing building structure material comprises the following components in parts by weight: 40-70 parts of construction waste, 10-15 parts of household garbage, 8-20 parts of fibers, 5-20 parts of lightweight aggregates and 20-40 parts of water. In a use process, the construction waste and the household garbage at a formula ratio are smashed, the fibers, the lightweight aggregates, rubber powder, gypsum, powder padding and water are added and stirred till reaching a sticky slurry state, and then the sticky slurry is put into a 3D printing system for performing 3D printing according to a required building structure. According to the invention, the technical problems of poor caking property and crack resistance and large raw material consumption of the building material for 3D printing are solved. The invention provides a green 3D printing material which utilizes the structure materials, such as, cement, gravels and rebar in the construction waste and the substances, such as, fibers, in the household garbage, is high in material toughness and is high in caking property and crack resistance.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing building structure material and a method for using the same. Background technique [0002] Since the advent of 3D printing technology, it has rapidly changed the production processes of many industries and achieved production effects that are difficult to achieve with traditional processes. In the traditional manufacturing field, the product cost is largely derived from the standard mold and shared through standardized and large-scale production. 3D printing technology can make the cost of a single product independent of its production quantity, and can carry out personalized and customized production of products, so as to reach the advanced manufacturing level. At present, the advantages of 3D printing technology are concentrated in the field of industrial design. 3D printers use powdered plastic or metal as raw materials, and adopt digital modeling and layer-...

AI Technical Summary

Problems solved by technology

[0006] 1. At present, 3D printing buildings are mainly aimed at decorative building materials such as walls. The effect of using 3D printing structural buildings is not good, mainly because the adhesion and crack resistance of printing materials are poor, resulting in the printed structural low building strength;

[0007] 2. It needs to consume a lot of cement, sand and gravel and other aggregates, which does not meet the development concept of material reduction and recycling
