Embodiment 1

[0043] The specific process of using 3D printing to produce multi-material buildings that contain multiple independent distributions is as follows:

[0044] Establish its 3D CAD solid model based on the pre-printed multi-material building, which includes four molding materials, namely concrete 1, wood-plastic 2, plastic 3 and plaster 9; for the building model 3 is a cantilevered structure, The corresponding supporting structures 9 and 10 are designed and generated in the computer, 9 of which will be retained after printing is completed, and 10 will be dismantled after printing; the materials used in this multi-material building have their obvious material interfaces with each other, and have their own The respective material properties; the computer slices the 3D CAD solid model including the support structure, and obtains the structural information, material information and motion trajectory of the solid part and support part of each layer; during the printing process of each ...

Embodiment 2

[0046] The present invention can also print buildings containing organic mixtures of various materials, the following examples combine image 3 and Figure 4 Be explained.

[0047] Establish its three-dimensional CAD solid model according to the pre-printed multi-material building, the solid model includes three kinds of molding materials, respectively wood 20, plastic 30 and plaster 12, wood 20 and plastic 30 are the solid parts of the building, and gypsum 12 is The supporting part of the building also plays a decorative role, and will not be dismantled after printing is completed; the solid part of the building is organically composed of two materials: wood 20 and plastic 30, the bottom is nearly 100% wood, and the top is nearly 100% plastic , the middle part is the wood-plastic material mixed in different proportions; when printing a certain layer 110 of the building, this layer includes two parts 111 and 112, of which 111 is wood 20 and plastic 30 in a certain proportion ...

Abstract

The invention discloses a three-dimensional printing and molding method for manufacturing a multi-material building or a large-size object layer by layer by adopting a plurality of nozzles, a plurality of types of materials and a three-dimensional printing technology. The three-dimensional printing and molding method comprises the following steps: establishing a three-dimensional CAD (Computer Aided Design) solid model of the multi-material building according to a pre-three-dimensional printed multi-material building; slicing and layering the three-dimensional CAD solid model to obtain machining information including solid structure information, material distribution information, movement tracks and the like of each layer; in a printing process of the multi-material building, conveying a plurality of types of molding materials by adopting a plurality of printing heads respectively, stacking layer by layer and carrying out printing and molding; carrying out treatment including polishing, spraying, wire arrangement, supporting removal and the like of the printed building model so as to obtain the building containing a plurality of types of materials. With the adoption of the three-dimensional printing and molding method, the integration of designing and manufacturing of a three-dimensional structure and a material of the multi-material building is realized; the comprehensive performance of the building is greatly improved; the three-dimensional printing and molding method is particularly applicable to the printing and molding of a functional building, and has a wide application prospect in the field of molding of buildings or models of landscape sculptures, artificial hills, home furniture and the like.

Description

technical field [0001] The invention relates to a three-dimensional printing molding method for a multi-material building, and belongs to the technical field of 3D printing. Background technique [0002] Architectural 3D printing (also known as 3D printing architecture, architectural 3D printing, 3D printing architecture, etc.) is a 3D printing molding method that uses 3D printing technology to produce large objects (including urban sculptures, landscape architecture, functional buildings, etc.). It integrates computer, automation, machinery, electronics, materials and other disciplines into one. The basic principle of architectural 3D printing technology is: according to the pre-printed physical building, design its 3D CAD solid digital model through digital modeling software or technology, use computer to control giant 3D printing equipment and related systems to extrude architectural molding materials, layer by layer Print and stack molding to turn design blueprints in...
