Research on Block Segmentation and Assembly Technology of 3D Printing Structure

There have been reports of attempts and experiments on 3D printing technology in the construction industry. However, due to the huge volume and complex diversity of the building structure, the desire for 3D printing of architectural structure faces difficulties and technical problems in terms of printing size and materials. This paper introduces the digital modeling principle, block segmentation principle, applicable principle of printer and corresponding assembly method of 3D printing of architectural structure. Practical results have been obtained through experiments of different types of 3D printer, which can break complex components into parts. At low cost, only modeling and printing is needed to form components, and the whole building structure can be completed by combining different ways of connection. With the expansion of 3D printing technology and materials, it can be predicted that the use of 3D printing for block segmentation and assembly molding will become another branch of prefabricated buildings.
