Material test and connection structure research of landscape bridge structural decoration based on 3D printing technology

In view of the problems and needs of structural ornaments in the artistic creation of bridge appearance, combined with the technical advantages of 3D printing technology, and from the perspective of ensuring structural safety and durability, the 3D printing materials and implementation of structural bridge ornaments are studied. The optimization of the 3D printing path and process parameters, the advantages and disadvantages of 3D printing materials are studied in detail. On this basis, the experimental research on 3D printing materials of structural bridge ornaments is focused. Through the tensile and bending strength tests, high and low-temperature cycle tests, and high-temperature deformation tests, the feasibility of applying ABS materials to the 3D printing of structural bridge ornaments is determined. The connection mode between 3D printing ornaments and the bridge's main structure and the connection mode between brackets and 3D printing ornaments are studied and proposed in detail, which provides a practical technical means and methods for the realization of 3D printing of bridge structural ornaments.
