| Abstract: |
3D printing technology has the sustainable advantages of saving formwork, labor and time, reducing pollution and so on, so it is gradually applied to the field of bridge engineering. In order to explore the advantages and potential of 3D printing technology in carbon reduction, this paper makes a comparative analysis on the carbon emission of 3D printing and cast-in-situ construction in the materialization stage of complex shaped pier. The results show that the carbon emission in the materialization stage mainly comes from the production stage of building materials, and the proportion of carbon emission in the construction stage and transportation stage is very small; The combination of 3D printing shell and cast-in-situ construction has less carbon emission than using one of the construction methods alone; Compared with traditional construction, the application of 3D printing technology reduces the carbon emission of this example by more than 20%. |
