Recently, the importance of the construction technology of the free-formed buildings is becoming more significant, as the interest and demand for the free-formed buildings are increasing. However, it takes much time and cost during the construction of free-formed buildings because the current construction technique of freeform concrete segments is manufactured by a formwork. Therefore, in this study, we suggested a new manufacturing process based on the LOM-type 3D printer for freeform concrete segments that can shorten construction time and reduce cost when constructing freeform concrete segments, and we also verified the feasibility of production process through mock-up test. The result shows that the suggested process shortened 47.8% of production time and saved 56.2% of cost compared to the existing steel formwork method. In conclusion, it is expected that the production method of freeform concrete segments using 3D printer will contribute to the improvement of productivity of freeform concrete segments construction and the activation of new construction method for free-formed building construction. |
