This technology contains two important sub-technologies. The first is the development of ultra-high performance concrete composite materials, mastering the 3D printing related properties, and developing printable concrete that can actually be used for printing. The second is the simulation, analysis and optimization technology of the concrete 3D printing process. The infinite element method developed by ourselves is used to simulate and analyze the concrete 3D printing process, and the geometric of the object is considered to optimize the printing path and parameters.
The substainable ultra-high performance concrete of this technology is the first printable concrete material developed in Taiwan, which will solve the characteristics of traditional concrete materials that are easy to crack, low strength and not easy to stack. In addition, the concrete 3D printing processes analysis and optimization technology is the first developed in Taiwan, which can use less computing time to analyze the mechanical behavior of the 3D printing process and optimize the parameters and paths.
This technology can not only be applied to the concrete industry, such as construction, transportation, and infrastructure, but also can be extended to general livelihood products, so that Taiwan’s technologies of the concrete 3D printing can rank among the world＇s leading groups.
