Directly writing 3D structures into supporting mediums is a relatively new developing technology. The liquid-like solid (LLS) materials are developed as supporting mediums, that possesses the self-healing ability and tunable yield stress. Because the components of this emulsion glass are mostly water and oil, it exhibits chemical stability when exposed to UV radiation and high temperature. Based on the above features, this emulsion glass can be regarded as a new kind of LLS material for supporting mediums.

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,developing printable concrete that can actually be used for printing. The second is the simulation, analysisoptimization technology of the concrete 3D printing process. The infinite element method developed by ourselves is used to simulateanalyze the concrete 3D printing process,the geometric of the object is considered to optimize the printing pathparameters.
