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.

The technology realizes a perovskite nanocrystal-polymer composite material, which has extremely high stability at room temperaturehigh temperature. It can be used for 3D printing, shaped into fluorescent microfilaments,can also be used for white light-emitting diodes. The application of this air-stabile perovskite nanocrystal-polymer composite material in the 3D printing industry, texti

Through the study of structural biological materialthe multiscale analysissimulation, we construct an initiative integrated platform, which provides user-friendly experience, automatically generates designs of lightweight structure for the demandsoffers various choices of materialssuggestions. This design platform contains great potential for engineering applications.

Here we present a portable microfluidic device that can perform immunoassay for infectious disease diagnosis or detect heavy metal ions in water samples. The device is composed of two major components: nanomaterials modified paper-based detection platform and semi-automated flow manipulator. A reusable 3D-printed device is used to hold a disposable detection pad that modified with functional nanomaterials for water quality monitoring or antibodies for disease diagnosis. Besides, the use of spring-containing 3D-printed syringes manipulates a large-volume sample without manual actuation. Meanwhile, by controlling the flow rate via the linked flow regulator at the syringe outlet, solutions can react stably with the paper platform, which provides detection and pre-concentration effects.

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.
