The IAMA system with Automatic Virtual Metrology (AVM) technology can enable a 3D printing laser powder bed fusion (LPBF) machine to achieve the world＇s first innovative capability of online layer-to-layer quality predictionfeedback control, which improves the final product quality such as tensile strengthsurface roughnessrealize the goal of nearly Zero Defects of all products.

To train neurosurgery internsincrease their confidencesurgical skills, we employed 3D printing, mold design,casting technology to develop medical simulators. The simulators allow students to adjust the angle of the head based on the location of the angioma (brain tumor), perform a craniotomy, move the soft tissue of the brain aside using forceps, locate the angioma (brain tumor),clip the angioma (remove the brain tumor) using medical instruments,complete the entire training while artificial blood is flowing through the simulator.

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.
