Latest Patents

Among his latest patents, Keng-Liang Ou has developed a method for producing alpha-calcium sulfate hemihydrate bone graft. This invention presents a novel technique involving the mixing of calcium sulfate dihydrate and deionized water to create a paste. The process includes stirring and heating the mixture at a temperature of at least 160°C within a pressure range of 100-350 psi, resulting in conversion to calcium sulfate hemihydrate. The filtered product is then washed with absolute alcohol, yielding a high-purity bone graft suitable for biomedical applications. This method stands out for its absence of catalysts, impressive mechanical strength, biocompatibility, and a secure curing process maintained at a maximum temperature of only 31°C.

Another noteworthy patent is a system for online monitoring powder-based 3D printing processes. The system utilizes a uniform monochromatic light source to analyze the powder layer before and after glue application. By comparing reflected images and detecting any defects larger than a predefined threshold, the system can automatically terminate the printing process when necessary. This innovation optimizes efficiency and resource use during 3D printing, ensuring high-quality production standards.
