技術說明

本發明的積層製造3D列印技術主要利用負溫感水膠為模板簡化了製造流程，並具有雙連續相互穿的孔道，良好的收縮率控制以及高緻密化，使得陶瓷支架具有更出色的機械性能。這些優點使本發明可成為專利技術的原因。與其他3D列印材料系統相比，陶瓷材料仍處於研發初期的材料。儘管有幾種類似的技術，但本技術具有高特異性和高燒結緻密性的特點，因此，在傳統陶瓷，玻璃，精密陶瓷和金屬的市場價值中具有很大的潛力。特別是用於醫療產品（如植入的生物陶瓷植入物）或牙冠材料（如牙科用氧化鋯和氧化鋁）時，提供了更好的策略方法。 The 3D ceramic printing patent of the present invention mainly　simplifies the manufacturing process by utilizing a negative thermo-responsive hydrogel template and obtains an improved bi-continuous phase interpenetrating pore channel, a well-controlled shrinkage rate, in addition, high densification which allows ceramic scaffolds to have excellent mechanical properties. These advantages set the direction for the present　invention to be a patentable technology. As compared to other 3D printing　material systems, the ceramic material is the only material that is still in the initial　stage of research and development. Although there are several similar types of　technologies, this technology has the characteristics of high specificity and high　sintering densification, as a result, it has high potential in the market value of traditional ceramics, glass, precision ceramics and metals. In addition, it is a better goal when being used especially as medical supplies such as implanted　bioceramic implants or tooth crown material such as dental use zirconia and alumina.
