Ceramic Photocuring Technology For Producing All-ceramic Teeth

Mar 28, 2019

Anyone who has done all-ceramic teeth knows that to make a high-quality all-ceramic tooth has a strict surgical procedure. First of all, there is a need for a dental impression, and then a plaster model, a series of complicated processes, and the price is very expensive, and it is currently not the first choice for the mainstream of the tooth and the mass dental restoration. However, through ceramic light curing technology, it is possible to use the data to print all the porcelain teeth easily, which not only saves these complicated procedures, but also saves the patient a lot of cost.


The ceramic photocuring technology is to add the ceramic powder into the photocurable solution, and the ceramic powder is uniformly dispersed in the solution by high-speed stirring to prepare a ceramic slurry having a high solid content and a low viscosity, and then the ceramic slurry is photocured. The machine is directly layer-by-layer cured, and the ceramic parts are obtained by adding the ceramic parts. Finally, the ceramic parts are obtained by a drying, degreasing and sintering process.

Some time ago, a ceramic 3D printer developed by a 3D printing company took more than two hours to print the first coin-sized ceramic gear workpiece with 40% ceramic solid content. Soon after, the company successfully broke through a number of technologies such as ceramic sintering, and continuously improved the solid content of ceramics, which was widely praised by the industry, and thus launched the cooperation of production, education and research of ceramic 3D printing consumables.


In addition to dental care, the market for ceramic printing is very promising. At present, the turbine blades in aero-engines are made of metal, but the metal can not withstand high temperatures, so it also affects the speed of the engine. If it can be replaced with high-precision ceramic turbine blades, the high temperature resistance of the ceramics will greatly increase the speed of the entire engine. . In the future, ceramic 3D printers will be applied to aerospace, military, machinery and other fields.
