Open the mouth, aim at the teeth 3D scan, 3D printer can print a zirconia ceramic denture... Reporter learned from Kunshan Industrial Technology Research Institute on the 21st, the hospital's incubator team Bolimai company independently developed the domestic first industry A high-performance ceramic 3D printer and matching ceramic paste were introduced, and obtained the first medical device registration certificate for 3D printed ceramic dentures in China.
Before the advent of 3D printing technology, people made a denture, needed to bite the tooth membrane, and then sent to the factory for production, and repeated carving, the production cycle is longer, and 3D printing technology not only improves efficiency, but also greatly saves materials. In recent years, metal 3D printing technology has been gradually applied to the manufacture of crowns, bridges, brackets, etc., but 3D printing of ceramic dentures is difficult. The difficulty lies in the material and laser curing technology, which can be quickly condensed while maintaining the fluidity of the material.
According to reports, the ceramic 3D printer uses laser scanning to cure high ceramic content paste. The laser power, laser spot size, and scanning speed are variable during printing.
At present, the products of 3D printed zirconia ceramic denture production line have passed the mechanical properties and biological inspection, and in October 2017, they obtained the first medical device registration certificate for 3D printed ceramic dentures in China. It is reported that the material utilization rate of the 3D printed zirconia ceramic denture can reach more than 90%, the denture has no internal crack and the cost is low, which is very beneficial to the popularization and application of 3D printed ceramic denture.
After testing, this ceramic 3D printer and supporting materials have completely independent intellectual property rights, and its performance has reached the advanced level in foreign countries. The price is only 1/4 of that of imported equipment, and all 3D printing materials are independently developed and produced, which can completely replace imported. (Technology Daily)
