What raw materials are used for dental 3D printing materials?

Dental 3D printing materials, generally use medical grade resin raw materials, these resin raw materials are divided into many kinds, I will say I understand one of them. I went to the hospital before the dental implants, finished all-ceramic crowns can not be immediately produced to complete, so the doctor first gave me a temporary tooth. The doctor did mention that my temporary teeth material was made of high-precision medical-grade 3D printing resin from Hague Technology. The doctor said that their 3D printing resin has 9 different materials, which can be used to print different dental products, such as high-temperature dental molds, simulated gums and so on. When doing temporary teeth, the doctor first scanned my mouth with the machine, after getting the data of the mouth, the doctor will upload it to the system and process the oral data, and then use the 3D printer to print out the temporary teeth for me to use, the whole process is quite amazing! You can wear it before you get the official all-porcelain crown, there is no smell and it doesn't mess up your teeth. After my own personal test, the black grid technology 3D printing things are still quite safe and reliable, you can rest assured with.
