Main differences of printing fluid: product strength, hardness, high temperature resistance, shrinkage ratio and toxicity.
Compared with the printing fluid for printing toys, the biggest problem is poor performance, which cannot meet the requirements of dental applications. For example, the printing accuracy of model materials is poor. The teeth made according to this will definitely have certain errors, and at the same time, the long-term stability is poor. Models It is easy to deform after being stored for a few days, and the strength is poor. For example, it is easy to break the model when it is dropped, or when the retainer or invisible aligner is pressed, or it is directly deformed; for example, the material of the guide plate is very brittle. easy to break.
