The invention provides a method and
system for producing false teeth by using 3D printing, and relates to the field of digital design and manufacturing, and the method comprises the following steps: obtaining a 3D false tooth model of the
oral cavity of a patient, generating an optimal printing path through a 3D false tooth model path optimization
algorithm, automatically generating a support structure according to the 3D false tooth model, the printing path and the structural characteristics of the 3D false tooth model, and carrying out 3D printing on the 3D false tooth model. A
simulation model is established, temperature distribution, mechanical properties, a supporting effect and a printing path in the 3D printing process are simulated and analyzed, according to a
simulation result, possible problems are predicted, the printing technology is optimized and adjusted to obtain optimized path planning data and adjusted printing parameters, and a
machining scheme is formed. Therefore, precision improvement and performance optimization of false tooth production and
automatic control of the production process are realized. In combination with closed-
loop control of an intelligent feedback mechanism, not only is the product quality improved, but also the production efficiency is enhanced, the cost is reduced, and a new solution is provided for technical upgrading and industrial application in the false tooth production field.
