  • SYSTEMS AND METHODS FOR TREATING A PRINTED MODEL
    Publication number: 20220324165
    Abstract: The present disclosure relates to systems and methods for treating a printed model. The methods may include placing at least a portion of the printed model into a heat treatment medium. The methods may further include performing a heat treatment on the printed model based at least in part on the heat treatment medium. The heat treatment medium may provide a constraint force to prevent a deformation of the printed model during the heat treatment. And the methods may also include obtaining a printed object based at least in part on the heat treatment performed on the printed model.
