Dynamic thermoforming of dental appliances

A non-transitory computer-readable storage medium storing instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• identifying, based on image data from an imaging device, first geometry of a first mold associated with a first dental arch and a second geometry of a second mold associated with a second dental arch;
• determining, based on the first geometry and the second geometry, that the first mold and the second mold are to be used for simultaneous forming of a first dental appliance and a second dental appliance on a plate in a dental appliance manufacturing system;
• and
• causing, based on the first geometry and the second geometry, one or more portions of the dental appliance manufacturing system to be configured to form the first dental appliance and the second dental appliance, wherein the causing of the one or more portions of the dental appliance manufacturing system to be configured comprises adjusting corresponding size of the one or more portions of the dental appliance manufacturing system.
