Abstract
An additive-manufacturing resin vat system can include a resin vat, a flexible plastic film, a transparent support window, a transparent conductive coating, a support tray, and a set of metal contacts. The resin vat can carry a resin-print material mixture. The flexible plastic film can mechanically seal to a bottom of the resin vat. The transparent support window can support the flexible plastic film. The transparent conductive coating can be formed on at least one side of the transparent support window. The support tray can define an outer tray portion and an open tray interior, the outer tray portion carrying the transparent support window. The metal contacts can be carried by the outer tray portion and configured to electrically couple with the transparent conductive coating. The transparent conductive coating is configured to generate heat upon receiving an electrical current via the metal contacts.
