Rendering system energy recovery

Abstract

A rendering apparatus, in an example, comprises a rendering zone disposed between a rendering material deposition head and a substrate, a processing module to process the rendering material, a heat exchanger to transfer heat from the processing module to air to be re-distributed to the rendering zone, a distribution system for re-distributing heated air to the rendering zone, a valve located between the heat exchanger and the rendering zone, a temperature sensor located in the rendering zone to detect a temperature of the heated air that is re-distributed to the rendering zone, and a control module to adjust a temperature of the rendering zone by controlling an aperture of the valve using a feedback signal received from the temperature sensor.
