Abstract: In a computational modeling method for identifying how to apply a modifying agent during a three-dimensional (3D) printing method, a thermal diffusion model of a layer of a 3D object to be formed from a portion of a sinterable material using the 3D printing method is created. The thermal diffusion model is created by a computer running computer readable instructions stored on a non-transitory, tangible computer readable storage medium. A quantity of the modifying agent to be selectively applied is calculated, by the computer, based upon the thermal diffusion model.

Abstract: A drying apparatus usable with a printing system includes a housing, a first set of radiative heating elements, a second set of radiative heating elements, and an air handling device. The housing includes a front region and a rear region adjacent to the front region. The front region includes an inlet to receive media. The rear region includes an outlet to pass media there through. The first set of radiative heating elements is disposed within the front region to heat the media. The second set of radiative heating elements is disposed within the rear region to heat the media. The air handling device is disposed across from the second set of radiative heating elements to jet air within the rear region to cool the media prior to the media being passed through the outlet.
