Abstract: The present disclosure provides a thermal management device. In some cases, the thermal management device may comprise a first portion of a housing. The first portion may be configured to facilitate a transfer of a first thermal energy from a first surface of an integrated circuit module (ICM) to a surface of the first portion, or vice versa. The thermal management device may further comprise a first plurality of channels disposed within the first portion. The first plurality of channels may be configured to provide a first fluid flow path in thermal contact with the first portion. The first fluid flow path may be configured to facilitate a transfer of the first thermal energy from the first portion to a cooling fluid disposed within the first fluid flow path.

Abstract: Methods, systems, and apparatus, including a method of multi-material stereolithographic three dimensional printing comprising, depositing a first material through a first material dispenser of a stereolithographic three dimensional printer onto an optical exposure window to form a first material layer; curing the first material layer to form a first material structure on a build head of the stereolithographic three dimensional printer; depositing a second material through the first material dispenser or a second material dispenser onto the optical exposure window to form a second material layer; and curing the second material layer to form a second material structure on the build head.

Abstract: The present disclosure provides methods and systems for printing a three-dimensional (3D) object. The methods may comprise providing, adjacent to a build surface, a film comprising a polymeric precursor. A sensor may be used to determine a profile of the film. The profile may be indicative of a quality of the film. If the profile meets a quality threshold, at least a portion of the film may be exposed to light to initiate formation of a polymeric material from the polymeric precursor, thereby printing at least a portion of the 3D object.
