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: An apparatus for bottom-up fabrication of three dimensional objects, the apparatus comprising: a vat for a photosensitive polymer, the floor of the vat including a working surface arranged such that, in use, light incident on the working surface interacts with the photosensitive polymer at the working surface to fabricate a portion of the three dimensional object; a build platform capable of being inserted into the vat, the build platform having a planar surface; an elevator mechanism capable of adjusting the separation between the working surface of the vat and the planar surface of the build platform; and a rotation mechanism capable of varying the relative rotational position of the vat relative to the build platform, the relative rotation being about an axis which is normal to the working surface of the vat.

Abstract: The present disclosure provides a thermal management device comprising a vapor chamber, a heat pipe in fluid communication with the vapor chamber, and a fin in thermal contact with the heat pipe. The vapor chamber may contain a first working fluid and may facilitate transfer of thermal energy from a source of thermal energy to the first working fluid. The fin may comprise a fluid flow path configured to direct a second working fluid from a first opening to a second opening. The first opening may be oriented along a first direction of flow towards the fin, and the second opening may be oriented along a second direction different than the first direction. The heat pipe may direct the first working fluid from the vapor chamber through the heat pipe and may facilitate transfer of thermal energy from the first working fluid to the fin or the second working fluid.

Abstract: The present disclosure provides a system for printing a three-dimensional object. The system may comprise an open platform configured to hold a film of a viscous liquid comprising a photoactive resin. The open platform may comprise a print window. The system may comprise a deposition head comprising a nozzle in fluid communication with a source of the viscous liquid.
