Abstract: Various embodiments of the present disclosure disclose manifolds, methods, and systems for measuring cell functions. In various embodiments, a first reservoir storing a first fluid and a second reservoir storing a second fluid may be fluidically connected via a fluid channel. Further, the first fluid and the second fluid may be such that an entropic gradient force causes the first fluid to flow towards a container that is located therebetween and contains cells therein. The cells release cell products into the first fluid flowing in the fluidic channel, which in turn flows into the second reservoir. The cell products can be sampled from the second reservoir and/or from the container to measure the function of the cells.

Abstract: There is provided improved laser sintering systems that increase the powder density and reduce anomalies of the powder layers that are sintered, that measure the laser power within the build chamber for automatic calibration during a build process, that deposit powder into the build chamber through a chute to minimize dusting, and that scrubs the air and cools the radiant heaters with recirculated scrubbed air. The improvements enable the laser sintering systems to make parts that are of higher and more consistent quality, precision, and strength, while enabling the user of the laser sintering systems to reuse greater proportions of previously used but unsintered powder.

The 3D printing system includes a resin vessel, a tank agitation subsystem, a fabrication subsystem, and a controller. The resin vessel is configured to contain photocurable resin and has a lower region within a distance H of a bottom surface of the resin vessel. The agitation subsystem includes (a) a grating disposed within the lower region of the resin vessel and (b) an agitation movement mechanism coupled to the grating. The fabrication subsystem is configured to form the 3D article by a layer-by-layer selective curing of the photocurable resin. The controller is configured to operate the agitation movement mechanism to oscillate the grating along a lateral Y-axis to remix filler particulates within the photocurable resin.
