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.

3D printing system with waste collection subsystem
A three-dimensional (3D) printing system includes a resin vessel, a fabrication subsystem, a waste collection subsystem, and a controller. The resin vessel is configured to contain photocurable resin. The fabrication subsystem is configured to form the 3D article with layer-by-layer selective curing of the photocurable resin. The fabrication subsystem includes a build plate, a build plate support structure, and a vertical movement mechanism. The waste collection subsystem is attached to the build plate support structure and configured to capture partially polymerized resin as the build plate support structure moves in an upward direction. The controller is configured to (a) operate the vertical movement mechanism to translate the build plate support structure to a lower position and (b) operate the vertical movement mechanism to raise the waste collection subsystem up through the resin and to a position at which partially polymerized resin can be unloaded from the waste collection subsystem.
A manufacturing system includes an additive manufacturing (AM) system and a fluid supported molding system. The AM system is configured to produce a plastic mold. The fluid supported molding system includes a pressure vessel surrounding a pressure chamber. The pressure vessel is configured to contain a fluid surrounding the mold. The fluid supported molding system also includes a mold material injector configured to inject a mold material into the mold. During the injection of mold material into the mold, the fluid surrounding the mold is configured to resist defection of an outer surface of the mold.
Disclosed is a bioextruder assembly capable of “retro-fit” an existing three-dimensional (3D) printer such that it is capable of printing biomaterials. The bioextruder assembly may be modular, self-contained, and configured as “plug-and-play” unit. In some embodiments, the bioextruder assembly may be configured for use in zero-gravity environments such as space and configured to engage with existing 3D printers in space. In some embodiments the bioextruder assembly includes an extruder configured to extrude bio-materials stored in a syringe that is coupled to the extruder, and a converter. The converter may include an electromechanical coupling component that couples the converter to a three-dimensional printer system, and a motor configured to actuate the extrusion of bio-materials stored in the syringe based on signals received from the three-dimensional printing system via the electromechanical coupling component. In some embodiments, the converter may be configured to reversibly attach to the extruder via an attachment element.
