Abstract: The present disclosure provides advantageous porous assemblies, and improved systems and methods for utilizing and/or fabricating the porous assemblies. More particularly, the present disclosure provides porous assemblies fabricated at least in part by additive manufacturing (e.g., via a 3D printing process, such as, for example, via an electron beam additive manufacturing process, via a laser additive manufacturing technology, via an inkjet or a binder jet additive manufacturing process, etc.), the porous assemblies including a porous monolith support structure or substrate for a sensitive or active layer of a multi-layer application (e.g., for sensitive/active layers in fuel cell/electrolyzer/battery and other multi-layer applications).

Abstract: The present disclosure provides advantageous selectable media filter and sparger assemblies, and improved systems/methods for utilizing and/or fabricating the selectable media filter and sparger assemblies. More particularly, the present disclosure provides selectable media filter and sparger assemblies fabricated at least in part by additive manufacturing (e.g., via a 3D printing process, such as, for example, via a laser powder bed fusion (LPBF) process, via an electron-beam melting (“EBM”) process, via an inkjet or a binder-jet additive manufacturing process, etc.), the selectable media filter and sparger assemblies including a plurality of filtration and/or sparging members attached to a single housing, with each filtration/sparging member having an independent connection port.

Abstract: The present disclosure provides advantageous rotary interfaces for fluid assemblies (e.g., rotary interfaces for fluid flow in bioreactor applications), and related methods of fabrication and use. More particularly, the present disclosure provides improved rotary interfaces for fluid flow through porous impellers for filtration and/or sparging for fluid assemblies (e.g., bioreactor applications), and related methods of fabrication and use. Disclosed herein is a fluid assembly (e.g., bioreactor) that includes a porous impeller which is in fluid communication with a hollow shaft that can be used to transport a reaction fluid to an external storage tank or the like. The fluid assembly/bioreactor can include a coupling mechanism that transmits rotary motion from a motor to a primary shaft and then to a hollow secondary shaft, while at the same time permitting removal of a filtrate from the fluid assembly or bioreactor via the hollow secondary shaft and a porous impeller.

Abstract: Disclosed herein are advantageous phase separator devices, and related methods of fabrication and use thereof. The present disclosure provides improved phase separator devices for phase separation of feedstreams, and improved systems/methods for utilizing and fabricating the phase separator devices. More particularly, the present disclosure provides porous (e.g., three-dimensional gradient porous) phase separator devices for phase separation of fluid mixtures (e.g., to separate a two-phase fluid mixture) to a first fluid phase flow (e.g., to a liquid flow) and to a second fluid phase flow (e.g., to a gas flow). At least a portion of the phase separator devices of the present disclosure can be fabricated via machining, powder metallurgy (e.g., sintering), and/or produced utilizing additive manufacturing techniques.
