Publication number: 20250122638Abstract: An apparatus for use in electrochemical layer deposition includes an anode array containing a plurality of independently electrically controllable anodes and immersible in an electrolyte. The plurality of anodes are arranged in a two-dimensional array. The anode array is connected electrically to, or disposed upon an integrated circuit, semiconductor, or combination of conductive and insulative elements meant for biasing the plurality of anodes with a potential. An anode addressing circuit is provided to receive a signal containing anode address data and to output a signal causing an anode array pattern. The anode addressing circuit communicates with a controller and the anode array. The controller is configured to electrically control each one of the plurality of anodes in the anode array to result in an electrochemical reaction at a cathode to deposit a layer corresponding to the anode array pattern signal received from the addressing circuit.Type: ApplicationFiled: December 19, 2024Publication date: April 17, 2025Applicant: Fabric8Labs, Inc.Inventors: David Forrest Pain, David Morgan Wirth, Jeffrey William Herman

Patent number: 12264405Abstract: Described herein are electrochemical additive manufacturing systems and methods of using such systems. In some examples, a method comprises flowing an electrolyte solution into the gap formed by an electrode array and a deposition electrode and depositing (electroplating) a target material onto the deposition electrode. The method also comprises changing one or more characteristics of the electrolyte solution within the system, e.g., to remove deposition byproducts, replenish consumed components, and/or change the solution composition to modify various properties of the deposited target material (e.g., composition, morphology) without major changeovers within the system. These electrolyte changes can be performed dynamically while the system continues to operate. The changed characteristics can be acid concentration, feedstock ion concentration, additive concentration, temperature, and flow rate.Type: GrantFiled: August 30, 2022Date of Patent: April 1, 2025Assignee: Fabric8Labs, Inc.Inventors: David Pain, Jeffrey Herman, Kareemullah Shaik, Andrew Edmonds

Patent number: 12257784Abstract: Described herein are electrochemical-additive manufacturing methods and systems using such methods. A method comprises depositing a material onto a deposition electrode by flowing a current between that deposition electrode and each of multiple individually-addressable electrodes, forming an electrode array. These currents are independently controlled based on a target map and using deposition control circuits, each coupled to one individually-addressable electrode. The target map is generated by a system controller based on various characteristics of the system (e.g., the performance of each deposition control circuit and/or individually-addressable electrode, electrolyte composition) and the desired characteristics of the deposited material (e.g., deposition location, uniformity, morphology). Furthermore, when the deposition electrode and the electrode array move relative to each other, the system controller dynamically updates the target map based on their relative positions.Type: GrantFiled: February 29, 2024Date of Patent: March 25, 2025Assignee: Fabric8Labs, Inc.Inventors: David Pain, Kareemullah Shaik, Joshua Gillespie, Jeffrey Herman

Publication number: 20250003101Abstract: Described herein are printheads for electrochemical-additive manufacturing (ECAM) comprising extended electrode interconnects and other features for preventing electrolyte ingress and protecting the electrode-interface circuits of these printheads. For example, an electrode interconnect may comprise a metal trace extending in-plane between and interconnecting two vertical (out-of-plane) conductors such that the shortest/direct distance between these vertical conductors is substantially smaller than the length/path of this metal trace. As such, the metal trace substantially increases the electrolyte migration path between these vertical conductors. Furthermore, multiple metal traces (at different levels) may be used with vertical conductors being offset from each other. Finally, electrode edges may protrude into the insulator recesses thereby preventing these edges from peeling and increasing the contact interface between the electrodes and the insulator.Type: ApplicationFiled: February 20, 2024Publication date: January 2, 2025Applicant: Fabric8Labs, Inc.Inventors: Ryan Nicholl, David Pain, Edward White, Lewis Fowler-Gerace

ELECTROCHEMICAL-ADDITIVE MANUFACTURING SYSTEMS COMPRISING MEMBRANES AND METHODS OF OPERATING THEREOF
Publication number: 20240229273Abstract: Described herein are electrochemical-additive manufacturing (ECAM) systems comprising membranes and methods of operating thereof. An ECAM system comprises an electrode array with individually-addressable electrodes, a deposition electrode, and a membrane positioned between the deposition electrode and electrode array. In some examples, the membrane is configured to transmit protons while blocking gas bubbles, such as oxygen bubbles forming at the electrode array surface. Isolating these bubbles from the deposition electrode helps to preserve the desired component resolution of deposited materials. In some examples, the membrane is also configured to block other components (e.g., metal ions) to maintain different electrolyte compositions (e.g., anolyte and catholyte) on the opposite sides of the membrane. For example, the anolyte may comprise multivalent cations that are oxidized (e.g., Fe+2?Fe+3) thereby decreasing the oxygen gas formation.Type: ApplicationFiled: February 3, 2023Publication date: July 11, 2024Applicant: Fabric8Labs, Inc.Inventors: David Pain, Andrew Edmonds, Glenn Sklar, Kareemullah Shaik -
Publication number: 20240218546Abstract: Described herein are electrochemical-additive manufacturing (ECAM) systems comprising electrophoretically-deposited masks selectively covering a set of individually-addressable electrodes (pixels) in the electrode arrays (printheads). For example, an electrophoretically-deposited mask, comprising one or more patches, can be used to block the electric current through certain array portions thereby preventing electrolytic deposition on the corresponding portions of the deposition electrode during ECAM processes. In some examples, electrode array portions can be masked to cover damaged portions (e.g., stuck-on control circuits, electrically and/or ionically conductive passages in the electrode array) and/or to form special patterns of inactive array portions (that no longer need to be controlled using deposition control circuits). Such electrophoretically-deposited masks can be formed in an ECAM system or an external system. The mask forming can be a single-stage process or a multi-stage process.Type: ApplicationFiled: June 21, 2023Publication date: July 4, 2024Applicant: Fabric8Labs, Inc.Inventors: Sean Stone, Kareemullah Shaik, Shiv Shailendar

Publication number: 20240218545Abstract: Described herein are methods and systems for additive manufacturing of parts comprising electrolytic deposits and electrophoretic deposits. Such methods and methods provide various new ways for integrating different materials into composite parts. Specifically, an additive manufacturing system comprises an electrode array with individually-addressable electrodes. Each individually-addressable electrode is coupled to a separate deposition control circuit, which selectively connects this electrode to a power supply. When forming a composite part, the electrode array can control the location of each electrolytic deposit (by controlling the current flow through each individually-addressable electrode) and each electrophoretic deposit (by controlling the electric field distribution). An electrolyte solution or an electrophoretic suspension is provided between the electrode array and deposition electrode to form corresponding deposits.Type: ApplicationFiled: June 27, 2023Publication date: July 4, 2024Applicant: Fabric8Labs, Inc.Inventors: Michael Matthews, David Pain, Sean Stone, Kareemullah Shaik, Charles Nicholas Pateros, Shiv Shailendar
