Patent number: 11407027Abstract: A debinder provides for debinding printed green parts in an additive manufacturing system. The debinder can include a storage chamber, a process chamber, a distill chamber, a waste chamber, and a condenser. The storage chamber stores a liquid solvent for debinding the green part. The process chamber debinds the green part using a volume of the liquid solvent transferred from the storage chamber. The distill chamber collects a solution drained from the process chamber and produces a solvent vapor from the solution. The condenser condenses the solvent vapor to the liquid solvent and transfer the liquid solvent to the storage chamber. The waste chamber collects a waste component of the solution.Type: GrantFiled: October 29, 2019Date of Patent: August 9, 2022Assignee: Desktop Metal, Inc.Inventors: Daniel R. Jepeal, Paul E. Dresens

Patent number: 10288052Abstract: A helium management control system for controlling the helium refrigerant supply from a common manifold supplies cryogenic refrigerators with an appropriate helium supply. The system employs sensors to monitor and regulate the overall refrigerant supply to deliver an appropriate refrigerant supply to each of the cryogenic refrigerators depending on the computed aggregate cooling demand of all of the cryogenic refrigerators. An appropriate supply of helium is distributed to each cryopump by sensing excess and sparse helium and redistributing refrigerant accordingly. If the total refrigeration supply exceeds the demand, or consumption, excess refrigerant is directed to cryogenic refrigerators which can utilize the excess helium to complete a current cooling function more quickly.Type: GrantFiled: April 29, 2016Date of Patent: May 14, 2019Assignee: Brooks Automation, Inc.Inventors: Paul E. Dresens, Gary S. Ash, Allen J. Bartlett, Bruce R. Andeen, Y. Roberto Than, Joseph Chopy, Jr.
