Publication number: 20230123528Abstract: The present disclosure relates to a system for performing an Additive Manufacturing (AM) fabrication process on a powdered material, deposited as a powder bed and forming a substrate. The system makes use of a laser for generating a laser beam, and an optical subsystem. The optical subsystem is configured to receive the laser beam and to generate an optical signal comprised of electromagnetic radiation sufficient to melt or sinter the powdered material. The optical subsystem uses a digitally controlled mask configured to pattern the optical signal as needed to melt select portions of a layer of the powdered material to form a layer of a 3D part. A power supply and at least one processor are also included for generating a plurality of different power density levels selectable based on a specific material composition, absorptivity and diameter of the powder particles, and a known thickness of the powder bed. The powdered material is used to form the 3D part in a sequential layer-by-layer process.Type: ApplicationFiled: October 20, 2022Publication date: April 20, 2023Inventors: Bassem S.

Patent number: 11444231Abstract: An energy harvesting system for collecting energy from sources of thermal energy that exist in the environment and convert the energy to electricity. The system has N-P junctions mounted on the outer surface of a conduit, pipe or flue. A hot medium flows through the conduit, pipe or flue. The p-n junctions operate as thermoelectric power generators. Heat absorbed at the p-n junctions increases the kinetic energy of charge carriers causing migration of the charge carriers. This thermally-driven migration of charge carriers is used to drive an electrical current in an external circuit.Type: GrantFiled: February 17, 2017Date of Patent: September 13, 2022Assignee: Lawrence Livermore National Security, LLCInventors: Joseph C.
