Publication number: 20220212413Abstract: A method is for printing a certified part using a certified digital part file. The method has the following steps: a. Using a 3D printing apparatus and a certified digital part file to print a part according to a print process, the certified digital part file having geometry, parameters and a check data set, the check data set having criteria defining acceptable and non-acceptable levels of anomalies for successful printing of the certified part, b. During the print process, comparing print data generated by the apparatus with the check data set to indicate where a part of the printing process contains a non-acceptable anomaly. c. Where a non-acceptable anomaly is detected, using the apparatus to recover the print process by taking corrective action if possible to remove the anomaly or reduce the anomaly to an acceptable level or, where the print process is not recoverable, abandoning the print process.Type: ApplicationFiled: April 8, 2019Publication date: July 7, 2022Applicant: Aurora Labs LimitedInventors: David Budge, John Nathan Henry

Patent number: 10593515Abstract: A charged particle propagation apparatus has a generator including a vacuum chamber with a gun therein for discharging a charged particle beam through a beam exit. A higher pressure region adjoins the vacuum chamber at the beam exit and is maintainable at a pressure greater than a pressure of the vacuum chamber. A plasma interface located at the beam exit includes a plasma channel having at least three electrode plates disposed between its first end and its second end. A control system is adapted to apply a sequence of electrical currents to the electrode plates, which cause at least one plasma to move from the first end to the second end of the plasma channel, thereby pumping down the beam exit, and, in use, the charged particle beam is propagated from the vacuum chamber through the, or each, plasma into the higher pressure region.Type: GrantFiled: June 21, 2016Date of Patent: March 17, 2020Assignee: Aurora Labs LimitedInventor: David Budge
