Publication number: 20230258575Abstract: An additive manufacturing system comprises an apparatus arranged to distribute layer of metallic powder across a build plane and a power source arranged to emit a beam of energy at the build plane and fuse the metallic powder into a portion of a part. The system includes a processor configured to steer the beam of energy across the build plane and receive data generated by one or more sensors that detect electromagnetic energy emitted from the build plane when the beam of energy fuses the metallic powder. The received data is converted into one or more parameters that indicate one or more conditions at the build plane while the beam of energy fuses the metallic powder. The one or more parameters are used as input into a machine learning algorithm to detect one or more defects in the fused metallic powder.Type: ApplicationFiled: November 17, 2022Publication date: August 17, 2023Applicant: Sigma Labs, Inc.Inventors: Darren Beckett, Roger Frye, Christina Xuan Yu, Scott Betts, Lars Jacquemetton, Kevin C.

SYSTEMS AND METHODS FOR MEASURING RADIATED THERMAL ENERGY DURING AN ADDITIVE MANUFACTURING OPERATION
Publication number: 20220324056Abstract: This disclosure describes various methods and apparatus for characterizing an additive manufacturing process. A method for characterizing the additive manufacturing process can include generating scans of an energy source across a build plane; measuring an amount of energy radiated from the build plane during each of the scans using an optical sensing system that monitors two discrete wavelengths associated with a blackbody radiation curve of the layer of powder; determining temperature variations for an area of the build plane traversed by the scans based upon a ratio of sensor readings taken at the two discrete wavelengths; determining that the temperature variations are outside a threshold range of values; and thereafter, adjusting subsequent scans of the energy source across or proximate the area of the build plane.Type: ApplicationFiled: June 22, 2022Publication date: October 13, 2022Applicant: Sigma Labs, Inc.Inventors: Darren Beckett, Scott Betts, Martin Piltch, R.

Publication number: 20210138578Abstract: An additive manufacturing system comprises a build plane and an energy source configured to direct energy onto a work region of the build plane. An optical detector is configured to receive one or more optical signals from the work region. An optical filter is positioned between the work region and the optical detector, wherein the optical filter includes a first partially transmissive polarized filter having a first polarization axis and a second partially transmissive polarized filter having a second polarization axis. The first polarization axis is rotationally offset from the second polarization axis approximately 90 degrees. The optical filter improves the signal to noise ratio of the optical sensors.Type: ApplicationFiled: November 6, 2020Publication date: May 13, 2021Applicant: SIGMA LABS, INC.Inventors: Darren Beckett, Martin S.
