OPTICAL FIBER CONNECTOR FOR ADDITIVE MANUFACTURING SYSTEM
Publication/Patent Number: US2020376600A1 Publication Date: 2020-12-03 Application Number: 16/884,432 Filing Date: 2020-05-27 Inventor: Aggarwal, Raghav   Feldmann martin c   Assignee: VulcanForms Inc.   IPC: B23K26/34 Abstract: Disclosed embodiments relate to additive manufacturing systems. In some embodiments, an additive manufacturing system may include a plurality of laser energy sources, an optics assembly configured to direct laser energy onto a build surface, and an optical fiber connector positioned between the plurality of laser energy sources and the optics assembly. A first plurality of optical fibers may extend between the plurality of laser energy sources and the optical fiber connector, and a second plurality of optical fibers may extend between the optical fiber connector and the optics assembly. Each optical fiber of the first plurality of optical fibers may be coupled to a corresponding optical fiber of the second plurality of optical fibers within the optical fiber connector.

Additive manufacturing systems and methods
Publication/Patent Number: US10875094B2 Publication Date: 2020-12-29 Application Number: 15/940,315 Filing Date: 2018-03-29 Inventor: Feldmann martin c   Komsta, Jan Pawel   Sweetland, Matthew   Assignee: VulcanForms Inc.   IPC: B22F3/105 Abstract: Aspects described herein relate to additive manufacturing systems and related methods. An additive manufacturing system may include two or more laser energy sources and associated optical fibers. An optics assembly may be constructed and arranged to form a rectangular laser energy pixel associated with each laser energy source. Each pixel may have a substantially uniform power density, and the pixels may be arranged to form a linear array of laser energy pixels on a build surface with no spacing between the pixels. Exposure of a portion of a layer of material on the build surface to the linear array of laser energy pixels may melt the portion of the layer.

Publication/Patent Number: US2020016657A1 Publication Date: 2020-01-16 Application Number: 16/513,702 Filing Date: 2019-07-16 Inventor: Hart, Anastasios John   Penny, Ryan Wade   Feldmann martin c   Gibbs, Jonathan S.   Baker, Stuart P.   Assignee: Massachusetts Institute of Technology   IPC: B22F3/105 Abstract: Disclosed are systems, devices, and methods for additive manufacturing that allow for control of composition and/or porosity of components being manufactured. More particularly, in exemplary embodiments, a secondary material can be used in conjunction with a primary feedstock material in a spatially controlled manner during an additive manufacturing process to control a composition of materials and/or porosity of a manufactured component. Systems, devices, and methods for additive manufacturing are also disclosed that allow for control of a pressure of an atmosphere surrounding a build surface during an additive manufacturing process. More particularly, a pressure of an atmosphere surrounding a build surface can be raised to a pressure greater than standard atmospheric pressure. Various features of the exemplary embodiments of the systems, devices, and methods disclosed can be used together to further control for composition and/or porosity and quality of a manufactured part.
