Patent number: 11325305Abstract: A build plate for 3D printers that facilitates separation of the workpiece from the build plate and yet provides lateral anchoring of the unit cell. The build plate comprises (1) a foundation of a material that the unit cell material will not adhere to or will only weakly adhere to, and (2) a plurality of adhesive islands that provide a lateral anchor for the unit cell. An adhesive island is a hole in the foundation of the build plate that is filled with a plug of material to which the unit cell material will strongly adhere. The number, type, location, and size of the adhesive islands is tailored to provide enough lateral stability where needed, but not more.Type: GrantFiled: July 26, 2019Date of Patent: May 10, 2022Assignee: Arevo, Inc.Inventors: Zachary Aaron August, Christopher Thomas Lee

Publication number: 20210154934Abstract: A pair of physically-integrated two-stage heaters are disclosed for precisely heating a thermoplastic filament and a thermoplastic workpiece in preparation for depositing the filament onto the workpiece. The design in physically compact and capable of heating the filament and workpiece to within a very narrow temperature range. This is accomplished with four independently-generated light beams, of different frequencies, that are spatially combined and transmitted, via optical fiber or free-space optics, to the location where they are needed and where they are unpacked (i.e., spatially separated) and shone onto their respective targets.Type: ApplicationFiled: November 21, 2019Publication date: May 27, 2021Applicant: Arevo, Inc.Inventors: Leonid Michael Treyger, Zachary Aaron August, Hemant Bheda

Patent number: 10926463Abstract: A filament guide that guides thermoplastic filament to an object being manufactured. A deposition head comprising the disclosed filament guide provides a filament to the intended deposition point. The filament guide comprises a guide member having a filament groove configured to guide the filament along a path of travel. The groove has an upstream end that is configured to receive the filament from a source and a downstream end that is configured to direct the filament toward the deposition point in the intended direction. A notch at the downstream end of the guide member enables the filament to travel toward the deposition point. The portions of the guide member on either side of the notch act to keep the filament centered laterally. A plate that is transparent to electromagnetic radiation from a heat source covers the groove and permits the electromagnetic radiation to reach the filament while providing added support.Type: GrantFiled: April 9, 2018Date of Patent: February 23, 2021Assignee: Arevo, Inc.Inventors: Zachary Aaron August, Erik Oscar Sunden
