Patent number: 12654394Abstract: An apparatus for producing a three-dimensional object includes a support assembly having a build platform, a track extending through a build area, and a deposition mechanism mounted on the track and configured for producing the three-dimensional object in a layer-by-layer technique. The deposition mechanism includes a carriage moveable along the track, a supply of a flowable material mounted on the carriage, a roller in communication with the flowable material, where the roller is rotatably mounted on the carriage and configured for rotating to carry the flowable resin to an application for application to produce the object, and an exposure device mounted on the carriage. The exposure device emits electromagnetic waves to an exposure site to solidify the applied flowable material to produce the object. The roller is permeable to the electromagnetic waves, such that the waves pass through the roller in traveling from the exposure device to the exposure site.Type: GrantFiled: January 13, 2023Date of Patent: June 16, 2026Assignee: PAXIS LLCInventors: Frederick Knecht, Michael G.

Patent number: 12565001Abstract: An assembly for supplying a resin or other flowable material includes a supply vat configured to contain the flowable material, and a roller positioned at least partially within the supply vat and configured to be in contact with the flowable material. The roller has a cylindrical outer surface to carry the flowable material out of the supply vat for application to produce an object. The supply vat has an inner support wall, with a space is defined outward of the inner support wall, and the inner support wall has an opening therethrough extending between the supply vat and the space. The roller extends through the opening, and a seal is engaged with the roller around an entire periphery of the cylindrical outer surface of the roller and positioned adjacent the opening to resist most leakage of the flowable material through the opening.Type: GrantFiled: July 18, 2022Date of Patent: March 3, 2026Assignee: PAXIS LLCInventors: Frederick Knecht, Michael G.

Patent number: 12358222Abstract: A deposition mechanism is configured for producing a three-dimensional object within a build area using a flowable material in a layer-by-layer technique, and includes an exposure device configured for emitting electromagnetic waves, the exposure device having an array of outlets configured for emitting electromagnetic waves toward an exposure site to solidify applied flowable material to produce the three-dimensional object, and a lens array positioned between the outlets of the exposure device and the exposure site and configured to focus the electromagnetic waves exiting the outlets toward the exposure site, where the lens array includes a plurality of ball lenses, each ball lens configured to reduce an image formed by the electromagnetic waves passing through the respective ball lens. The exposure device may include circuit boards, each having a plurality of light emitting devices connected thereto, and optical fibers extending from the light emitting devices to form the array of outlets.Type: GrantFiled: August 16, 2021Date of Patent: July 15, 2025Assignee: PAXIS LLCInventors: Frederick Knecht, Michael G.
