Patent number: 11904542Abstract: A platen assembly for use with an extrusion-based 3D printer includes a grid assembly comprising at least a 4×2 framework of interlocked perpendicular x direction beams and y direction beams, providing a substantially planar upper surface and a bottom surface. The platen assembly includes a platen comprising a thin metal sheet supported on the upper surface of the grid assembly and secured to the grid assembly such that the top surface provides a substantially flat build surface. The x direction beams, the y direction beams and the platen are constructed of substantially a same thermal expansion properties, and wherein the build surface of the platen has a build surface area of at least 400 square inches and maintains its flatness to within a flatness tolerance of 0.020 inches over a temperature range of at least 20 C-300 C.Type: GrantFiled: December 4, 2020Date of Patent: February 20, 2024Assignee: Stratasys, Inc.Inventors: Jeff Lee Chapman, Robert Skubic, Bryan Migliori, Benjamin L Braton, Patrick W. Anderson, Josh Durand, Colin Schiel

Publication number: 20230382047Abstract: An extrusion-based 3D printer configured to print 3D parts in a layer-by-layer manner includes a heated build chamber, a build platen within the chamber and at least one print head configured to extrude material onto the build platen or previously extruded material wherein the at least one print head is configured to move in a print plane. The 3D printer includes at least one air intake and exhaust system that includes ductwork having an inlet configured to intake air from the build chamber and an outlet configured to exhaust air into the build chamber proximate the build plane, a fan proximate the inlet and configured to draw air into the ductwork through the inlet and propel the air towards the outlet, a heater proximate the outlet, the heater configured to heat the air as the air passes the heater and a perforated diffuser plate between the fan and the heater.Type: ApplicationFiled: May 26, 2022Publication date: November 30, 2023Inventors: Bryan Daniel Migliori, Kyra Elizabeth Neal, Benjamin L.

Patent number: 11485129Abstract: A probe for an additive manufacturing system includes a probe body having a first air port therethrough between an inlet and an outlet, and a location sensing probe extending from the probe body. The location sensing probe includes a probe end and a probe bar, the probe bar coupled between the probe body and the probe end, and a channel surrounding the probe bar, the channel having an inner tube having an inlet proximate the probe body and an outlet proximate the probe end. A method of determining a position of an item being printed in an additive manufacturing system, includes probing the position with a location sensing probe having a resolution finer than a print resolution of the print head.Type: GrantFiled: August 22, 2019Date of Patent: November 1, 2022Assignee: Stratasys, Inc.Inventors: Brent Jorgenson, Michael D. Bosveld, Logan R. Kiene, Jerome W. Goetzke, Benjamin L. Braton, David Mulcrone

Publication number: 20220288859Abstract: A method of loading filament into a 3D printer that build parts by fused deposition modeling processes includes providing a 3D printer having a receptacle configured for accepting a plug-in connector from a filament supply. The method further includes providing a filament supply having a container configured to retain a supply of a filament, a filament guide tube having a length, an inlet end attached to the container and an outlet end, and a connector at the outlet end of the filament guide tube. The connector has a geometry allowing it to be plugged into the receptacle and comprises a conduit having an entrance for accepting the outlet end of the filament guide tube and an exit for passing the filament into the printer. The method includes causing a signal to be emitted proximate the receptacle such that when the plug-in connector is inserted into the receptable, light shines through the connector to inform the operator of a filament loading status.Type: ApplicationFiled: March 11, 2021Publication date: September 15, 2022Inventors: Colin Schiel, Benjamin L. Braton, Benjamin N. Dunn, Bryan Migliori, Brett Johnson
