Patent number: 10562289Abstract: Method for printing a three-dimensional part layerwise with an additive manufacturing system includes printing layers by depositing material from a print head onto a print foundation, incrementing a position of the print head relative to the print foundation after each layer is printed, and indexing the print foundation carrying the printed layers away from the print head along the printing axis after a number of layers are printed. Printing is performed with driven and fixed rails clamped against movement of the print foundation. Moving the print foundation includes moving the driven rails with respect to the fixed rails in a direction substantially perpendicular to the build plane. Additive manufacturing system includes a drive mechanism to index the print foundation on the printing axis using fixed and driven rails, the driven rails engaging the print foundation for moving the print foundation.Type: GrantFiled: October 31, 2016Date of Patent: February 18, 2020Assignee: STRATASYS, INC.Inventors: Robert L. Skubic, John Bushey, Chad E. Beery, Michael D. Bosveld, Robert E. Styer

Patent number: 7891964Abstract: A pump system comprising a delivery assembly configured to feed a solid material under operational power of a first drive motor, and a screw pump comprising a housing that at least partially defines a barrel of the screw pump, an extrusion tip secured to the housing at a first end of the barrel, a liquefier secured to the housing and intersecting with the barrel, and an impeller extending at least partially through the barrel. The liquefier is configured to receive the solid material fed from the delivery assembly, to at least partially melt the received solid material, and to direct the at least partially melted material to the barrel, and the impeller is configured to drive the at least partially melted material that is directed to the barrel toward the extrusion tip under operational power of a second drive motor.Type: GrantFiled: February 11, 2008Date of Patent: February 22, 2011Assignee: Stratasys, Inc.Inventors: Robert L.

Patent number: 7297304Abstract: A method for three-dimensional modeling builds up three-dimensional objects in a heated build chamber by dispensing modeling material from a dispensing head onto a base in a predetermined pattern. Physical and thermal separation are maintained between the heated build chamber and motion control components that control the motion of the dispensing head and the base. Thermal isolation of the motion control components from the build chamber allows the chamber to be maintained at a high temperature, and has other practical advantages as well.Type: GrantFiled: November 26, 2003Date of Patent: November 20, 2007Assignee: Stratasys, Inc.Inventors: William J. Swanson, Patrick W. Turley, Paul J. Leavitt, Peter J. Karwoski, Joseph E. LaBossiere, Robert L. Skubic

Patent number: 7122246Abstract: Disclosed is a modeling filament for use as feedstock in a fused deposition modeling liquifier, and a method for manufacturing the filament. The diameter and standard deviation of the filament are controlled to meet various tolerance requirements of jam resistance, slip resistance, model strength, liquifier overflow prevention and hysteresis-free transient response. Standard deviation of the filament diameter is matched to a filament target diameter. The resulting filament is used to form high-quality models.Type: GrantFiled: February 2, 2005Date of Patent: October 17, 2006Assignee: Stratasys, Inc.Inventors: James W. Comb, William R. Priedeman, Jr., Paul J. Leavitt, Robert L. Skubic, John Samuel Batchelder

Patent number: 6722872Abstract: Disclosed is a three-dimensional modeling apparatus (10) that builds up three-dimensional objects in a heated build chamber (24) by dispensing modeling material from a dispensing head (14) onto a base (16) in a pattern determined by control signals from a controller (140). The motion control components (18, 20) of the apparatus (10) are external to and thermally isolated from the build chamber (24). A deformable thermal insulator (132) forms a ceiling of the building chamber, allowing motion control of the dispensing head (14) in an x, y plane by an x-y gantry (18) located outside of and insulated from the build chamber (24). In the preferred embodiment, a material dispensing outlet (66) of the dispensing head is inside the chamber. Thermal isolation of the motion control components from the build chamber allows the chamber to be maintained at a high temperature.Type: GrantFiled: December 13, 2001Date of Patent: April 20, 2004Assignee: Stratasys, Inc.Inventors: William J.
