Patent number: 10773511Abstract: An extruder is fitted with a connector for coupling and decoupling with a filament feed source, such as a filament tube. When connected, the extruder and filament tube are aligned to define a feed path for a filament. A tool rack includes a plurality of filament tubes secured within respective openings. The tool rack may facilitate coupling and decoupling operations between the extruder and filament sources. For example, the tool rack may define an insertion path that engages a filament tube during insertion, and that secures the filament tube against an excursion from the insertion path. The extruder may disengage the coupling by initiating a motion along the insertion path and then moving off of the insertion path to decouple the filament tube and the extruder. In this manner, filaments may be swapped through engaging and disengaging the extruder with different filament tubes on the tool rack.Type: GrantFiled: November 7, 2019Date of Patent: September 15, 2020Assignee: MakerBot Industries, LLCInventors: Samuel Holland, Mark Waller, Carlos Fernandez Arreola, Vishnu Anantha

Patent number: 10556381Abstract: An extruder or other tool head of a three-dimensional printer is instrumented to detect contact force against the extruder, such as by a build platform or an object being fabricated. The tool head may also be instrumented to detect deflection forces and the like acting on the tool that might indicate an operating error. The resulting feedback data can be used in a variety of ways to control operation of the three-dimensional printer during fabrication or diagnostics.Type: GrantFiled: October 26, 2015Date of Patent: February 11, 2020Assignee: MakerBot Industries, LLCInventors: Aljosa Kemperle, Filipp Gelman, Peter Joseph Schmehl

Patent number: 10532552Abstract: Linear lengths of build material are initially deposited spaced apart from one another, with the resulting gaps or offsets filled in by subsequent deposition passes. In this manner, each straight length of material can cool independently before bonding to other adjacent lengths of material, thereby avoiding or mitigating non-axial stresses on each linear length of material as it cools.Type: GrantFiled: October 21, 2016Date of Patent: January 14, 2020Assignee: MakerBot Industries, LLCInventor: Andrey V. Patrov

Patent number: 10532511Abstract: In an aspect, infilling includes one or more the following characteristics: (i) adjacent rows and columns, which may be overlapping or non-overlapping; (ii) no sharp angle turns, i.e., no turns of ninety degree or less; and (iii) intersecting between infill patterns occurs from layer to layer (i.e., at offset z-axis positions). An infilling technique may also or instead include rotating the infill pattern about ninety degrees in some alternating fashion from layer to layer.Type: GrantFiled: May 27, 2016Date of Patent: January 14, 2020Assignee: MakerBot Industries, LLCInventor: Andrey V.

Patent number: 10525692Abstract: An extruder or other similar tool head of a three-dimensional printer is slidably mounted along a feedpath of build material so that the extruder can move into and out of contact with a build surface according to whether build material is being extruded. The extruder may be spring-biased against the forward feedpath so that the extruder remains above the build surface in the absence of applied forces, and then moves downward into a position for extrusion when build material is fed into the extruder. In another aspect, modular tool heads are disclosed that can be automatically coupled to and removed from the three-dimensional printer by a suitable robotics system. A tool crib may be provided to store multiple tool heads while not in use.Type: GrantFiled: October 24, 2018Date of Patent: January 7, 2020Assignee: MakerBot Industries, LLCInventors: Peter Joseph Schmehl, Aljosa Kemperle, Stewart Schmehl

Patent number: 10421238Abstract: The hardware and software properties of a three-dimensional printer can be queried and applied to select suitable directly printable models for the printer, or to identify situations where a new machine-ready model must be generated. The properties may be any properties relevant to fabrication including, e.g., physical properties of the printer, printer firmware, user settings, hardware configurations, and so forth. A printer may respond to configuration queries with a dictionary of capabilities or properties, and this dictionary may be used to select suitable models, or determine when a new model must be created. Similarly, when a printable model is sent to the printer, metadata for the printable model may be compared to printer properties in the dictionary to ensure that the model can be fabricated by the printer.Type: GrantFiled: December 31, 2014Date of Patent: September 24, 2019Assignee: MakerBot Industries, LLCInventors: Alison N.

Patent number: 10315358Abstract: Three-dimensional printer fabrication is improved by receiving a digital model of an object specifying two or more different build materials, prioritizing the different build materials with a ranking, identifying exclusive locations where a surface layer of the object has one of the build materials, generating an external structure for the object according to one or more design rules, matching a first build material of the external structure to a second build material of the object at each of the exclusive locations, the matching based on at least one shared property of the materials, generating tool instructions for fabricating the object and the external structure, the tool instructions including one or more selections between the first build material and the second build material based upon the ranking and the matching, and controlling the three-dimensional printer according to the tool instructions to fabricate the object and the external structure.Type: GrantFiled: March 27, 2018Date of Patent: June 11, 2019Assignee: MakerBot Industries, LLCInventors: Joseph Sadusk, Filipp Gelman

Patent number: 10286646Abstract: A raft to support a three-dimensional object on a build platform of a three-dimensional printer can be fabricated with a controlled adhesion pattern to improve overall raft performance. For improved raft-to-build platform adhesion, an exterior portion around the perimeter of the raft may be fabricated with greater adhesion (per unit of surface area covered by the exterior portion) than an interior portion. This can be accomplished by varying the volume of build material, varying the printing height, or using different patterns of build material. At the same time, adhesion of the raft to a printed object built thereon can be controlled with a number of techniques such as using specific build patterns for the top layer of the raft or varying printing heights (e.g., z-axis position) between the top of the raft and the bottom of the object.Type: GrantFiled: December 22, 2016Date of Patent: May 14, 2019Assignee: MakerBot Industries, LLCInventors: Michael Vincent Zappitello, Kevin C. Rand, Andrey V. Patrov, Justy E. Alicea, Gregory M. Studer

Patent number: 10201929Abstract: The strength of a bond between two adjacent layers of a three-dimensional print is weakened by initiating fabrication of a top layer at a height greater than the processing height for the print. This technique may be used in particular at the interface between a raft or other support and an object being fabricated, after which the printing process may return to a regular process height for additional layers used to fabricate the remainder of the object.Type: GrantFiled: June 12, 2014Date of Patent: February 12, 2019Assignee: MakerBot Industries, LLCInventors: Joseph Sadusk, Filipp Gelman

Patent number: 10150248Abstract: A server is configured to store a number of different models of an object in machine-ready form corresponding to a number of different three-dimensional printers having differing capabilities and/or hardware configurations. When a user at a client device or a printer requests the object, the server automatically determines a printer type and selects a suitable, corresponding machine-ready model for immediate fabrication by the printer.Type: GrantFiled: June 20, 2018Date of Patent: December 11, 2018Assignee: MakerBot Industries, LLCInventors: Nathaniel B.
