Abstract: A system is provided for securely performing 3D printing. The system includes: (a) computing equipment configured to: (1) display a list of items available for 3D printing to a user; (2) receive a selection from the user of a particular item; (3) authenticate an acquisition of the particular item by the user; and (4) send, to a 3D printer of the user, a secure 3D print file that includes a description of 3D geometry of the particular item, a description of access restrictions for 3D printing of the particular item, and secure access controls preventing unauthorized access to 3D printing of the particular item; and (b) the 3D printer configured to: (1) authenticate that the user has acquired the particular item and validate that the access restrictions for 3D printing of the particular item do not restrict 3D printing of the particular item by the 3D printer; and (2) in response to authenticating and validating, construct the particular item using the description of 3D geometry of the particular item.

Abstract: A 3D printing apparatus and method determines features based on design data of an object and at least one classification of a determined feature. The at least one classification includes a classification that the determined feature is a critical feature for the object. At least one print setting for forming the determined feature is modified based on the classification that the determined feature is a critical feature.

Abstract: A 3D printing apparatus and method confirms that one or more print parameters was satisfied in the printing of a 3D object. Sensor readings are obtained during the printing of the 3D object. Based on sensor data corresponding to the sensor readings, a confirmation is made as to whether the one or more print parameters was satisfied in the printing of the 3D object.

Abstract: According to aspects, provided is a method for displaying a three-dimensional geometry of a part to be 3D printed, comprising receiving the geometry of a part sliced into shells or layers, displaying the shells or layers, displaying, for a shell or layer, a representation of a distribution of a isotropic fill material, displaying, for an anisotropic fill subset of the set of shells or layers, a representation of a distribution of an anisotropic fill material having an anisotropic characteristic oriented relative to a trajectory of an anisotropic fill tool path, receiving a selection, from among the displayed shells or layers, of an editing subset, the editing subset including part of the anisotropic fill subset, and regenerating, for a shell or layer of the editing subset, one of a second representation of a distribution of isotropic fill material and a second representation of a distribution of anisotropic fill material.

Abstract: A 3D printing apparatus and method corrects for skew in the motion components of the apparatus without the use of an independent reference object. A calibration object having features therein or thereon is printed. A user rotates the calibration object by a certain angle after it is printed. The features in/on the calibration object are measured, and an amount of skew is determined based on the measurements. In addition, a 3D printing operation is compensated based on the effects of a coefficient of thermal expansion and/or moisture absorption on dimensional changes.

Abstract: A three-dimensional geometry is received, and sliced into layers. A first anisotropic fill tool path for controlling a three dimensional printer to deposit a substantially anisotropic fill material is generated defining at least part of an interior of a first layer. A second anisotropic fill tool path for controlling a three dimensional printer to deposit the substantially anisotropic fill material defines at least part of an interior of a second layer. A generated isotropic fill material tool path defines at least part of a perimeter and at least part of an interior of a third layer intervening between the first and second layers.

Abstract: In a 3D composite printer, toolpaths defining fill material shells are received, as are toolpaths defining support material shells. A 3D toolpath defining a long fiber composite material curved shell is also received. A fill material deposition head traces the toolpaths to deposit some of the fill material shells or support material shells at least in part non-parallel to a printing substrate. A long fiber deposition head traces the 3D toolpath at least in part non-parallel to the printing substrate to deposit the long fiber composite material curved, concave, ring, tube, or winding shells to enclose, surround, or envelop at least a portion of the fill or support material shells.
