Disclosed is a shaping system for shaping a three-dimensional object, which includes a slice data generation step that generates slice data and a shaping execution step that shapes the three-dimensional object by a shaping apparatus based on the slice data. The shaping apparatus shapes the three-dimensional object using inkjet heads. The slice data generation step has a color cross-section data generation step that generates color cross-section data showing at least a cross-sectional shape of the three-dimensional object and a color at each position, a plate division data generation step that generates plate division cross-section data in which the color cross-section data is color-separated for each color of the material, and a plate division cross-section data change step that changes at least some plate division cross-section data. The slice data is generated based on the plate division cross-section data changed in the plate division cross-section data change step.

Systems for fabricating dental appliances are provided. In some embodiments, a system comprising one or more processors, and a memory operably coupled to the one or more processors and storing instructions that, when executed by the one or more processors, cause the system to determine an appliance geometry for a dental appliance including a shell configured to move the patient's teeth from an initial arrangement toward a target arrangement. The appliance geometry can include a first power arm having a first connection point for connecting to the shell, a second power arm having a second connection point for connecting to the shell or to a tooth, an elongate connecting structure coupled to the first and second power arms, and an elongate counter-force connector coupled to the first power arm and extending toward the second power arm.

A three-dimensional shaping apparatus includes a melting section providing a shaping material to a channel, a nozzle ejecting the shaping material to a shaping region of a shaping table, an ejection-amount adjusting mechanism adjusting an amount of the shaping material from the nozzle, a suction member sucking the shaping material in the channel, a memory configured to store a program, and a processor configured to execute the program so as to control the three-dimensional shaping apparatus. The processor is configured to stop the ejection of the shaping material and, thereafter, prior to resumption of the ejection of the shaping material, execute material purge processing for discharging the shaping material remaining in the melting section to a region different from the shaping region. The suction member is located closer to the nozzle than the ejection-amount adjusting mechanism in the first channel.

A virtual build of an assembly may be performed by operating a virtual build tool inside of an active session of design software that is configured to design an assembly having multiple individual parts; importing characteristics of the assembly from a three-dimensional (3D) model of the assembly that is maintained by the design software; receiving an input of sequence numbers that indicate an assembly order for the individual parts; generating images for the individual parts as they are incrementally added to the assembly based on the sequence numbers; and generating a set of build instructions based on the sequence numbers and the images for the individual parts, where the set of build instructions illustrate how to physically manufacture the assembly.

A method of configuring robot fleets with additive manufacturing capabilities includes receiving a request for a robotic fleet to perform a job and determining a job definition data structure based on the request. The job definition data structure defines a set of tasks to be performed in furtherance of the job. The method includes determining a provisioning configuration for each additive manufacturing system based on the task to which the additive manufacturing system is assigned, the set of 3D printing requirements, the printing instructions, and the status of the additive manufacturing system. The method includes provisioning the additive manufacturing system based on the provisioning configuration and a set of additive manufacturing system provisioning rules that are accessible to an intelligence layer to ensure that provisioned systems comply with the provisioning rules. The method includes deploying the robotic fleet based on the robotic fleet configuration data structure to perform the job.

Methods and systems for digitally designing a plurality of aligners are provided. In some embodiments, a method includes receiving an intraoral scan of the patient's teeth, and generating 3D dental model of the patient's teeth using the intraoral scan. The method can include identifying a movement path to move the patient's teeth from an initial arrangement toward a target arrangement through a plurality of intermediate arrangements in accordance with a treatment plan. The method can also include identifying one or more appliance features of at least one aligner, the one or more appliance features including one or more feature regions having one or more feature thicknesses. The method can further include instructing an additive manufacturing machine to directly fabricate the at least one aligner in a layer-by-layer fashion.

A system and computer-implemented method for manufacturing an orthopedic implant involves segmenting features in an image of anatomy. Anatomic elements can be isolated. Spatial relationships between the isolated anatomic elements can be manipulated. Negative space between anatomic elements is mapped before and/or after manipulating the spatial relationships. At least a portion of the negative space can be filled with a virtual implant. The virtual implant can be used to design and manufacture a physical implant.

A method for providing control data for manufacturing at least one three-dimensional object by means of a layer-wise solidification of a building material in an additive manufacturing apparatus is provided. The method includes at least the following steps: a) determining the locations corresponding to the cross section of the at least one object, b) determining at least two different regions to be solidified in said at least one layer, wherein said at least two regions are chosen from the group of: sandwiched region, down-facing region and up-facing region, c) defining a scanning sequence for the beam so as to solidify the building material at least at the locations corresponding to said portion of the cross section of the object, wherein at an interface between a first and a second region differing from each other a scan line of the beam is continuous and at least one beam parameter value is changed.
