A system for fabricating a dental restoration to restore a tooth at a restoration site in a dentition of a patient is disclosed. The dentition includes a restoration dental arch and an opposing dental arch. The restoration dental arch include the restoration site and the opposing dental arch is opposite the restoration dental arch. The system includes an impression apparatus, a motion capture apparatus, an interface apparatus, and a restoration design system. The impression apparatus is configured to capture an impression of the dentition of the patient. The motion capture apparatus is configured to capture a plurality of location data points that represent the locations of the opposing dental arch relative to the restoration dental arch. The interference model generation system is configured to generate an interference model for the restoration site. The restoration design system is for designing a restoration using the interference model.

A method and apparatus for designing and manufacturing a component in a computer-aided design and manufacturing environment is disclosed. A method includes obtaining a geometric model of a component from a geometric model database, and determining at least one orientation parameter value associated with the geometric model of the component. The at least one orientation parameter value is associated with an orientation parameter that defines orientation of the component during additive manufacturing of the component. The method includes performing volumetric analysis of the component based on the at least one orientation parameter value associated with the component using the geometric model of the component. The method also includes computing one or more overheating areas in the component corresponding to the at least one orientation parameter value based on the volumetric analysis of the geometric model of the component, and outputting a multi-dimensional visual representation of the geometric model of the component Indicating one or more overheating areas in the component.

Systems and a method determine an amount of printing material powder for 3D printing an object a multi-object printing job. Data on the following is received: a 3D-model of the object, a volume and a surface of the object, data on a thickness of a powder, on characteristics of the build chamber, a volume of a no build zone and a volume of a net build zone, an estimation of a volume of recyclable interstitial powder, on a powder density and on a solid density of the printing material and on a recycling ratio. The following quantities are determined: a volume of the powder layer around the object, a dilated object contribution, the amount of used powder due the dilated object, the amount of lost powder in the no build zone, the amount of lost powder in the net build zone and the amount of printing material required.

A digital platform enables 3D printing where the designs are protected from piracy/redistribution. A single board computer (SBC) communicates with a first server and a second server. The SBC requests a unique hardware ID from the first server, which assigns and sends the ID to the SBC. The SBC submits the ID and a secret key to the second server to request registration of a user and a printer, and the second server sends private certs, a client ID, and a unique public identifier to the SBC. The second server also receives and stores 3D print designs through a designer portal, and on-demand displays the designs in a GUI screen. The SBC user may purchase a 3D print design, and the second server, in response, sends an access token to the SBC. The SBC redeems the access token for a selected 3D print, and the second server adjusts geode for the selected 3D design for the particular printer, and streams the adjusted geode to the printer through the SBC, thereby protecting the code from unauthorized user/replication.

Methods and apparatus associated with three-dimensional objects are described. In an example, a method comprises receiving data representing a three-dimensional model object, the data comprising object model data and object property data. For at least one object property, a sub-region of the object in which the object property is non-variable is identified and, for at least one location within the object, all sub-regions in which the location is situated are identified. Based on the combination of identified sub-regions for a location, print material data is determined for the location. Control data for the production of a three-dimensional object is generated according to the print material data.
