Abstract: In various implementations, three-dimensional ("3D") data representing a physical structure may be received (402), e.g., from sensor(s) (101) or elsewhere. The 3D data may include an orientation of the physical structure and/or a spatial measurement of the physical structure. Based on the 3D data, a data structure may be generated (404) representing a virtual 3D model of the physical structure. A virtual scale may be incorporated (408) with the data structure representing the virtual 3D model of the physical structure that conveys one or both of the orientation and the spatial measurement. The virtual scale may be distorted directly in proportion with any distortion of the virtual 3D model of the physical structure. The data structure may be printable, using a 3D printer (110), to create a physical model (112, 212) of the physical structure that includes a physical manifestation (114, 214, 314) of the virtual scale.

Abstract: According to examples, a three-dimensional (3D) fabrication system may include fabrication components and a controller. The controller may control the fabrication components to fabricate parts of a 3D object in a build envelope, the parts to be assembled together to form the object, and in which the parts are fabricated at locations corresponding to relative positions of the parts with respect to each other in the assembled object. The controller may also control the fabrication components to fabricate a cage around the parts in the build envelope.

Abstract: The present invention relates to an additive manufacturing method and apparatus that is configured to construct a mold in additive layers, and a three-dimensional object therein in layers equal to or thicker than the mold construction layers. Without a powder bed needed, the mold defines the geometry, dimensions and surface finish of a three-dimensional object manufactured, so that in the process an energy source or combined sources can be selected from a large group for fusion, sintering, consolidating, joining, curing, or hardening in processing different forms and types of feedstock materials to manufacture metallic, polymeric or composite objects or parts.

Abstract: A method of chemical process intensification by designing a chemical process component through modeling using dimensionless numbers. The method comprises identifying the inter-relationship between chemical process engineering parameters and structures for subcomponents of the chemical process component, defining a weighting among a plurality of dimensionless numbers associated with a processing function of the subcomponents, simulating a chemical process for each of a plurality of combinations of subcomponent designs to determine, for each combination, a value for each of the plurality of the dimensionless numbers, determining a simulation score for each simulated chemical process based on the plurality of dimensionless numbers determined for that simulated chemical process and based on the defined weighting among the plurality of dimensionless numbers, and selecting a combination of subcomponent designs associated with an extreme simulation scores.
