Abstract: Examples described herein relate to a system consistent with the disclosure. For instance, the system may comprise an additive manufacturing device including hardware to form a three-dimensional (3D) model, a memory resource, and a processing resource to receive data related to the 3D model, modify the data related to the 3D model to include a protective structure connected to the 3D model by a fusion bond, and dispense, based on the modified data, a printing agent onto build material layers to produce the 3D model and the protective structure around a portion of the 3D model.

Abstract: An example system includes a feature extraction engine. The feature extraction engine is to determine a plurality of scale-dependent features for a portion of a target. The system also includes a signature-generation engine to select a subset of the plurality of scale-dependent features based on a strength of each feature. The signature-generation engine also is to store a numeric representation of the portion of the target and the subset of the plurality of scale-dependent features.

Abstract: A surface including: multiple data pages, wherein each data page includes: multiple optically detectable marks indicating boundaries of the data page; and an array of data cells, wherein a location of an optically detectable mark in a data cell of the array of data cells encodes information and adjacent data pages use different encoding patterns such that an encoded value would be represented by a first pattern of marks on a first data page and the same encoded value would be represented by a second, different pattern of marks on a second data page.

Abstract: Methods of generating a three-dimensional object with an additive manufacturing system are described. The method includes depositing a build material within a working area, thereby providing a build material layer, selectively depositing a fusing agent onto a portion of the build material layer, applying energy from a bulk-fusion energy source to the working area, thereby fusing at least a portion of the build material where the fusing agent is deposited, and applying energy from a focused energy source to one or more localized areas of the working area.

Abstract: A method is disclosed. The method comprises defining a region of interest on a three-dimensional model of an object. The method may comprise capturing an image of an object manufactured according to the three-dimensional model. The method may comprise determining, using a processor, a position and orientation of the three-dimensional model with respect to the object in the captured image. The method may comprise locating the region of interest on the manufactured object. A portion of the manufactured object within the region of interest may comprise an identifiable feature. An apparatus and a machine-readable medium are also disclosed.

Abstract: A method comprises moving a robotic structure to a first pose such that an end-effector of the robotic structure has an absolute position comprising an absolute location and absolute orientation. The method comprises providing a calibration artefact on the end-effector. The method comprises determining at least three planes coinciding with at least three respective surface planes of the calibration artefact, by measuring absolute locations of a plurality of points on the calibration artefact. The method comprises determining the absolute location and absolute orientation of the end-effector, when the robotic structure is in the position based on the determined at least three planes. The method also comprises calibrating the first pose of the robotic structure using the determined absolute location and absolute orientation of the end-effector.
