Abstract: Examples disclosed herein relate to a finishing system for a three-dimensional (3D) printed part. Example systems include a sensor to detect a marking on a portion of the 3D printed part. A post-processing component of the system may perform a finishing operation on the portion of the 3D printed part while the marking is detected on the 3D printed part.

Abstract: According to one aspect, there is provided a method of forming a layer of build material on a build platform of a three-dimensional printing system. The method comprises obtaining characteristics of a build volume to be processed, determining characteristics of a volume of build material to be used to form the layer, forming an intermediate volume of build material having the determined characteristics, and spreading the intermediate volume of build material over the build platform to form the layer.

Abstract: According to an example, in a method for forming a three-dimensional (3D) printed object, a plurality of layers of the 3D printed object and a channel that extends through the plurality of layers may be formed, in which the plurality of layers is formed of a first material. In addition, a supporting element may be inserted into the channel such that the supporting element extends through multiple layers of the plurality of layers, in which the supporting element is formed of a second material that differs from the first material.

Abstract: A method assigns one or more attributes of a part to be manufactured, based on received part data. A printability score and cost estimate of manufacturing the part is made.

Abstract: A three-dimensional (3D) printing device includes a processor and memory communicatively coupled to the processor. The processor verifies that a digital contract certified by an authorized party is authentic and applicable. The digital contract includes a process bound, a part bound for each part in a packed bed of parts, a time bound, and a cost identifier to define a cost of printing the packed bed that is based on the process bound, the part bound for each part in the packed bed of parts, and the time bound.

Abstract: Some examples include a computer-readable medium storing executable instructions which, when executed by a processor, are to cause the processor to receive electronic data describing a part to be manufactured in a three-dimensional additive manufacturing process; develop instructions using the electronic data for creating an outer layer on a surface of the part in the additive manufacturing process, where the outer layer having a physical property that differs from that of the surface of the part; and manufacture the part using the instructions.

Abstract: Private data to be communicated to a recipient is encrypted with the public key of a public and private key pair associated with the recipient. An optically readable format of the encrypted private data is generated. The optically readable format may be provided to the recipient.

Abstract: According to an example, an apparatus may include a hardware processor that is to access a first scanned image, in which the first scanned image corresponds to a scanned first feature of a three-dimensional (3D) object, perform a search for models matching the 3D object based upon the first scanned image, identify, from the search, a first set of candidate models, identify, from the first set of candidate models, a general identity of the 3D object, determine, based upon the identified general identity of the 3D object, a second feature of the 3D object that is to be scanned, and output an instruction to obtain a second scanned image of the determined second feature of the 3D object.

Abstract: Example implementations relate to computing devices with movable input/output (I/O) connectors. For example, a computing device may include a chassis of the computing device and an I/O connector to connect an I/O device to the computing device. The I/O connector may be movable about an axis relative to the chassis by at least 180 degrees such that the I/O connector is accessible from multiple sides of the chassis.
