Abstract: In an example, a method includes receiving object model data describing at least a portion of an object to be generated by additive manufacturing. Object generation instructions for generating the object in its entirety may be derived based on the object model data. Where it is determined that the object model data comprises a data deficiency for deriving the object generation instructions, at least one attribute for the object may be inferred and object generation instructions may be derived based on the object model data and the inferred attribute.

Abstract: Examples analyze three-dimensional printing specifications associated with a three-dimensional printing device to determine test angles for a test object and test surfaces corresponding to the test angles for the test object. Examples generate the test object for color calibration for the three-dimensional printing device based at least in part on the test angles and test surfaces that are configured with at least one test color.

Abstract: Examples of methods are described. In some examples, a method includes generating, using a first branch of a machine learning model, a first agent map based on a layer image. In some examples, the method includes generating, using a second branch of the machine learning model, a second agent map. In some examples, the first agent map and the second agent map indicate printing locations for different agents.

Abstract: Examples of methods are described. In some examples, a method includes determining, using a variational autoencoder model, a latent space representation. In some examples, the latent space representation is of object model data. In some examples, the method includes predicting manufacturing powder degradation. In some examples, predicting the manufacturing powder degradation is based on the latent space representation.

Abstract: In a 3D printing method example, color is added to a part. A build material is applied, and is pre-heated to a temperature ranging from about 50 C to about 400 C. A black ink, including an infrared absorbing colorant, is selectively applied on at least a portion of the build material. A white ink, including a white colorant that is opaque in visible wavelengths and is transparent to infrared wavelengths, is selectively applied on the black ink. A colored ink, including a colorant having a color other than black or white, is selectively applied on the white ink. The build material and the applied inks are then exposed to infrared radiation. The black ink at least partially fuses the portion of the build material in contact therewith. At least some of the white colorant and the colorant are embedded in the at least partially fused portion at a surface thereof.

Abstract: In an example, an apparatus for generating a three-dimensional object includes a build area platform, a build material distributor, a secondary material ejection device, a coalescing agent ejection device, and a controller. The controller may control the secondary material ejection device to eject a secondary material in a predefined pattern over the build area platform, control the build material distributor to distribute a layer of the build material around the ejected secondary material, control the coalescing agent ejection device to eject the coalescing agent onto the layer of the build material, and control an energy source to apply energy onto the ejected coalescing agent to cause the build material in contact with the ejected coalescing agent to coalesce and solidify.

Abstract: An example of a penetrating agent for a three-dimensional (3D) printing process includes a surfactant blend, a co-solvent, a humectant present in an amount ranging from about 2 wt % to about 10 wt %, based on a total weight of the penetrating agent, and a balance of water. The surfactant blend includes a first non-ionic surfactant having a first hydrophilic chain length, a second non-ionic surfactant, wherein the second non-ionic surfactant is selected from the group consisting of a polyether siloxane and an alkoxylated alcohol, and an anionic surfactant.

Abstract: Examples of a cosmetic agent are for three-dimensional (3D) printing. In an example, the cosmetic agent includes a dye, an oxidizing agent, and a solvent. The oxidizing agent is to react with an antioxidant in a build material to reduce reduction of the dye in the presence of the antioxidant.

Abstract: An agent distributor may be to selectively deliver agent at a first contone density and at a second contone density different from the first contone density respectively onto an interior portion and a surface portion of successive layers of build material in respective first and second patterns in accordance with data representing a three-dimensional object to be generated, so that the build material is to solidify to form slices of the three-dimensional object in accordance with the first and second patterns, and so that the three-dimensional object is to achieve a target surface roughness as a result of the second contone density of the second pattern.
