Abstract: A method of custom print mode generation in a three-dimensional (3D) printing device may include printing a plurality of parts with a plurality of 3D printing devices, the parts each being printed using different process parameters, and capturing a plurality of images of the parts. The method may also include, with an image analysis module, analyzing the images to classify the parts into a plurality of defect gradings, and adjusting a number of the process parameters based on characteristics of the parts identified by a user as undesirable. The examiner may also include, with a recommending module, creating a custom print mode based on the parts defect gradings and adjusted process parameters.

Abstract: Examples of methods for object deformation determination are described herein. In some examples, a method includes aligning a first bounding box of a three-dimensional (3D) object model with a second bounding box of a scan. In some examples, the method includes determining a deformation between the 3D object model and the scan based on the alignment.

Abstract: Examples of methods for object packings are described herein. In some examples, a method includes generating chromosomes in a genetic procedure. In some examples, each chromosome indicates a packing of objects in a volume. In some examples, the method also includes determining uniformity scores corresponding to the chromosomes. In some examples, each uniformity score is based on object orientation similarity. In some examples, the method further includes selecting a chromosome based on the uniformity scores.

Abstract: Examples of methods for determining chromosome expiration are described herein. In some examples, a method includes generating, in a genetic procedure, chromosomes indicating object packing positions. In some examples, the method includes determining whether a chromosome of the chromosomes is expired. In some examples, the method includes excluding the chromosome from a subsequent generation in response to determining that the chromosome is expired.

Abstract: Examples of methods for determining object packings are described herein. In some examples, a method includes determining, for each of a plurality of objects, an initial orientation corresponding to a minimum bounding box. In some examples, the method includes determining a packing of the plurality of objects using the initial orientations with a genetic procedure.

Abstract: In an example, a collection of compute resources corresponding to a class of devices is identified with a request and a synthesis routine is performed via a number of destinations corresponding to the class of devices. In an example, a type of compute resource to use with an operation of a request is determined, a device with the type of compute resource determined for the operation of the request is identified; the identified device performs the operation of the request within a bounds of a policy, and a result of the operation is communicated to a remote storage location.

Abstract: Examples of a thermal behavior prediction method are described herein. In some examples of the thermal behavior prediction method, a predicted heat map of a layer corresponding to a three-dimensional (3D) model is computed using at least one neural network. The predicted heat map is computed based on a contone map corresponding to the 3D model.

Abstract: In an example, a method includes receiving, at a processor, object model data representing at least a portion of an object to be generated by an additive manufacturing apparatus by fusing build material. Using a processor and from the object model data, a property diffusion model for the object in object generation may be determined. Using a processor and based on the property diffusion model, a manufacturing boundary object shell around the object and encompassing an external volume may be determined. The shell may have a variable thickness determined so as to include build material for which, in generation of the object, the property modelled in the property diffusion model has a value which is predicted to conform to a predetermined parameter.

Abstract: In some examples, a distribution of values of a property of a given layer to be printed as part of three-dimensional (3D) printing is predicted, wherein the predicting is based on a distribution of values of the property in a previous layer that has been printed as part of the 3D printing. 3D printing of an object is controlled based on the predicted distribution of values of the property of the given layer.

Abstract: A system and method for providing three dimensional printing production quality prediction is described herein. The system may include logic to scan a region of interest associated with a layer of a plurality of parts during printing to obtain an input for the region of interest and compute an input metric associated with the layer based on the input. In response to an initial set of print jobs, at least a portion of the plurality of parts is mechanically tested to determine at least one output. In response to a production print job, a likelihood of a part of the plurality of parts to satisfy a quality specification is predicted by inputting the input metric to at least one machine learning function comprising the at least one output, wherein the at least one machine learning function is trained during the initial set of print jobs.
