Examples of methods for object manufacturing visualization by an electronic device are described herein. In some examples, a predicted thermal image of additive manufacturing is determined using a machine learning model. In some examples, a captured thermal image is obtained. In some examples, a graphical overlay of the predicted thermal image with the captured thermal image is presented.

Object manufacturing visualization

According to examples, an apparatus may include a processor and a memory on which is stored machine readable instructions that when executed by the processor are to cause the processor to access a reduced resolution three-dimensional (3D) model file of an object to be built in a build bed of a 3D printing system, the reduced resolution 3D model file comprising a reduced resolution file of a first resolution 3D model file of the object. The instructions may also cause the processor to determine a packing arrangement for the object and a plurality of other objects to be built in the build bed through use of the reduced resolution 3D model file and output the determined packing arrangement for the 3D printing system to print the object and the other objects.

Packing arrangement determination for 3D printing of objects

An example of a non-transitory computer-readable medium storing machine-readable instructions. The instructions may cause the processor to receive a three-dimensional (3D) object representation and subdivide it into a triangular grid. Curved triangles may be calculated for triangles in the triangular grid. The triangles may be subdivided and differences calculated between corresponding sections of the curved triangles and the received 3D object representation.

Determination of vertices of triangular grids for three-dimensional object representations

An image processing system acquires a first three-dimensional model of an object. The image processing system includes a processor and storage medium encoded with instructions executable by the processor. The instructions include instructions to define a material potential function for a material. The material potential function is a function of a three-dimensional origin point of the material in the object, a three-dimensional propagation limit of the material in the object, and a three-dimensional propagation function of the material in the object. The instructions include instructions to generate a second three-dimensional model of the object based in part on the material potential function and the first model. The second model illustrates propagation of the material through an interior volume of the object at a unit level. A controller generates control signals based on the second model, and a fluid ejection engine performs an additive manufacturing process based on the control signals.

Propagation of a material through an interior volume of a three-dimensional object

A method of manufacturing an object via three-dimensional printing is disclosed. Data regarding the object is received. The object is three-dimensionally printed from the data. A wrapper is also three-dimensionally printed from the data. The wrapper encloses the object and includes information regarding the object.

Three-dimensionally printed object

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.

3D object parts and cage fabrication

An example of a computer-readable medium is provided to store machine-readable instructions. The instructions may cause a processor to receive three-dimensional (3D) object representations of an object. The distance between points of a grid applied to 3D object representation and random points on the 3D object representation may provide a sampling error used in calculating a modeling accuracy between the 3D object representations.

Determination of modeling accuracy between three-dimensional object representations

In one implementation, a method for generation of a soft-proof file is described. A ticket template and a job definition are associated with input contents. Print-ready data is caused to be generated based on the input content, the job definition, and the ticket template. A soft-proof file is caused to be generated based on the print-ready data, the ticket template, and the job definition.

Soft-proof file generation based on print-ready data

In example implementations, a plurality of re-structured version of texts is generated for each one of a plurality of different documents by applying a plurality of text summarization methods to each one of the plurality of different documents. An effectiveness score is calculated for each one of the plurality of text summarization methods to determine the text summarization method with the highest effectiveness score for an application. The plurality of re-structured versions of text for each one of the plurality of different documents that is generated by the text summarization method that has the highest effectiveness score is stored to be used in the application.

Text restructuring

Examples herein disclose multiple engines to produce output representative of a summary of document produced by each of the multiple engines. The examples apply a weighting mechanism to the output specific to that engine to obtain a value corresponding to that output. The examples identify specialized language if the value corresponding to that output reaches at least a particular threshold.

Specialized language identification

A technique for displaying a folding document can include connecting an edge of a first panel to an edge of a second panel to create a shared edge representing a fold of a folding document. The first panel and second panel can form a first area of the folding document, and the first area and a second area of the folding document can be displayed in a graphical user interface (GUI).

Displaying a folding document

Techniques pertaining to embedding fonts in a PDF document are disclosed. A processing component executing a PDF application programming interface (API) may be operative to identify each character in a PDF file associated with an un-embedded font. The PDF API may store a bitmap representation for each identified character in the PDF file associated with the un-embedded font. The PDF API may then create a bitmap font character from the bitmap representation for each identified character in the PDF file associated with an un-embedded font and replace each reference to a character in the PDF file associated with an un-embedded font with a reference to its corresponding bitmap font character.
