Abstract

In an example of the disclosure, a priming lane and a non-priming lane are identified within an image frame to be printed by a printer. A line of molten wax is applied to the roller. The molten wax when cooled is to form a wax ridge upon the roller. The roller having the formed wax ridge is wetted with the primer. The wetted roller is rotated against the substrate to apply the primer. A first width of the wetted roller that does not include the wax ridge forms the priming lane upon the substrate. A second width of the roller that includes the wax ridge causes the primer to not transfer and thereby forms the non-priming lane upon the substrate.

Abstract

According to examples, machine-readable instructions in a computerreadable medium may cause a processor to access a digital model of a 3D object including a lattice structure formed of structural elements. The processor may also generate a 2D map of a surface of the digital model, calculate locations at which the structural elements in the lattice structure intersect with the 2D map of the surface, generate a 2D image including the calculated locations and a perimeter of the 2D map of the surface, and generate a pattern onto the 2D image, in which the generated pattern connects and covers a plurality of the calculated locations. The processor may further convert the 2D image with the generated pattern into a 3D surface of the digital model and modify the digital model of the 3D object to include the generated pattern.

Abstract

An example electronic device includes a display device, and a sensor to detect position data of a user of the electronic device. The position data indicates a position and orientation of the user relative to the display device. In addition, the electronic device includes a controller coupled to the sensor and the display device. The controller is to: receive the position data from the sensor; use a machine learning model and the position data to classify an interaction of the user with the electronic device in a first ergonomic category or a second ergonomic category; and adjust an angular position of a display device or an output from the display device responsive to a classification of the interaction in the first ergonomic category.

Abstract

An image acquisition device may include a processor and a memory including a shadow correction module. The shadow correction module may receive an input image having a shadow and convert the input image into a grayscale image. Further, the shadow correction module may determine a foreground element on the grayscale image having a maximum height. Furthermore, the shadow correction module may generate the shadow map by performing a morphological closing operation on the grayscale image using a structural element having a dimension corresponding to the maximum height. Further, the shadow correction module may generate an output image by compensating for the shadow in the input image using the shadow map.

Abstract

An example system includes a plurality of energy emitters to deliver energy to a material bed to fuse build material at a plurality of locations receiving the energy. The system also includes a controller to a controller to determine an amount of energy to deliver to each location to achieve a fusing condition based on data indicating the plurality of locations to be fused and based on predicted thermal transfer between the plurality of locations receiving the energy. The controller also is to cause the plurality of energy emitters to deliver the determined amount of energy to each location of the material bed.

An expected fulfillment time period is subtracted from the predicted number of days to determine a number of days until a fulfillment event occurs. A threshold remaining life of the consumable item is correlated with the number of days until the fulfillment event occurs. That the remaining life of the consumable item has reached the threshold remaining life is detected, and fulfillment of a replacement consumable item to replace the consumable item is responsively initiated.
