    Abstract: In an example, a method includes receiving, at least one processor, object model data representing at least a portion of a first object that is to be generated by an additive manufacturing apparatus by fusing build material within a fabrication chamber. An indication of an amount of fused build material in a region of the fabrication chamber which is to be below the region in which the first object is to be generated may be determined and a dimensional compensation value to apply to the object model data representing the first object may be determined based on the determined indication. The determined dimensional compensation value may be applied to the object model data to derive modified object model data.

    Abstract: A color camera system according to an example includes a red, green, blue (RGB) color camera device to capture images of an object, and a polarized illumination source to illuminate the object during the capture of the images. The color camera system further includes a liquid crystal tunable polarization filter positioned between the camera device and the object, wherein the liquid crystal tunable polarization filter is to provide the camera device with selectable linear polarization viewing states for capturing the images of the object, and is to provide capability for each RGB pixel to be uniquely processed using RGB color distinct polarization filter parameters.

    CPC classification number: B41J2/1652

    Abstract: It is hereby disclosed a method to print on porous substrate by a printer comprising: a print zone; a conveyor to receive a porous substrate on a loading zone and to move the porous substrate along a transport direction between the print zone and the loading zone; a print engine positioned on the print zone for ejecting printing fluid towards the porous substrate; wherein the method comprises ejecting printing fluid towards a front side the porous substrate and, by a controller, activating a vacuum source as to exert a vacuum on a back side of the porous substrate being the vacuum exerted while the porous substrate is within the print zone.

    Abstract: In some examples, a system receives a representation of a lattice cell and information representing a target modified behavior of the lattice cell. The representation of the lattice cell including an arrangement of beams of the lattice cell. The system generates a modified lattice cell based on the representation of the lattice cell and the information, where the modified lattice cell includes the arrangement of the beams and an added behavior adjustment structure that is connected to a selected beam of the arrangement of the beams.
