摘要： A system determines an object part density relative to a build region in a layer of build material used in an additive manufacturing machine, the object part density based on a relative portion of the build region where an energy absorbing agent is applied. The system controls a thermal characteristic of the build region in the layer of build material based on the determined object part density.

摘要： In an example, a method includes segmenting, using a processor, a virtual volume comprising a representation of at least a part of an object to be generated in additive manufacturing. The virtual volume may be segmented into a plurality of segments and the object may be intended to have a first color. Additive manufacturing control instructions may be determined for the segments. The additive manufacturing control instructions may comprise instructions for distributing the print agent composition and the additive manufacturing control instructions for each segment may be determined based on the thermal properties of a print agent composition intended to provide the first color to compensate for variations in object dimensions associated with the thermal properties.

摘要： Examples of curl compensation through selective ink usage are described. In an example, whether curling is likely to occur on a printed page may be determined. The page may be printed using a first ink lacking anti-curl properties and a second ink having anti-curl properties in response to determining that curling is likely to occur.

摘要： In an example, a virtual build volume comprising a representation of at least a part of an object to be generated in additive manufacturing is segmented into a plurality of nested segments comprising a core segment, an inner peripheral segment and an outer peripheral segment. Additive manufacturing control instructions may be generated for the nested segments. The control instructions for the core segment may provide a first region of the object corresponding to the core segment and having a first color. The control instructions for the outer peripheral segment may provide a second color for a second region of the object corresponding to the outer peripheral segment. The control instructions for the inner peripheral segment may provide a third color for a third region of the object corresponding to the inner peripheral segment, wherein a color of the third region is determined so as to at least partially visually mask the first region.

摘要： An image file is prepared for printing. The image file is received. The image file includes a cell having pixels. A pixel of the pixels of the cell corresponds with a command to apply a print substance to a medium. For the pixel, the command to apply the print substance is selectively replaced with a command to not apply the print substance.

摘要： Examples of curl compensation through selective ink depletion are described. In an example, whether printing in a region of a page is likely to produce curling of the page may be determined based on a page location and a print density of the region. The region of the page may be printed with a depleted amount of an ink in response to determining that printing the region at the page location with the print density is likely to produce curling of the page.

摘要： In an example, a method includes forming a layer of build material, processing a first portion of the build material by distributing a print agent using a first distribution pattern, the first distribution pattern having a first print agent dispersion characteristic and processing a second portion of the build material by distributing a print agent using a second distribution pattern, the second distribution pattern having a second print agent dispersion characteristic. The method may further include heating the build material by exposing the layer of build material to radiation so as to cause fusing of the first and second portion.
