Abstract: According to examples, a computer-readable medium may have stored thereon instructions that may cause a processor to obtain a first 3D model of a first portion of a component, the first 3D model may include a first digital attachment edge corresponding to a first attachment edge on the first portion. The processor may obtain a second 3D model of a second portion of the component, the second 3D model may include a second digital attachment edge corresponding to a second attachment edge on the second portion, in which the second portion is to be joined with the first portion to form the component. The processor may modify the first 3D model to include a first digital rib including holes along a segment of the first digital attachment edge and the second 3D model to include a second digital rib including protrusions along a segment of the second attachment edge.

Abstract: Example implementations provide a sealing assembly to a seal an aperture, coupling two chambers, the aperture being arranged to accommodate a printhead carriage; the assembly comprising: at least one curtain capable of being disposed in a sealing relationship with the aperture; the at least one curtain being capable of being positioned either side of the printhead carriage, and at least one biasing arrangement to bias the at least one curtain into a biased state; the biased state comprising a component orthogonal to a longitudinal length of the at least one curtain.

Abstract: According to examples, a non-transitory computer-readable medium may have stored thereon instructions that may cause a processor to obtain a three-dimensional (3D) model of a component to be fabricated by a 3D fabrication system, the 3D fabrication system having a build volume. The processor may also determine, based on a set of factors, a partitioning of the 3D model into separate sections, in which the separate sections may correspond to portions of the component that are sized to be fabricated within the build volume. The processor may further modify the 3D model to model the component as the separate sections.

Abstract: A printer comprises a print head comprising nozzles to selectively deposit liquid drops to selected portions of a receiving surface, a radiation light source to supply first light to the receiving surface, and a drop detector. The drop detector detects a flying liquid drop ejected by one of the nozzles and comprises a detector light source to emit a light beam of second light and a light detector to detect the light beam of the second light. The second light is distinguishable by the drop detector from the first light.

Abstract: Examples relate to a 3D printer capable of positioning a printhead relative to a spittoon disposed within a maintenance region of the 3D printer, ejecting printing fluid from the printhead onto the spittoon, and positioning a moveable heat source proximate to the spittoon to evaporate printing fluid from the spittoon.
