  • Publication number: 20220009172
    Abstract: An example of an apparatus is provided. The apparatus includes an input device to receive design data. The design data includes information about a geometry and load characteristics of an object. The apparatus further includes a structural design engine to generate print data to print the object on a three-dimensional printer based on the design data. The apparatus also includes a fluid design engine to generate fluidic data. The fluidic data represents a fluid channel within the object.

  • Publication number: 20220012952
    Abstract: An example device includes: a memory storing instructions; and a processor connected to the memory. The instructions are to cause the processor to: receive predetermined locations of a fluidic input location and fluidic output locations at a three-dimensional (3D) object model; generate respective paths between the fluidic input and each of the fluidic outputs via associated portions of the 3D object model; replace the respective paths with respective hollow connectors that have respective fluidic resistance selected such that each of the fluidic outputs have a predetermined flow rate from the fluidic input to the fluid outputs; and store, at the memory, data indicative of locations and dimensions of the respective hollow connectors, relative to the fluidic input and the fluidic outputs, the data for use by a three-dimensional printer to print a part that includes the fluidic input, the fluidic outputs and the respective hollow connectors.

  • Publication number: 20210402702
    Abstract: In an example, a method includes operating, by a processor, on object model data. The object model data describes at least part of an object to be generated in additive manufacturing. The method also includes determining, by a processor, pattern data. The pattern data comprising areas of variable reflectance intended to be formed on a portion of the object. The method includes determining, by a processor, object generation instructions to apply a fusing agent to at least part of a layer of build material corresponding to the portion of the object in a density corresponding to the reflectance of the generated pattern data.

  • Publication number: 20210162659
    Abstract: A method of packing a three-dimensional (3D) build bed includes, with a shape-based packing module, and for a number of iterations, selecting two parts from a plurality of parts within a parts list, and minimizing a volume of a composite bounding box that encloses both parts. The method may also include determining abounding box reduction ratio (BBRR) by computing the volume of the composite bounding box divided by a sum of the volumes of a first bounding box enclosing a first part of the two parts and a second bonding box enclosing a second part of the two parts, and, in response to a determination that the BBRR is lower than a threshold value, combining the two parts to form a composite part.

  • Patent number: 10471726
    Abstract: In an example, a retainer may comprise a latch to removably engage with a cartridge, an actuator plate to operably engage with the cartridge, a bias member, and a linkage. The actuator plate may operably engage with the cartridge such that, upon engagement with the cartridge, the transmission of signals can occur between the actuator plate and the cartridge. The linkage may be engaged with the actuator plate, the bias member, and the latch, such that linkage causes the actuator plate to be pushed against the cartridge upon the latch being engaged with the cartridge in a locked position.

  • Patent number: 9931854
    Abstract: A disclosed example apparatus to install a pen in an imaging device includes a first guide on a first component of the imaging device to guide the pen in a first direction toward a second component of the imaging device during installation of the pen in the imaging device. The example apparatus also includes a second guide on the second component to receive the pen from the first guide during the installation of the pen. The first guide and the second guide define a gap therebetween and at least one of the first and second guides causes the pen to pass the gap without catching. The second guide is to guide the pen into an installed position in the second component.
