    Abstract: Printers with orientable micro-mirrors are disclosed. An example printer includes a first micro-minor, a second micro-minor, a third micro-mirror, an energy source; and a controller. The controller is to, during a first time period, orient the first micro-mirror toward a first area of a powder bed, orient the second micro-minor toward the first area of the powder bed, orient the third micro-mirror toward a second area of the powder bed, and activate the energy source, wherein powder in the first area of the powder bed fuses to form a portion of an object in response to energy directed by the first micro-mirror toward the first area and in response to concurrent direction of energy by the second micro-minor toward the first area.

    Abstract: Some examples include a method of producing a three-dimensional object including successively forming a plurality of layers within a print area. The successively forming the plurality of layers within the print area includes depositing a first material including first solid particles, selectively spraying a second material on the first material, the second material including second solid particles suspended in a liquid medium, wherein the first material has a different chemical composition than the second material, and applying fusing energy to the first material and the second material in each of the plurality of layers to form the three-dimensional object including a first region comprised of the first material, a second region comprised of the second material, and a transition region comprised of the first material and the second material extending between the first and second regions.

    Abstract: In one example in accordance with the present disclosure, a printhead cleaning device is described. The printhead cleaning device includes a first spout to generate a first cleaning agent fountain to bathe a printhead die as it traverses over the printhead cleaning device. A pump passes the cleaning agent through the first spout to generate the first cleaning agent fountain. The printhead cleaning device also includes a structure to support the first spout.
