Abstract: A coating system includes a leveling element and a dispenser assembly. The leveling element extends generally transverse to a substrate advance orientation and is releasably engageable against a substrate support. The dispenser assembly includes an array of side-by-side independent liquid dispensers and an air pressure assembly to supply a common air pressure to each dispenser to cause pressurized dispensing of a coating liquid from each dispenser onto a substrate on the substrate support. The liquid dispensing occurs at least during relative movement between the dispenser assembly and the substrate support and during the relative movement, the leveling element is actuated to uniformize the coating liquid on the substrate.

Abstract: Described herein are methods and systems for printing a three-dimensional object. In an example, a method for printing a three-dimensional object can comprise: (i) a metallic build material being applied; (ii) a binder fluid being applied on at least a portion of the metallic build material; (iii) the selectively applied binder fluid can be flash fused to bind the metallic build material and the selectively applied binder fluid by application of an energy flux having an energy density of from about 0.5 J/cm2 to about 20 J/cm2 for less than about 1 second. In the example, (i), (ii), and (iii) can be repeated at least one time to form the three-dimensional object. The binder fluid can comprise a liquid vehicle and polymer particles dispersed in the liquid vehicle.

Abstract: According to an example, a three-dimensional (3D) printer may include a delivery device to deposit a light absorbing agent onto selected areas of a layer of build material particles, in which the light absorbing agent absorbs light having wavelengths that are around the ultraviolet wavelength range. The 3D printer may also include a light source to apply light onto the selectively deposited light absorbing agent and the layer of the build material particles, in which the light absorbing agent absorbs light around the ultraviolet wavelength range from the applied light and becomes heated to a temperature that causes the build material particles upon which the light absorbing agent has been deposited to melt and to fuse together following cessation of the application of the light.
