摘要： 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.

摘要： According to examples, an apparatus includes a processor and a memory on which is stored machine readable instructions. The instructions may cause the processor to identify an intended surface property level for a surface of a three-dimensional (3D) object, determine an amount of radiation to be applied as a flash of radiation onto the surface to obtain the intended surface property level, and output the determined amount of radiation to be applied as a flash of radiation, in which a radiation source is to flash apply the determined amount of radiation onto the surface of the 3D object.

摘要： According to examples, an apparatus may include a build platform and a chamber. The chamber may support a layer forming station including a spreading component to spread a layer of build material particles onto the build platform and an agent delivery component to apply fusing agent onto selected locations on the spread layer of build material particles and a heating station including a heating component to apply energy onto the spread layer of build material particles and the applied fusing agent, in which the heating station is separated from the layer forming station. The apparatus may also include an actuator to move the chamber with respect to the build platform or vice versa while maintaining the separation between the layer forming station and the heating station.

摘要： An additive manufacturing method includes: selecting one of a plurality of irradiation modules based on a selected module having a wavelength band tuned for absorption by a fusing agent to be used to form an object by additive manufacture; plugging the selected module into a socket over the build platform; supporting successive, stacked layers of the object being formed on the build platform; using a liquid dispenser mounted on the carriage, selectively dispensing the fusing agent into an uppermost layer of build material in a pattern corresponding to a layer of the object being formed; and fusing the build material by exposing the fusing agent to a first wavelength band from a first irradiation source in the selected module.

摘要： According to an example, an apparatus may include a processor and a memory on which is stored instructions. The instructions may cause the processor to control at least one energy source to apply energy at a certain low energy level onto a layer of metallic particles, in which the metallic particles have micron-level dimensions, and in which application of the certain low energy level may sinter the metallic particles and may cause formation of physical connections between adjacent ones of the metallic particles. The instructions may also cause the processor to control the at least one energy source to apply energy at a certain high energy level onto the layer of metallic particles, in which application of the certain high energy level energy may melt and fuse the sintered metallic particles.

摘要： The present disclosure is drawn to coalescent inks and material sets, such as for 3D printing. In one example, the coalescent ink can include a conjugated polymer, a colorant imparting a visible color to the coalescent ink, and an ink vehicle comprising a high boiling point co-solvent having a boiling point of 250° C. or greater. The high boiling point co-solvent can be present in an amount from about 1 wt % to about 4 wt % with respect to the coalescent ink.

摘要： In an example of a method for forming three-dimensional (3D) printed electronics, a build material is applied. A fusing agent is selectively applied on at least a portion of the build material. The build material is exposed to radiation and the portion of the build material in contact with the fusing agent fuses to form a layer. An electronic agent is selectively applied on at least a portion of the layer, which imparts an electronic property to the at least the portion of the layer.
