Abstract: 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.

Abstract: A polymeric powder composition for three-dimensional printing includes first, second, and third polymeric particles. The first particles, having a first average size, are present in an amount ranging from about 70 wt % to about 95 wt %. The second particles, having a second average size smaller than the first average size, are present in an amount ranging from about 0.5 wt % to about 21 wt %. The third particles, having a third average size smaller than the second average size, are present in an amount ranging from greater than 0 wt % up to about 21 wt %. Each of the first, second, and third average sizes independently ranges from 5 μm to about 100 μm. A sum of the fractional weight ratios of all of the polymeric particles in the polymeric powder composition equals

Abstract: 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.
