Monochromatic or multichromatic images may be created on surfaces. The surface is moved to first, second and third stations. The surface is electrically biased, and powder is transferred to the surface electrostatically at the first station. The powder is fused or sintered selectively on the surface at the second station. Unfused or unsintered portions of the powder are removed from the surface at the third station.
