Abstract
This disclosure relates to a method of 3-D printing comprising: applying a layer of build material onto a print platform, wherein the build material comprises particles of a polymer comprising polymer chains having at least one reactive group that is protected with a protecting group; printing a de-protecting agent at selected locations on the layer of build material; and coalescing particles of the polymer at the printed locations on the layer of build material to form a coalesced polymer layer.
