▎ 摘　　要

NOVELTY - The method involves providing an amount of a material that comprises elongate elements (16) over portion of the selected surface portion of a layer (6) of particulate material. The radiation (8) is provided across the selected surface portion of the layer of particulate material so as to sinter a portion of the material of the layer including causing multiple elongate elements to become embedded in the sintered portion of material. The elongate elements are selected from the group of elongate elements consisting of carbon nanotubes and elongate graphene plates. USE - Method for selectively sintering particulate material. ADVANTAGE - The carbon nanotubes are embedded within the produced object so to provide that the object has improved structural stiffness. Since the carbon nanotubes are aligned along meandering paths through the formed object, the improved electrical conductivity along such paths are provided. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a three dimensional object; and (2) an apparatus for selectively sintering particulate material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating the apparatus for combining particulate material.
