Abstract
A detector for measuring a thickness of a powder on a surface includes a body; a device extending from the body for facilitating holding the body on the surface; and a plurality of teeth extending from the body and spaced from each other along the plane, each of the teeth being defined by two walls extending from the body so as to form a distinct line of intersection extending perpendicular to the plane at a point remote from the body, each of the teeth being of a different length. A method of detecting a thickness of a layer of powder on a surface includes the steps of placing the detector on the surface such that the detector extends substantially perpendicularly to the surface; sliding the detector along the surface in a direction that is perpendicular to the plane of the body for a distance that is greater than a thickness of the body; examining the layer of powder on the surface in a location over which the detector was slid; identifying which, if any, of the teeth made an imprint in the powder; and determining the thickness of the layer by the unique distance of the teeth that made an imprint in the powder.
