Abstract:
A method of making a bas relief from a two-dimensional image includes converting a two-dimensional image to a gray-scale image that comprises a plurality of shades of gray. Each shade of gray corresponds to a respective elevation of a three dimensional representation of the two-dimensional image. The gray-scale image is then converted to a half-tone bitmap image that is etched onto a print screen stencil. Meltable powder is forced through the open mesh areas of the print screen stencil to form a three-dimensional pattern of powder on a substrate positioned beneath the print screen stencil in spaced-apart relationship therewith. The three-dimensional pattern of the powder corresponds to the three-dimensional representation of the two-dimensional image. The three-dimensional pattern of powder is then heated to fuse the powder together to form a bas relief.
