Embodiment Construction

[0014] The present invention includes techniques for adding a full spectrum of shades of color, as well as a wide range of saturation and brightness, to objects produced by a rapid prototyping system, preferably using printing techniques. The present invention recognizes that, depending on the transparency of the material from which the article is made, color is produced by reflection from and absorption by the colorant at or below the surface of the article. The present invention also recognizes that the apparent color can be fine tuned by nesting layers of different colors near the surface of the shaped article.

[0015] As used throughout the specification and appended claims, the term "apparent color" refers to the color of an item as it appears to an observer. In accordance with the principles of the present invention, the colorant that contributes to the "apparent color" may be located on the actual surface of the object or within the object rather than on the surface of...

Abstract

A method of producing a desired apparent coloring in an object (200) produced through rapid prototyping includes varying a color of successive layers (201,202,203,204) that are nested inwardly from a surface of the object (200).

Description

technical field [0001] The present invention relates to rapid prototyping, and more particularly to the coloring of objects resulting from rapid prototyping. Background technique [0002] Rapid prototyping is rapidly becoming a popular method for preparing three-dimensional objects including prototype components and working tools. Rapid prototyping is a method in which objects described by electronic data are constructed automatically from base materials. The principles of rapid prototyping include printing. [0003] When printing is used in rapid prototyping, multiple printed planar layers are combined to form non-planar three-dimensional objects. Components are prepared by printing or spraying a binder on a powder slab, where the powder solidifies into a cross-section of the shaped object; by printing layer after layer, each layer representing the final intended product Another cross-section, adjacent printing layers are bonded to each other in a predetermined way to fo...
