10. A method of compensating for non-functioning nozzles of a print head in a rapid prototyping system that uses a printing process to print successive cross sections of an object being fabricated, said method comprising:
-
at a point on a build material where said non-functioning nozzle is to deposit a drop of ink, firing a second, functioning nozzle to deposit a drop of ink of a color different than would have been deposited by said non-functioning, nozzle;
displacing said print head; and
at a spot, deeper inside a surface of said object being formed, printing a color under said point that compensates for said deposited drop of ink being of a color different than would have been deposited by said non-functioning nozzle. - View Dependent Claims (11, 12)

13. A rapid prototyping system for producing a desired object from electronic data, said system comprising:
-
a fabrication chamber for holding a bed of powdered base material; and
a print head for distributing successive layers of powder in said fabrication chamber and for selectively ejecting binder and differently colored inks into each layer of powder;
wherein said print head varies a color of successive shells that are nested inwardly from a surface of said object within a single layer of powder to produce a desired apparent coloring for said object. - View Dependent Claims (14, 15, 16, 17, 18)

19. A rapid prototyping system for producing a desired object from electronic data, said system comprising:
-
a fabrication chamber for holding a bed of powdered base material; and
a print head for distributing successive layers of powder in said fabrication chamber and for selectively ejecting binder and differently colored inks into each layer of powder, said print head having a plurality of nozzles for ejecting said colored inks;
wherein said print head varies a color of successive shells that are nested inwardly from a surface of said object within a single layer of powder to produce a desired apparent coloring for said object;
wherein said print head, at a point on a layer of said powder where said non-functioning nozzle is to deposit a drop of ink, fires a second, functioning nozzle to deposit a drop of ink of a color different than would have been deposited by said non-functioning, nozzle; and
wherein said print head, at a spot, deeper inside said surface of said object being formed, prints a color under said point that compensates for said deposited drop of ink being of a color different than would have been deposited by said non-functioning nozzle.

20. A system producing a desired apparent coloring in an object produced through rapid prototyping, said system comprising:
-
means for building a series of successive cross sections of said object from a base material to form said object; and
means for varying a color of successive shells that are nested inwardly from a surface of said object within each cross section of said object to produce said desired apparent coloring. - View Dependent Claims (21, 22, 23, 24, 25)
