Abstract

An electronic file containing height field mapping data is output to a specialized printer and used to create one or more three dimensional molds. The molds, in turn, may be used to fabricate bas-relief tiles and similar three-dimensional objects from various materials. The process allows for rapid deployment of customized design elements in many construction applications and environments.

Claims

1. A method comprising the steps of:

loading a digital image file into a computer memory;

converting said digital image file into a bitmap file;

processing said bitmap file to create a heightfield map;

using the heightfield map to create a 3D model;

creating a mold based on said 3D model in said computer memory, wherein said step of processing said bitmap file into said heightfield map comprises creating a polygon mesh to describe said heightfield map as a set of connected triangles; and

creating at least two different tiles that can be manufactured from said mold, wherein the at least two different tiles include ceramic, glass tiles, gypsum polymer tiles and plastic resin tiles.

2. The method of claim 1 wherein said step of loading a digital image file into said computer memory comprises the step of loading a jpeg file from a digital camera or scanner into said computer memory.

3. The method of claim 1 wherein said step of loading a digital image file into said computer memory comprises the step of downloading an electronic file from the Internet into said computer memory.

4. The method of claim 1 wherein a three-dimensional printer, Computer Numeric Controlled (CNC) milling or stereo lithography is used to create the physical object.

5. The method of claim 1 wherein said mold comprises a rubber, plaster or metal mold.

6. The method of claim 1 further comprising the steps of:

mixing metal powder with a gypsum polymer material or plastic resin; and

applying said gypsum powder or said plastic resin to said mold.

7. The method of claim 6 wherein said metal powder comprises one of a brass powder, a bronze powder and a nickel/silver powder.

8. An apparatus comprising:

a network

a computer coupled to said network, said computer comprising a memory to implement the steps of;

loading a digital image file into a computer memory;

converting said digital image file into a bitmap file;

processing said bitmap file to create a heightfield map;

using the heightfield map to create a 3D model;

creating a mold based on said 3D model in said computer memory, wherein said step of processing said bitmap file into said heightfield map comprises creating a polygon mesh to describe said heightfield map as a set of connected triangles; and

creating at least two different tiles that can be manufactured from said mold, wherein the at least two different tiles include ceramic, glass tiles, gypsum polymer tiles and plastic resin tiles.
