Abstract
A method of producing a complex product includes designing a three dimensional preform of the complex product, creating a three dimensional preform of the complex product using the model, depositing a material on the preform, and removing the preform to complete the complex product. In one embodiment the system provides a complex heat sink that can be used in heat dissipation in power electronics, light emitting diodes, and microchips.
Claims6
A method of producing a complex product, the method comprising the steps of:
- designing a three dimensional preform of the complex product to form a model preform by computer aided design software at using a PC controller producing a computer aided design (CAD) model of said model preform,
- electronically slicing said computer aided design (CAD) model into data files producing a digital image of said model preform,
- providing a photoresist/photo-curable composition,
- creating a three dimensional preform of the complex product using said model preform by projecting said digital image of said model preform into said photoresist/photo-curable composition,
- depositing diamond nanoparticles on said created three dimensional preform by electrophoretic deposition,
- depositing copper nanoparticles on said created three dimensional preform by electroplating, and
- removing the created three dimensional preform producing the complex product from the deposited diamond nanoparticles material and deposited copper nanoparticles material.
