Abstract
The present invention is a three dimensionally printed sharpening tool with diamond abrasive and method of making. The diamond-polymer resin composite tool is shapeable and personalizeable with printed imbedded logos for brand specific manufacturing which co-function as embedded dimension specific markers in multiple layers enabling a single tool to provide sharpening, lapping and polishing in a single operation.
Claims10
A three dimensionally printed sharpening tool comprising:
- a first layer formed of a first plurality of filaments, each of the first plurality of filaments having a vertically facing surface and an horizontally facing surface, at least a portion of the horizontally facing surfaces of each of the first plurality of filaments abutting against, and at least partially merging with, at least a portion of the horizontally facing surfaces of at least one other of the first plurality of filaments;
- and
- a second layer formed of a second plurality of filaments, each of the second plurality of filaments having a vertically facing surface and an horizontally facing surface, at least a portion of the horizontally facing surfaces of each of the second plurality of filaments abutting against, and at least partially merging with, at least a portion of the horizontally facing surfaces of at least one other of the second plurality of filaments;
- wherein at least a portion of the vertically facing surfaces of each of the first plurality of filaments abutting against, and at least partially merging with, at least a portion of the vertically facing surfaces of at least one of the second plurality of filaments;
- and
- wherein the first plurality of filaments formed of a composite mixture of at least one of poly-lactic acid and thermoplastic elastomer, with at least one of an abrasive component, the abrasive component being chosen from the group consisting of diamond, cubic boron nitride, zirconia, aluminum oxide, sapphire, silicon carbide, and garnet.

A method of three-dimensionally printing a sharpening tool comprising:
- extruding an abrasive ink with at least one of an abrasive component, the abrasive component being chosen from the group consisting of diamond, cubic boron nitride, zirconia, aluminum oxide, sapphire, silicon carbide, and garnet;
- forming a first layer of a first plurality of filaments with the extruded abrasive ink, each of the first plurality of filaments having a vertically facing surface and an horizontally facing surface, at least a portion of the horizontally facing surfaces of each of the first plurality of filaments abutting against, and at least partially merging with, at least a portion of the horizontally facing surfaces of at least one other of the first plurality of filaments;
- and
- laying down a second layer formed of a second plurality of filaments, each of the second plurality of filaments having a vertically facing surface and an horizontally facing surface, at least a portion of the horizontally facing surfaces of each of the second plurality of filaments abutting against, and at least partially merging with, at least a portion of the horizontally facing surfaces of at least one other of the second plurality of filaments;
- and
- wherein at least a portion of the vertically facing surfaces of each of the first plurality of filaments abutting against, and at least partially merging with, at least a portion of the vertically facing surfaces of at least one of the second plurality of filaments.
