Abstract

A device, method and layered product produced from the method are disclosed. The method uses new fabrication steps involving stratified additive manufacturing. Steps include preparing continuous ribbons of solid first material and possibly a second material; rolling continuous ribbon onto a spool held within a feeder cassette configured to dispense continuous ribbon through a slit; loading each feeder cassette onto an engagement dock; dispensing on the bed of the machine a first strip of continuous ribbon; cutting it to a length and having an end profile as directed by digital specification programmed on the machine; and creating a layered object by dispensing, cutting and applying additional strips of continuous ribbon atop the previously dispensed strips in accordance with the digital specification. The apparatus includes a computer numerical control machine feeding strips of ribbon from the feeder cassettes loaded in an engagement dock.

Claims (19)

1. A method of producing a product using stratified additive manufacturing, the method comprising the steps of:

preparing a plurality of continuous ribbons of first material, said first material having a solid state, the plurality of continuous ribbons comprising a plurality of different widths;

wherein each continuous ribbon comprises a top surface and a bottom surface; and further comprising the step of attaching a radio-frequency identification tag to the bottom surface;

rolling each continuous ribbon in the plurality of continuous ribbons onto a spool held within a feeder cassette so that each feeder cassette holds one roll of continuous ribbon and so that there are a plurality of feeder cassettes, each feeder cassette configured to dispense continuous ribbon through a slit in said feeder cassette;

loading each feeder cassette in the plurality of feeder cassettes onto an engagement dock of a computer numerical control machine;

dispensing above the computer numerical control machine a first portion of continuous ribbon from a first feeder cassette in the plurality of feeder cassettes while preserving the solid state of the first portion;

cutting the first portion to a length and having an end profile as directed by digital specification programmed on the computer numerical control machine; and

creating a layered object by dispensing, cutting and applying additional portions of continuous ribbon from one or more feeder cassettes in the plurality of feeder cassettes where each of the additional portions has a butt joint with a previously dispensed portion or is added atop the previously dispensed portion in accordance with the digital specification programmed on the computer numerical control machine.

2. The method of claim 1 , wherein the additional portions of continuous ribbon are dispensed so that any butt joint is covered by a next layer applied atop the butt joint so as to form a woven connectivity.

3. The method of claim 1 , further comprising the step of selecting the first material from the group consisting of wood veneer, metal, plastic, cork, leather, fabric, fiber and any combination of these.

4. The method of claim 1 , wherein each continuous ribbon comprises a top surface and a bottom surface; and further comprising the step of adding an adhesive to said bottom surface.

5. The method of claim 1 , further comprising the step of spraying at least one continuous ribbon in the plurality of continuous ribbons with particles, said particles selected from the group consisting of an electrical conductor, an electrical insulator, a paint, a dye and a pigment, a chemically reactive agent; and a penetrant.

6. The method of claim 1 , further comprising the step of milling the layered object prior to completing actions of dispensing, cutting and applying additional portions of continuous ribbon.

7. The method of claim 1 , further comprising the step of:

preparing a continuous ribbon of second material, said second material having a solid state, the second material being different from the first material;

rolling the continuous ribbon of second material onto the spool held within a second feeder cassette so that the second feeder cassette holds one roll of continuous ribbon of second material;

loading the second feeder cassette holding the continuous ribbon of second material onto the engagement dock of the computer numerical control machine;

dispensing onto a previously dispensed portion a measured length of such continuous ribbon of second material through the slit in said second feeder cassette while preserving the solid state of the second material; and

cutting the measured length to the end profile directed by digital specification programmed on the computer numerical control machine.
