Abstract

A method of laminated object additive manufacturing for veneer applications may include, but is not limited to, loading at least one veneer into a laminated object additive manufacturing device, feeding a first layer of the at least one veneer over a working surface of the laminated object additive manufacturing device, cutting the first layer of the at least one veneer to form a first portion of the veneer product, actuating the working surface, feeding an additional layer of the at least one veneer over the first layer of the at least one veneer, and cutting the additional layer of the at least one veneer to form an additional portion of the veneer product. The at least one veneer may be fabricated from a mixture including wood product and a binder. The first layer and/or the additional layer may be cured.

First claim

What is claimed:

1. A method of laminated object additive manufacturing for veneer applications, comprising:
loading at least one veneer into a laminated object additive manufacturing device, the at least one veneer being fabricated from a mixture including wood product and a binder;
feeding a first layer of the at least one veneer over a working surface of the laminated object additive manufacturing device;
cutting the first layer of the at least one veneer to form a first portion of a veneer product;
laminating the first layer;
actuating the working surface;
feeding an additional layer of the at least one veneer over the first layer of the at least one veneer;
cutting the additional layer of the at least one veneer to form an additional portion of the veneer product;
adjusting one or more operational parameters of the laminated object additive manufacturing device via a controller;
forming at least one of a veneer block or a veneer log;
slicing the at least one of the veneer block or the veneer log, wherein slicing the at least one of the veneer block or the veneer log generates a secondary veneer; and
loading the secondary veneer into the laminated object additive manufacturing device.

2. The method of claim 1 , further comprising:
curing the first layer to form the first portion of the veneer product.

3. The method of claim 1 , further comprising:
curing the first layer and the additional layer to form the additional portion of the veneer product.

4. The method of claim 1 , the at least one veneer including a plurality of veneers, the method further comprising:
feeding a first layer of each of the plurality of veneers over the working surface of the laminated object additive manufacturing device;
cutting the first layer of each of the plurality of veneers to form a portion of the veneer product;
laminating the first layer;
actuating the working surface;
feeding an additional layer of each of the plurality of veneers over a first set of layers of the plurality of veneers; and
cutting the additional layer of each of the plurality of veneers to form the additional portion of the veneer product.

5. The method of claim 4 , further comprising:
curing the first layer of each of the plurality of veneers to form the first portion of the veneer product.

6. The method of claim 4 , further comprising:
curing the first layer of each of the plurality of veneers and the additional layer of each of the plurality of veneers to form the additional portion of the veneer product.

7. The method of claim 1 , the at least one veneer including at least one roll of veneer.

8. The method of claim 1 , the binder being a thermoplastic.

9. The method of claim 1 , the binder being an adhesive.

10. The method of claim 1 , the mixture further including at least one of a fire-retardant or a fire-resistant material.

11. The method of claim 10 , the mixture further including a metal.

12. A method of laminated object additive manufacturing for veneer applications, comprising:
loading at least one veneer into a laminated object additive manufacturing device, the at least one veneer being fabricated from wood product and a binder, the at least one veneer loaded into a feed tray of the laminated object additive manufacturing device;
laminating the at least one veneer;
stacking the at least one veneer within a curing tray of the laminated object additive manufacturing device;
curing the at least one veneer to form at least a portion of a veneer product; and
adjusting one or more operational parameters of the laminated object additive manufacturing devices via a controller;
forming at least one of a veneer block or a veneer log;
slicing the at least one of the veneer block or the veneer log, wherein slicing the at least one of the veneer block or the veneer log generates a secondary veneer; and
loading the secondary veneer into the laminated object additive manufacturing device.

13. The method of claim 12 , the at least one veneer including a plurality of sheets of veneer.

14. The method of claim 12 , the at least one veneer including a plurality of veneer log slices.

15. The method of claim 1 , wherein the wood product includes at least one of wood chips or wood powder, wherein the binder includes an adhesive configured as an epoxy resin.

16. The method of claim 12 , further comprising:
applying an additional binder to the at least one veneer while the at least one veneer passes from the feed tray to the curing tray.
