Abstract

A method of binder jetting additive manufacturing for veneer applications may include, but is not limited to, loading a mixture of material into one or more feed boxes of a binder jetting additive manufacturing device, depositing a layer of the mixture of material into a working chamber of the binder jetting additive manufacturing device, applying a coating to the layer of the mixture of material, and curing the coating applied to the layer of the mixture of material to form a portion of a veneer product, actuating a working surface of the working chamber, depositing an additional layer of the mixture of material into the working chamber, applying an additional coating to the additional layer of the mixture of material, and curing the additional coating applied to the additional layer of the mixture of material to form an additional portion of the veneer product.

First claim

What is claimed:

1 . A method of binder jetting additive manufacturing for veneer applications, comprising:
loading a mixture of material into one or more feed boxes of a binder jetting additive manufacturing device, the mixture of material including wood product; depositing a layer of the mixture of material into a working chamber of the binder jetting additive manufacturing device; applying a coating to the layer of the mixture of material; and curing the coating applied to the layer of the mixture of material to form a portion of a veneer product.

2 . The method of claim 1 , the veneer product including a sheet of veneer formed from the layer of the mixture of material.

3 . The method of claim 1 , further comprising:
actuating a working surface of the working chamber; and depositing an additional layer of the mixture of material into the working chamber of the binder jetting additive manufacturing device to form an additional portion of the veneer product.

4 . The method of claim 3 , the veneer product including a veneer block at least formed from the layer of the mixture of material and the additional layer of the mixture of material, the veneer block being at least one of compressed or heated within the binder jetting additive manufacturing device.

5 . The method of claim 3 , the veneer product including a three-dimensional veneer structure at least formed from the layer of the mixture of material and the additional layer of the mixture of material.

6 . The method of claim 3 , further comprising:
applying an additional coating to the additional layer of the mixture of material; and curing the additional coating applied to the additional layer of the mixture of material to form the additional portion of the veneer product.

7 . The method of claim 6 , at least one of the coating or the mixture of material including a binder.

8 . The method of claim 7 , the binder including a thermoplastic.

9 . The method of claim 7 , the binder including an adhesive.

10 . The method of claim 1 , at least one of the coating or the mixture of material including a coating selected to generate at least one of a particular color, design, grain width, or grain pattern.

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

12 . The method of claim 11 , the mixture of material including a metal.

13 . A method of binder jetting additive manufacturing for veneer applications, comprising:
loading a mixture of material into one or more feed boxes of a binder jetting additive manufacturing device, the mixture of material including wood product; depositing a layer of the mixture of material into a working chamber of the binder jetting additive manufacturing device; actuating a working surface of the working chamber; and depositing an additional layer of the mixture of material into the working chamber of the binder jetting additive manufacturing device to form an additional portion of the veneer product.

14 . The method of claim 13 , further comprising:
applying a coating to the layer of the mixture of material; and curing the coating applied to the layer of the mixture of material to form a first portion of the veneer product.

15 . The method of claim 14 , further comprising:
applying an additional coating to the additional layer of the mixture of material; and curing the additional coating applied to the additional layer of the mixture of material to form the additional portion of the veneer product.
