A method of extrusion additive manufacturing for veneer applications may include, but is not limited to, loading material into an extruder, generating a mixture from the material, and fabricating the veneer product. Fabricating the veneer product may include depositing a first portion of the mixture on a working surface of the extruder, actuating the working surface, and depositing an additional portion of the mixture on the working surface of the extruder proximate to the first position of the mixture deposited on the working surface. Where the first portion of the mixture and the additional portion of the mixture form a first layer of the veneer product, fabricating the veneer product may include actuating a nozzle of the extruder and depositing an additional layer of the mixture on the first layer of the veneer product. The material may include wood product and a binder.

The present invention relates to a lignin-based phenolic resin, particularly useful in the manufacture of oriented strand boards (OSB).

A process for the production of OSB wood-based panels including: a) producing wood strands from suitable wood logs; b) treating at least part of the wood strands with steam at a temperature between 80° C. and 120° C. and a pressure between 0.5 bar and 2 bar; c) drying the steam-treated wood strands; d) gluing the steam-treated and dried wood strands and, optionally, gluing the non-steam treated wood strands with at least one binder; e) scattering the glued wood strands onto a conveyor belt; and f) pressing the glued wood strands into an OSB wood-based board. The steam treatment takes place after the wood strands have been produced and made available, or after the wood strands have been sifted and separated according to the use of the wood strands for the middle and top layers of the panel. Also, an OSB wood-based panel made using the process.

A method is provided comprising: providing particulate material comprising or consisting of particulate wooden material, producing glued particulate wooden material by applying an adhesive to the particulate wooden material, forming a spreading material mat by homogeneously spreading the glued particulate material onto a conveyor on which the spread glued particulate material is conveyed in a conveying direction, and producing a board by pressing the spreading material mat during conveying on the conveyor. Furthermore, a reinforcement material is applied to the spread glued particulate material perpendicular to the conveying direction during forming the spreading material mat and/or after forming the spreading material mat before any pressing of the spreading material mat such that the spreading material mat has at least one longitudinal reinforcement zone containing the reinforcement material. Boards can be obtained, from which panels can be produced having reinforced longitudinal and/or transversal edges.

Disclosed is a process for the treatment of wood strands suitable for the manufacture of OSB boards, in which the wood strands are treated with steam without drying after extraction, the steam being passed over the wood strands at a temperature between 80° C. and 120° C. and a pressure between 0.5 bar and 2 bar. Also disclosed is a process for the production of OSB wood-based boards including the steps of a) producing wood strands from suitable wood logs; b) treating at least part of the wood strands with steam; c) drying the steam-treated wood strands; d) gluing the steam-treated and dried wood strands and gluing the non-steam-treated wood strands with at least one binder; e) scattering the glued wood strands onto a conveyor belt; and f) pressing the glued wood strands into an OSB wood-based board.
