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.

Binder jetting additive manufacturing for veneer applications

A method of depositing powder in an additive manufacturing system includes driving a recoater along a drive axis and oscillating the recoater along an oscillation axis. The recoater is oscillated while the recoater is driven along the drive axis to overcome the effect of one or more particle movement restriction mechanisms for smoothing powder deposited in a build chamber of an additive manufacturing system.

Additive manufacturing systems and methods

A blade changer includes a housing with a port, a magazine supported within the housing, and a manipulator. The manipulator is operably associated with the magazine and has a reach extending beyond the port to interchange re-coater blades between the magazine and an additive manufacturing system coupled to the port. Additive manufacturing systems and methods of interchanging a deployed re-coater blade with a staged re-coater blade are also described.

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.

Laminated object additive manufacturing for veneer applications

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.

Extrusion additive manufacturing for veneer applications

A method including filling an internal passage of an additively manufactured (AM) article with a state change fluid, causing the state change fluid to change from a first state having a first viscosity to a second state that is either solid or has a second viscosity that is higher than the first viscosity within the internal passage, causing the state change fluid to change back from the second state to the first state, removing residual powder from the additively manufactured article by flushing the state change fluid from the internal passage, measuring electrical impedance of a piezoelectric wafer connected to the additively manufactured article, and determining that more than a threshold amount of residual powder remains within the AM article based on the measured electrical impendence of the additively manufactured article being outside of a selected range from an expected impendence value.
