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.

Embodiments disclosed herein describe a method of fabricating soft, flexible fibers using a 3D printer having an extrusion head. Embodiments of the method further include termination techniques to allow a series of fibers to be fabricated on the same object. Aspects of the certain embodiments offer a range of design parameters for controlling the properties of single strands and also of bundles of fibers. The method extends the capabilities of 3D printing without requiring any new hardware.

It is disclosed a process and an apparatus for manufacturing a figure of eight cable. An extrusion head has separate extrusion dies extruding in parallel a first and second outer sheath around a first and second core, respectively, so as to provide two separate cable elements having respective longitudinal axes laying in a first plane. While the outer sheaths are in a softened state, the cable elements are passed in parallel through a twisting die which causes their longitudinal axes to lay in a second plane forming a predetermined twisting angle with respect to the first plane. This twisting causes the outer sheaths to join together, thereby forming a figure of eight cable.
