Abstract: A method of extruding a material, comprising providing the material into an extrusion chamber of an extrusion apparatus, wherein the extrusion chamber comprises an extrusion orifice and the extrusion apparatus comprises a first compression element and a second compression element in communication with the interior of the extrusion chamber, the first and second compression elements being independently movable relative to the extrusion chamber, moving at least one of the first and second compression elements to compress the material within the extrusion chamber and cause a velocity gradient in the extrusion material across the extrusion orifice and extruding the material through the extrusion orifice such that the velocity gradient forms an extrudate with a curved profile.
