Apparatus for discharging sheets having skins on them and different patterns, characteristics, and properties. One or more rollers, belts, plates, or combinations thereof, having cavities and projections of desired patterns formed on their surfaces, pass through low pressure liquefied extrudable materials to be bathed thereby and pass by another surface(s). Heating or cooling is applied as appropriate to the roller(s), plate(s), belt(s), to form a skin on the extrudate and/or set same. A distributed low pressure, mixed orientation, low gas, liquefied extrudable material is generated using a vented barrel assembly and manifold mechanism. By using a dynamic moving die surface, bathed in a low pressure material chamber, rather than extrudable material forced through a fixed die opening as is normally done in extrusion processes, a product with low stress and one that exhibits isotropic properties results. Additionally, the dynamic moving die surface can be used to embed and fuse useful patterns, circuits, or post-operation films.
