System and process for creating a three-dimensional part or article by blow molding

A system for blow-molding a three-dimensional article, the system comprising:

• at least two regrind extruder systems, each one of the at least two regrind extruder systems being configured to release a regrind viscous mixture;
• at least two color extruder systems, each one of the at least two color extruder systems being configured to release a color viscous mixture;
• a feedblock configured to receive and combine the at least two regrind viscous mixtures and the at least two color viscous mixtures into a layered stream;
• a forming system for forming a cylindrical blank from the layered stream, the cylindrical blank comprising two circumferential portions, each one of the two circumferential portions having a layered configuration characterized by at least two layers across a cross-section of the cylindrical blank;
• and
• a blow mold configured to receive the cylindrical blank, wherein the cylindrical blank is inflated inside the blow mold to form the three-dimensional article,
• wherein each one of the at least two layers of the two circumferential portions of the cylindrical blank is formed by one of the at least two regrind viscous mixtures and the at least two color viscous mixtures.
