Claim:
1. A friction-based fabrication tool comprising: a deposit material; a tool body comprising a hollow interior for housing the deposit material disposed therein prior to deposition on a substrate; wherein the interior of the tool body is shaped to exert a normal force on the deposit material disposed therein for rotating the deposit material during rotation of the tool body at a speed sufficient for imposing frictional heating of the deposit material against the substrate, such that the deposit material and the throat have correspondingly shaped and sized cross sections along the entire length of the portion of the deposit material that is disposed in the throat; wherein the tool body is capable of dispensing the deposit material through the tool body onto the substrate and is capable of rotating and translating relative to the substrate; and wherein the tool body comprises a shoulder surface with a flat surface geometry or a surface geometry with structure for enhancing mechanical stirring of the deposit material, which shoulder surface is operably configured for trapping the deposit material in a volume between the shoulder and the substrate and for forming and shearing a surface of a deposit material on the substrate; wherein the deposit material is adapted for continuous deposition of the deposit material on the substrate during translation of the tool body relative to the substrate.
