Solid state manufacturing tools and methods using them

A tool for depositing solid state feedstock material, the tool comprising:

• a first tool member comprising a first inlet, a first outlet, and a first channel between the first inlet and the first outlet, wherein the first inlet is configured to receive the solid state feedstock material;
• and
• a second tool member comprising a second inlet, a second outlet, and a second channel between the second inlet and the second outlet, the second tool member configured to couple to the first tool member to permit the solid state feedstock material to be provided from the first tool member to the second tool member through the first channel and the first outlet of the first tool member and into the second inlet and the second channel of the second tool member, wherein the second channel of the second tool member comprises a draft angle at the second outlet of the second tool member to permit deposition of the solid state feedstock material from the second outlet onto a surface without using any lubricant on the solid state feedstock material, wherein the second tool member comprises a face at the second outlet that is configured to contact the surface during rotation of the tool to generate friction between the face and the contacted surface while applying force to the solid state feedstock material in the rotating tool to deform the solid state feedstock material exiting the second channel at the second outlet to deposit the exiting solid state feedstock material on the surface in a solid state without any lubricant on the exiting solid state feedstock material, wherein the first outlet of the first tool member slidingly engages the second inlet of the second tool member when the first tool member is reversibly coupled to the second tool member.

• and
• a third tool member comprising a third inlet, a third outlet, and a third channel between the third inlet and the third outlet, wherein the third tool member is configured to reversibly couple to the first tool member at the first inlet end of the first tool member to permit solid state feedstock material in the third channel to be provided into the first inlet and into the first channel of the first tool member.
