Abstract
A material deposition head may include a ring configured to rotate about a first body portion and cause axial translation of the first body portion relative to a second body portion, where one or more nozzles are coupled to the first body portion. In some examples, at least one anti-rotation pin may substantially prevent rotation of the first body portion while the first body portion axially translates, and a seal may substantially prevent external contaminants from invading an interior portion of the material deposition head. In addition, a pointer tool attached to the head and an external translational measurement tool may permit measurement of an axial position of the one or more nozzles without requiring disassembly of the head or disruption of a substantially inert environment within which additive manufacturing may proceed. A method of axially translating the first body portion of the head also is disclosed.
