Abstract
Successive layers of a wall of a part are deposited to form a first access channel extending from an exterior of the part to an interior of the part, as well as to form a distribution channel connecting an interior volume of the honeycomb infill to the first access channel. A binder matrix retaining sinterable powder is debound by flowing a debinding fluid through the first access channel and the distribution channel within the interior volume of the honeycomb infill.
