Beschreibung
Zusammenfassung:	An ablative support material for providing support to a primary material during a directed energy deposition (DED) process includes an ablative filler including a melting point that is at least about ten percent higher than a melting point of the primary material. The ablative support material is configured to provide mechanical support to the ablative support material during the DED process. The ablative support material includes an amount of the ablative filler that is at least equal to a mechanical percolation threshold of the ablative filler in the polymer binder.
