Beschreibung
Zusammenfassung:	An additive manufacturing metal paste and a method of additive manufacturing using the metal paste is presented. The metal paste includes a first metal component of a first majority-phase structural metal, the first majority-phase structural metal comprising approximately 75 wt. % to approximately 90 wt. % first metal particles having a particle size of approximately 1 micron to approximately 100 microns. The metal paste further includes a second metal component of a second bonding metal, the second bonding metal comprising approximately 3 wt. % to approximately 10 wt. %, the second metal particles having a particle size of approximately 3 nanometers to approximately 100 nanometers. The paste further includes a binder having a weight percentage of approximately 2 wt. % to approximately 15 wt. % wherein the metal paste has a sintering temperature of less than approximately 300° C.
