Abstract
A system for creating a second quantity of sinterable powder particles which have sizes falling within a second size range, from a first quantity of sinterable powder particles having sizes falling within a first size range, and where the sizes of the powder particles in the second size range are all larger than those in the first size range. In one embodiment the system has a heating component responsive to a predetermined temperature/time heating profile, which heats the first quantity of powder particles using the temperature/time heating profile, to cause partial sintering of the powder particles, which creates a new plurality of powder particles which have an increased dimension. A movement component is incorporated to at least one of separate the new powder particles from remaining ones of the powder particles of the first quantity of powder particles, or to further process the new plurality of powder particles, such that the new plurality of powder particles represents the second quantity of sinterable powder particles.
