Abstract
A consumable polymeric based powder mixture may include a plurality of polymeric based particles that have a unitary construction. At least about 80% of the plurality of polymeric based particles may further have a generally cylindrical shape. The plurality of polymeric based particles may further have a particle length distribution span (PLDS) of not greater than about 1.2, where PLDS is equal to (L80−L20)/L50.

A consumable polymeric based powder mixture, the mixture comprising a plurality of polymeric based particles having a unitary construction, wherein at least about 80% of the plurality of polymeric based particles have a generally cylindrical shape.
A consumable polymeric based powder mixture, the mixture comprising a plurality of polymeric based particles, wherein at least about 80% of the plurality of polymeric based particles have a generally cylindrical shape and wherein the plurality of polymeric based particles have a particle length distribution span (PLDS) of not greater than about 1.2, where PLDS is equal to (L80-L20)/L50.
A method of forming a consumable polymeric based powder mixture, the method comprising:
- providing a plurality of polymeric based tows comprising a plurality of polymeric based fibers;
- aggregating the plurality of polymeric based tows into an aggregated polymeric based tow;
- and
- successively forming a plurality of polymeric based particles from the aggregated polymeric based tow,
- wherein at least a majority of the polymeric based particles of the plurality of polymeric based particles has a unitary construction and wherein at least about 80% of the plurality of polymeric based particles have a generally cylindrical shape.
