ROTARY POWDER FEED THROUGH APPARATUS

摘要

A device (10) for increasing the uniformity of solids within a solids fabrication system. The invention provides a feed through interface wherein gas entrained powders input from stationary input lines (28) are coupled to a rotating head of the fabrication system via a rotating member (36). The invention eliminates the need to provide additional slack in the feed lines to accommodate head rotation, and therefore reduces feed line bending movements which induce non-uniform feeding of powder to a rotating head.
