Multiple wiping bodies bend a tensioned metal wire into bow sections for steady cleaning, contaminant extraction, and cooling.
Electric current melts metal wire at the contact point to print 3D parts faster, with less waste, lower heat input, and no powder handling.
Electric current heats metal wire at the contact point to deposit molten droplets, cutting powder waste, heat input, and build time.
A tapered conductive member spreads Joule heating across interior and edge surfaces to produce stronger, more uniform resistive welds.
Electric current heats metal wire into droplets at the contact point, avoiding powder spreading, laser hazards, and metal waste.
