The SLS system builds parts in the removable
RCM. It performs builds in a heated, nitrogen-
inerted internal process chamber the receives
powder from the IRS. An feed hopper dispenses
DuraForm powder material on a sweeper in the
process chamber. Powder is wiped off the
sweeper, preheated, then a roller spreads the
powder over the part bed. A laser mounted on top of the SLS system scans
the bed of powder. After scanning, the RCM,
(under control of Sinter program running in the
SLS system computer), drops the RCM part piston
one layer height.
