Powder Management System
(PMS) network and
database application
that enables powder
transfers between
SLS
equipment, logs data
about every transfer, and helps prevent
contamination of the
SLS® system powder
supply.
PowderNet 3D Systems’
proprietary network
that interconnects
SLS
equipment and carries
powder transfer
messages and data.
PowderNet uses the IRS
as its server, or hub. All powder transfer
messages go through the IRS to client BOS
and SLS system(s). The IRS sends powder
transfer data over PowderNet to the APMU
database in an
SLS process for logging.
powder transporter An air-driven powder
pump in the IRS , BOS , or SLS® system at the
head end of a powder transport tube .
powder transport hopper Chute below the
