Laser beam optics and scanning areas ,
including the fully-enclosed Image Processing
Module (IPM)—where the laser beam
originates—and the interior of the process
chamber, into which the beam projects. The IPM
and process chamber are designed to minimize
hazards such as burns, eye injury, and fire in the
following ways:
✓
The IPM optics and laser beam duct (at the
top of the process chamber, below the
removable laser window) prevents the laser
beam from being aimed outside the process
chamber.
✓
The fully enclosed process chamber blocks
laser radiation from escaping to the outside.
✓
The process chamber window material also
blocks laser radiation so you can safely
observe the part bed during a build.
Other Active Safety Features
✓
The Breakout
Station (BOS),
coupled with the
Dust Collector , removes airborne powder
during part breakout in accordance with
standard industrial ventilation practices.
✓
An overpressure sensor line monitors the
pressure in the Intelligent Powder Cartridge
(IPC) when it is connected to the Integrated
Recycling Station (IRS). This prevents IPC
container ruptures and accidental material
leakage.
✓
A room oxygen monitor automatically
initiates SLS system shutdown when it
detects too little oxygen in the room.
✓
Software in the SLS system , IRS
and
BOS
automatically initiates immediate equipment
shutdown if certain unsafe conditions are
detected during operation.
