3. Heating element
The internal chamber temperature can be controlled. This has the following characteristics:
• Max. internal chamber temperature: 70 °C
• Control accuracy: ±10 °C
• Heating element power rating: 1200 Watts
4. Vacuum cleaner hose
The printer is equipped with a vacuum cleaner hose that can be operated only if connected to an external powder recycling
system. The vacuum cleaner can be used to clean the manufacturing area. The vacuum cleaner hose connection is located
on the left-hand side of the printer.
5. Oxygen analyser sensor
The printer is equipped with an oxygen analyzer that monitors the level of oxygen continuously (value is expressed in
percent till 1% and in ppm below).
6. Lens cleaner and lens trap
A ltering unit is tted on the system to avoid particles and fumes from the sintering process being deposited onto the lens.
A gas ow sweeps permanently the underside of the lens trap; this airow is ltered using a lter cartridge. The particles
are stopped by the cartridge membrane and stored in a collector.
Caution : the lens lter must be replaced regularly. Consult the Maintenance section for the
recommended maintenance interval and details on how to replace the lter.
A lens trap completes the cleaning system. It is open only during sintering.
C. Laser assembly
The main optical devices are :
• A ber laser source: continuous operation, single mode, power at the collimator output 300W, wavelength in the short-
wave infrared range (approx. 1070 nm),
• A collimator: outlet beam diameter at 1 / e ² 15 mm,
• A scanner head,
• A at eld F-Theta lens (420mm focus length). See note.
