5 . Fume cleaner device
This device consists of a blower (located between the airlock door and the collecting tank) and a suction tube on the left of
the sintering piston. It generates a gas flow for evacuating sintering particles and fumes which can negatively affect the
process .
6 . Heating element
The internal chamber temperature can be heated via a resistor with the following characteristics:
• Max . internal chamber temperature: 70 °C
• Control accuracy: ±10 °C
• Heating element power rating: 4100 Watts
7 . Oxygen analyser sensor
The ProX DMP300 machine is equipped with an oxygen analyzer that monitors the level of oxygen continuously (value is
®
expressed in percent till 1% and in ppm bellow) .
8 . Powder tamping module
The tamping piston is used for leveling and tamping the powder in the feeding piston during machine preparation, and for
closing the feeding piston during recycling process .
9 . Lens cleaner and lens trap
A filtering unit is fitted on the system to avoid particles and fumes from the sintering process being deposited onto the lens.
A gas flow sweeps permanently the underside of the lens trap; this airflow is filtered using a filter cartridge. The particles
are stopped by the cartridge membrane and stored in a collector .
Caution : the lens filter must be replaced regularly. Consult the Maintenance section for the
recommended maintenance interval and details on how to replace the filter.
A lens trap completes the cleaning system . It is open only during sintering .
10 . Vacuum cleaner
Inside the manufacturing chamber, the operator can use the internal vacuum cleaner for cleaning the manufacturing area .
The powder collected is processed in the recycling system .
