Using The Nitrogen Chamber - SINTERIT Lisa Pro User Manual

These remarks apply to the material PA12 SMOOTH and PA11 ONYX.
In case of FLEXA materials, an increase in laser power results in a printout
stiffening (up to a certain, maximum level).

CAUTION!
Possibility of unsealing - gas has a suffocating effect on people by
displacing oxygen from the air. Too low oxygen concentration in the air can
lead to ​ u nconsciousness and death​ . Inhalation exposure may cause short
breath,
concentrations of gas disorders of orientation, nausea, fainting, loss of
consciousness, death.
Store in a well-ventilated place. Do not inhale gas. Nitrogen is an inert gas, a
natural component of atmospheric air. It is not harmful in the aquatic
environment or soil, its adverse effect is limited to the displacement of oxygen.
A. To print in the nitrogen environment (required for PA11 Onyx), connect the nitrogen
supply to the gas connection (1). It can be connected at anytime, even when the
printer os off, as it has an electrovalve built in.

lowered by decreasing (also by 0.01). The acceptable calibration
scope of laser multiplier is 0.5-3.0.
● As the laser gets weaker, the printout durability get lower as well,
however the quality of details gets better. Similarly: an increase of
laser power strengthens the printout but weakens the quality of details.
