Printing With Specialty Powders; Inert Gas Connection To The Printer - SINTERIT LISA X Original User Manual

11. PRINTING WITH SPECIALTY POWDERS

11.1 Inert gas connection to the printer

Certain powders used in the Sinterit Lisa X printer need a protective atmosphere. In this situation, an inert gas connection
is required. Powders in the Sinterit range that require an inert gas connection are PA11 Onyx, PA11 CF and PA11 ESD.
WARNING!
• The built-in oxygen level sensor is not a certified safety device and cannot be
used as the sole alarm in the event of an emergency. Sinterit printers with an
inert gas control system may only be used in well-ventilated areas.
• If the alarm is triggered, turn on the ventilation system or open the windows
and leave the room immediately.
• If you feel any suspicious symptoms, immediately leave the room and go
outside/to a well-ventilated room.
WARNING!
• The Lisa X printer with the inert gas installation should only be operated in a
well-ventilated space.
• Do not inhale the gas.
• Danger of unsealing – inert gasses displace oxygen from the air. Low enough
oxygen concentrations may cause loss of consciousness or even death by
asphyxiation.
WARNING!
Many of the specialty powders are potentially hazardous to health if mishandled.
Please consult Chapter 2.7.1 Working with hazardous and potentially hazardous
powders before proceeding.
1. Connect the source of inert gas to the gas inlet nipple on the back of the printer. It is a quick connect fitting (fig. 11.1).
2. On the main menu screen, in the SETTINGS tab, go to MORE OPTIONS.
3. Under the ACCESSORIES tab, switch to ON next to INERT GAS (fig. 11.2).
4. Start the printing process. The process is no different than the process outlined in Chapters 6-9.

IMPORTANT!
• The inert gas source may safely be connected even if the printer is turned off. The connection
is equipped with an electronic safety valve.
• Make sure that the inert gas pressure remains between 4 and 8 [bar] / 58 to 116 [psi] throughout
the whole process. Please note that it may fluctuate if a gas tank and a pressure regulator are
in use.
