6.3 Monthly

6.3.1 Check Pressure Levels

3D Systems highly recommends to check the pressure levels of

the incoming supply of argon and compressed air monthly.
Check the pressure gauges at the rear of the machine. The

pressure level for argon should be:

• Compressed air: between 6 to 10 bar (87 to 145 psi)
• Argon: between 4 to 6 bar (58 to 87 psi)

6.3.2 Check Emergency Off Buttons

Perform a monthly check of the operation of the emergency off buttons on the DMP Flex 350 system. The DMP Flex 350 system

is equipped with four (4) emergency off buttons (circled in red in the image below):

• 1 x on the control panel of the printer
• 1 x on the enable switch (located at the rear control panel)

Press each emergency off button to instantly activate the safety circuit of the entire DMP Flex 350 system.

WARNING: IN THE HIGHLY UNLIKELY EVENT THAT THE DMP FLEX 350 SYSTEM DOES NOT ACTIVATE THE

SAFETY CIRCUIT AFTER PRESSING THE EMERGENCY OFF BUTTON, CONTACT THE 3D SYSTEMS TECH SUPPORT

IMMEDIATELY!

To restart the DMP Flex 350 system after activating the safety circuit, refer to

§5.8.3 Restart after emergency stop
