MACHINE PREPARATION
Introduction
In order to keep an inert atmosphere inside the manufacturing chamber, the operator needs to use the glove doors across
the attached gloves for all manipulation inside the manufacturing area . The glove doors are located behind the front doors,
as well as the airlock door .
Caution : always use appropriate safety equipment when operating the printer . Personal Protective
Equipment (PPE) must be used to protect the user against health or safety risks during working tasks .
Wear disposable rubber gloves, anti-static coverall, anti-static safety shoes and safety glass . Wear
disposable dust mask rated FFP3 or N99 level protection at minimum ; we recommend the use of powered
air-purifying respirator .
• Front doors
To open the front doors, the operator must at first unlock by pressing the key button from the control panel (see "External
control panel" on page 27) .
If the sensor does not detect the well closing of the front doors, the printer will be in "UNLOCK" mode (see
"User interface" on page 33) as long as the front doors will not be closed . Make sure to close the front
doors so that the printer will be in "READY" mode (i .e operational) .
Caution: do not close the front doors on the gloves, this may damage the gloves . The gloves must be
checked regularly . Consult the Maintenance section for the recommended maintenance interval and
details on how to check the gloves .
• Glove doors
To describe the opening/closing mechanism of the glove doors, the gloves have been removed on the following figures.
In normal operation, the opening/closing of the glove doors must be performed with the gloves .
• To open the glove door, rotate the Palm Grip in a counterlockwise direction, then rotate the Flat Bar a quarter-turn .
The glove doors are opening towards the inside of the chamber . The position of the Flat Bar are used to detect the
well closing of the glove doors .
• To close the glove door, make sure the Flat Bar is placed at first vertically. Then fully close the glove door, and place
the Flat Bar horizontally (as shown on the left figure). Make sure to tighten securily the Palm Grip while the Flat Bar
is placed horizontally .
