Zero sintering search
Operations described below complement and follow on from the Preparation Assistant "Step 4 : Zero sintering" on page
37.
The zero research is performed with the roller. Please ensure :
The sintering plate must be clean . No dust must be located on its surface . The roller should not get in
touch with any powder during this cycle . Make sure to keep a clean area as described on the section
"Unloading a plate" on page 65
1. Check the sintering plate is clean.
2. Start the
Zero sintering
cycle on the control panel (see "Step 4 : Zero sintering" on page 37).
3. The zero sintering value will then be displayed.
Loading the feeding piston
Operations described below complement and follow on from the Preparation Assistant "Step 5 : Powder loading" on page
WARNING: REACTIVE POWDERS
THE MANUFACTURING CHAMBER MUST BE INERT BEFORE POWDER MANIPULATION (O
2
LEVEL 1%
MAXIMUM) .
Before the first use of metal powder, ensure absence of humidity in the powder, which would affect its flow. That is why
sifting and oven drying are strongly recommended.
Implement the following operations :
•
Sieve the fresh powder once,
•
Place the fresh powder into a large tray in order to obtain a thin layer (maximum 4cm),
•
Place the tray in the oven at 70°C for 24 hours, in order to dry the powder out completely. As a good practice, shake
the powder delicately from time to time in order to speed up the process of moisture loss,
•
Sieve the powder again.
WARNING: REACTIVE POWDERS
DO NOT HEAT THE POWDER IN CASE THE OVEN IS NOT INERT . FLAMMABLE POWDERS ARE PROVIDED IN
SEALED INERT PACKAGING FREE OF HUMIDITY .
1. Start the
Powder loading
cycle on the control panel (see "Step 5 : Powder loading" on page 38).
The following steps are displayed on the corresponding cycle .
2. Position the feeding piston by using the corresponding button from the screen control panel. Make sure there is
enough material to complete the job. To get the amount of material needed to have a successful build, use the
formula= (Total layers)
x (Powder raising during manufacturing). Values are accessible with the Adjuster level, see
section "User level selection" on page 47).
3. Rotate the airlock to OPEN position.
4. Unlock the front doors of the printer and open them.
5. Open the airlock door.
6. Put the powder can with tools (brush and tampling plate) in the airlock (1).
