MACHINE PREPARATION
Loading the feeding piston
Operations described below complement and follow on from the Preparation Assistant "Step 3 : Loading powder" on page
41.
WARNING: REACTIVE POWDERS
THE MANUFACTURING CHAMBER MUST BE INERT BEFORE POWDER MANIPULATION (O
2
LEVEL 1%
MAXIMUM).
Before the rst use of metal powder, ensure absence of humidity in the powder, which would affect its ow. 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.
