Powder bed
cycle on the control panel (see "Step 6 : Powder bed" on page 37) .
The following steps are displayed on the corresponding cycle .
2 . Check the proper completion of the powder bed sequence (3):
•
Gaps must be filled,
•
Powder must properly cover the area between the two pistons,
•
Powder must be well smoothed on the feeding piston,
•
Plate must be visible in transparency and the screws must
be filled with powder, to not disturb the layers during
manufacturing .
3 . If the powder bed is not properly completed, re-run the powder bed
cycle . Proceed the next section only if the powder bed cycle is properly completed .
