Inerting the manufacturing chamber

The machine needs a gas to create an inert atmosphere in the manufacturing chamber . This cover gas inhibits any potential

rapid combustion of particulate matter during the process .

The inerting is required for oxidizable or flammable materials, and for better build quality.

When launching, the inerting process will automatically perform the 2 following phases in this order :

manufacturing chamber inerting at first, then external filter vessel inerting. Make sure the filter is well

connected to the printer before starting the inerting process .

To perform the inerting, follow the instructions of the Preparation Assistant "Step 8 : Loading of the manufacturing file and

inerting" on page 45 .

The start of manufacturing shall be carried out only when the oxygen level is below the required value .

START A MANUFACTURING PROCESS

WARNING: THE MANUFACTURING CHAMBER AND PROCESS FILTER MUST BE INERTED BEFORE STARTING

ANY JOB . REFER TO SECTION "INERTING THE MANUFACTURING CHAMBER" ON PAGE 63 .

Operations described below complement instructions from the "Manufacturing menu" on page 47 .

When all the steps of the machine preparation have been completed, the start procedure of a job is as follows:

•

Run the sintering of layer #0 .

•

Run the layering of layer #1 . Repeat this operation if the layer obtained is not correct (lack of powder for example) .

•

Run the sintering of layer #1 .

•

Run the layering of layer #2 . Repeat this operation if the layer obtained is not correct (lack of powder for example) .

•

Continue step by step as described above, up to layer #5 .

•

If all five layers completed successfully on the first try, then start the full manufacturing in automatic mode.

Make sure that during the first 10 layers, there is no short feed.
