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.
The inerting process must follow the 2 phases in this order: manufacturing chamber inerting at first, then
process filter inerting. Do not activate the lens cleaner blower if the process filter is not connected to the
printer. 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 40 .
The start of manufacturing shall be carried out only when the oxygen level is below the required value .
Refer to the Adjuster User Level appendix (see "User level selection" on page 45) for details .
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 54 .
Operations described below complement instructions from the "Manufacturing menu" on page 42 .
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 (the layering of layer #0 has been established during the step "Creating the powder
bed" on page 51) .
•
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.
