Wash Jobs


Topics:


The Wash Jobs page provides a place for you to record initial and end masses of parts, allowing you to track your parts through the Wash-1 debinding process and helping you determine when a part is fully debound and ready for sintering. You can find this page by clicking the Wash Jobs link in the sidebar on the left-hand side of the page. Note that the Wash Jobs and Sinter Jobs links will only appear if there is at least one Metal X System device registered to your organization.

When an online Metal X printer completes a print, the parts are immediately listed on the Wash Jobs page. Parts that are exported for offline printing are also sent to the Wash Jobs page. For more information on printing metal parts, please see Printing a Metal Part.

Note that the Wash-1 operates offline and does not connect directly to Eiger; note also that Eiger only recommends minimum Wash-1 chemical debinding times. It is important to fully debind each part in the Wash-1, to avoid potentially damaging wax buildup in the furnace. The Opteon SF79 solvent will not damage the part, and a printed part cannot be over-washed. However, a part that remains in the immersion chamber for an extended period may be jostled and damaged by contact with other parts or by the Wash-1 operator. We recommend carefully tracking wash times and batching wash cycles to avoid physical damage.

You must also confirm Eiger’s recommended wash times by carefully weighing parts after each wash cycle and moving them to the Sinter-1 only when completely washed. See the flowchart below.

Note: To calculate % mass loss, subtract the mass of the washed (brown) part from the mass of the unwashed (green) part, then divide by the mass of the green part.

By default, the Wash Jobs page displays four tables: Ready to Wash, Washing, Drying, and Wash History. For more information on the role Eiger plays in the wash process, see Track Parts through the Wash Process, below.

Track Parts through the Wash Process

The Wash Jobs page notifies you of how long parts need to wash. This section will guide you on how to manually move printed parts through the washing, drying, and wash history processes. The main Wash Jobs page displays a list of printed parts that are ready to be washed. The Wash Time column indicates how long each part should remain in the Wash-1 station to be completely debound.

  1. To begin tracking a part through the wash process, first select which part(s) you want to wash from the Ready to Wash table, then click Wash Selected in the top right corner of the screen.
    Image95891.PNG
  2. Weigh your printed parts on a 0.01g-resolution scale and enter their initial masses into the respective fields in the pop-up window. Eiger will then prompt you to place your selected parts into your Wash-1 station.
    Note: For more detailed information on how to properly load parts into the Wash-1 station, see Loading Green Parts.
    Image95899.PNG
  3. Once all parts have been loaded in the Wash-1 station, press Next to move each selected part to the Washing table and initiate the timer indicating the wash duration of each.
  4. Click Done in the bottom right corner of the pop-up window to return to the main Wash Jobs page.
  5. To view the parts’ progress, scroll down to the Washing table, or click the In Progress tab on the Wash Jobs main screen. The Washing and Drying tables display how long parts have been washing or drying, respectively, in the Wash-1 station.
  6. When the washing timer indicates that the parts have finished washing, transfer the parts to the drying chamber following the instructions in Unloading Parts.
  7. Once you have finished transferring the parts to the drying chamber, select them from the Washing table. Select Dry Selected in the top right corner of the page to indicate that the drying process has begun. The parts will immediately be moved from the Washing table to the Drying table, which will show you how long the part needs to remain in the drying stage. 
    Image95916.PNG
  8. When the drying timer indicates that the parts have completed the drying stage, select the parts in the Drying table and select Mark Selected as Done in the top right corner of the page to send the selected parts to the Wash History table.
    Image95924.PNG
  9. Weigh the dried parts individually and calculate the percentage mass loss of each part, according to the flowchart above.
    • If there is insufficient mass loss: Select Additional Wash Time from the Actions drop-down menu for that part, enter the current brown mass, and begin the wash process again. The part will be moved to the Washing table.
      Image95935.PNG
    • Otherwise, continue on to the next part until all parts have been weighed and assessed for mass loss.
  10. You have the option to insert the final mass of washed parts in the End Mass (g) column of the Wash History table. Click inside the End Mass (g) field for the part in question and type the final mass, in grams. If the final mass does not reflect the full required mass loss, a warning will be displayed to inform you that the part has not been washed properly. See the bullet point under step 9, above.
