Steps for Post Processing a Part

Bulk Wax Removal

After job is finished printing, platform should be raised and clamps released.

  1. Lift the entire platform off of the printer.

  1. Place the platform in a freezer for approximately 30 minutes. This will cool the parts and enable them to separate easily from the platform.

NOTE: Placing print platform on a metal surface as shown here speeds up the cooling time.

 

  1. After parts are cooled sufficiently, remove them from the print platform. It may be necessary to use a putty knife to loosen the larger parts.
  2. For stubborn parts you an use a smooth wood block to gently tap parts free of platform.
  3. Keep angle of putty knife below 20 degrees to avoid scraping the platform.

NOTE: Take care not to scratch, groove, dent, or damage parts or platform in the removal process.

  1. Once parts have been removed from platform, place them in a metal basket.

NOTE: Nitrile gloves must be worn when handling all parts that have not been processed.

 

  1. Place the entire basket in a 70°C (158°F) warming oven for 30 minutes or until the wax support material has melted off.

NOTE: Set the basket on top of a drip tray to allow support material to drip off into the tray.

CAUTION: Ensure parts are not stacked on top of one another, a lasting impression may be made from one part to another.

 

  1. Remove parts from oven and wipe off any remaining support material with a paper towel.
