How To Anneal Pro PLA+

To get the maximum strength out of your 3D printed part, we recommend a post-printing annealing procedure that should be done in an oven at a range of 176-266 F (80 – 130 C) to promote increased crystallization and further improve the heat deflection temperature.

For best results:

  1. Preheat the oven or toaster oven.
  2. Place print on a room temperature baking sheet.
  3. Place the baking sheet into oven/toaster oven.
  4. Wait 30-60 minutes for annealing to complete
    1. You may see the print take on a milky/matte/opaque color transformation.
  5. Turn the oven off.
  6. Wait for oven to cool before removing print.

Shrinkage and/or warping may occur. The degree of shrinkage/warping depends heavily on the part geometry.
