Annealing 3D Printed Parts

Annealing Printed Parts:  If needed, 3d printed parts may be annealed in a hot-air oven to reduce any printed-in stresses that may be present in the part.  Printed-in stresses may occur in any plastic and may result in lower than expected mechanical properties.  If this is an issue with your part, then you can follow the simple 5-step ramp up/down process for annealing  parts.

Step 1:  Place printed parts in cool, room-temp oven.
Step 2.  Set temp to 300°F and allow to stabilize for 1 hour.  
Step 2:  After 1 hour at 300°F, increase oven temp to 400°F and allow to stabilize 1 additional hour.  
Step 3:  After 1 hour at 400°F, reduce heat back to 300°F and allow to stabilize for 30 minutes.  
Step 4:  After 30 minutes, turn off oven heat and allow printed parts to return to room temp inside the oven as it cools.
