How to Anneal our Tough Pro PLA+

Our Tough Pro PLA+ is a tough, engineering grade PLA that can stand up to high impacts and high temperatures. Straight off of the build plate our Tough Pro PLA+ gives you 8.8x higher impact strength than a standard PLA. 

Tough Pro PLA+ uses virgin NatureWorks Ingeo 3D870 resin, which was engineered to deliver thermal and mechanical properties similar to ABS in an eco-friendly PLA package. 

This grade of PLA can be annealed after printing to further crystalize the material, further improving its thermal and mechanical properties. 

To anneal your Tough Pro PLA+ parts: 

1. The most reliable method is to use either an oven or toaster oven.
2. Preheat your oven to 110 - 120°C (230 - 248°F). 
3. Place your print on a baking sheet or baking dish, and place this in the oven.
4. Allow your part to anneal for 30 - 60 minutes. Parts printed with near solid infill, or many walls may require slightly longer for the heat to penetrate all the way to the core of the part. 
5. Turn the oven off.
6. It is best to allow the part to slowly cool back down inside the oven, rather than removing it immediately, to prevent rapid temperature change causing warping. 

Shrinkage and/or warping may occur; the degree of which will be dependent on part geometry.
