 Placeholder: We recommend 120C annealing, which produces parts good to ~100C. Higher temperatures are more difficult to process PET parts with, but yield parts with greater temperature resistance.
-Make sure you calibrate your printer to the post-processed product (post annealing). Generally, you can expect negligible Z-axis shrink with approximately 1% shrink on the X and Y axes.
