Tips for Successful Annealing:

  • Precise Temperature Control: Essential to avoid overheating.
  • Test with Small Models: Reduce trial-and-error costs.
  • Allow for Shrinkage: Adjust your design accordingly.
  • Set Temperature: Choose the right temperature for the material.
  • Even Heating: Heat the part uniformly.
  • Hold Time: Maintain constant temperature.
  • Controlled Cooling: Cool gradually for best results.
