Did you know that reducing print temperature at the interfaces between supports can make them much easier to remove? With this trick, you can use a lower temperature to make up for smaller Z separation between the supports and your part, thus giving you cleaner looking supported surfaces without making the supports too difficult to remove. Or you can use a low temperature and a larger Z separation to make the supports come off very easily without sacrificing much surface quality.

To use this model, enable supports, set the Z separation distance how you like, then set only the support interface layers to print at progressively lower temperatures as you move up the tower. So for PLA, it would look something like this:

• Layers 1-25: 230C
• Layer 26: 220C
• Layers 27-74: 230C
• Layer 75: 220C
• Layers 76-99: 230C
• Layer 100: 210C
• Layers 101-148: 230C
• Layer 149: 210C
• Layers 150-173: 230C
• Layer 174: 200C
• Layers 175-222: 230C
• Layer 223: 200C
• Layers 224-247: 230C
• Layer 248: 190C
• Layers 249-296: 230C
• Layer 297: 190C
• Layers 298-321: 230C
• Layer 322: 180C
• Layers 323-370: 230C
• Layer 371: 180C
• Layers 372-395: 230C

Then remove all the supports and find the section highest up the tower that printed without any significant stringing. The temperature that corresponds with that section is the section you should print your support interfaces at. See photos for examples.
