Support interface speed
How fast the interface is printed: the dense support layers that touch the part. It runs slower than the rest of the support, because it decides whether the underside comes out smooth and whether the support peels off cleanly.
How it works
The interface is the tightly packed sheet right under the part. The part rests on it and copies its texture, so its lines should come out flat and even. That's why it prints at 80 mm/s by default, well below the support body (150 mm/s).
If the interface uses a special support filament, going slow also helps it come away cleanly.
When to change it
- Most parts: leave 80.
- A figure whose chin or arms rest on support and come out rough once you remove it: lower to 50.
- Support nobody will see (for example, inside a box): you can raise it to 120 and save some time.
Typical values
| Value | What for |
|---|---|
| 50 | Smoother undersides |
| 80 | Defaultdefault |
| 120 | Faster; rougher finish |
Watch out for
- If the support leaves marks, check “Top Z distance” first: it matters more than this speed.
