Top interface layers
How many dense layers the support puts right under the part so it rests on something flat. At 0, the part rests on the support's open lines and its underside comes out pitted and wavy.
How it works
The body of the support is an open lattice. If the part sat directly on it, its first lines would sink between the support lines and the underside would come out pitted and wavy. The interface is a sheet of two or three nearly solid layers that closes off that lattice.
More layers give a flatter, more stable platform; each one adds plastic and time, but they peel off just as easily.
When to change it
- For almost anything: 2, the default.
- A helmet or a figure whose underside shows, like a chin or the brim of a hat: 3.
- A quick prototype to check dimensions, where the underside doesn't matter: 1. Don't use 0 unless you know why.
