Initial layer infill speed
How fast the solid infill of the first layer is printed. It can go faster than that layer's walls, but it's still slow: raising it saves time on big bases, lowering it improves grip.
How it works
The first layer has two kinds of line: the walls, which trace the outline and are printed very slowly, and the infill that covers the inside. Since the infill is enclosed by the walls and has a lot of contact with the plate, it can go twice as fast without coming loose.
At 105 mm/s (the factory profile value) it still runs at less than half the speed of the solid infill on the other layers.
When to change it
- A drawer organizer or a tray with a large, solid base, where the first layer takes ages: raise it to 150 mm/s.
- A base that comes out with grooves or with beads of plastic that don't join each other: lower it to 60 mm/s.
Typical values
| Value | What for |
|---|---|
| 60 | Maximum grip |
| 105 | Defaultdefault |
| 150 | Large bases and grippy plates |
Watch out for
- First-layer infill that's too fast leaves visible streaks between the lines on the bottom of the part.
