Enable support
In Bambu Studio, the profile 0.20mm Standard @BBL A1 sets it toNo
The main switch for supports: throwaway scaffolding printed under the parts that hang in the air. Without it, whatever sticks out too far falls; with it, the print takes longer, uses more plastic and leaves marks when you remove it.
How it works
Hot plastic needs something underneath. A wall that leans up to about 45° holds itself up, because each layer rests partly on the one below. Past that angle, or on an arm that sticks straight out, the line is printed in mid-air and droops. Support is printed under those areas and snapped off at the end.
With the box checked, the slicer looks for overhangs (parts that stick out with nothing below) based on the “Threshold angle” and adds support wherever it's needed, of the type and style you pick below. With the box unchecked, no support is generated at all, not even what you paint by hand; only the raft, if you turn it on, still works.
When to change it
- A figure with arms, a head or a tail in the air, the roof of a box, or a large horizontal hole: turn it on.
- Parts designed to print without overhangs, like most organizers and hooks “designed for 3D printing”: leave it off and save time and cleanup.
- Before turning it on, try rotating the part: a good orientation avoids more support than any setting.
Typical values
| Value | What for |
|---|---|
| Off | Default; parts without overhangsdefault |
| On | Figures, arms, roofs, large holes |
Watch out for
- The face that rests on support never comes out as nice as the one resting on the plate: point it where it won't be seen.
- If you turn it on and the program doesn't add support where you expected, check “Threshold angle” and “On build plate only”.
- The grayed-out options on this tab become available when you check this box.
