Tree branch angle

How far the tree support's branches can lean from vertical. A bigger angle reaches farther and steers around the part better; too much, and the branches themselves print badly.

Not always visible. In Bambu Studio this setting only shows up when “Enable support” is on and “Type” is “tree(auto)” or “tree(manual)”. See Enable support, Type.

How it works

A branch is also an overhang (something sticking out into the air): if it leans too much, each layer sticks out too far from the one below and the branch fails. At 45°, branches lean just enough to merge into a few trunks and move away from the part.

With a small angle, branches come down almost straight: they're very solid, but more trunks are needed and sometimes they can't move away from the part.

When to change it

  • For almost anything: 45°, the profile value.
  • Branches come out ugly or break, for example with a material that droops like PETG: 30–35°.
  • A figure with outstretched arms, far from anywhere the support could rest: 50–55°.

Watch out for

  • It only exists for tree supports.
  • The maximum is 60°: beyond that, no branch holds itself up.

What Bambu Studio says

This setting determines the maximum overhang angle that t he branches of tree support allowed to make.If the angle is increased, the branches can be printed more horizontally, allowing them to reach farther.
