How do you remove 3D print supports?

Let the print cool, tear the support out with pliers from a corner, peel the interface off and sand the scar. Bambu Lab says within 2 hours; wear safety glasses.

What overhang angle needs support?

Past 45° from vertical, by the 45° rule. Bambu Studio's 30° and PrusaSlicer's 35° count from horizontal (60°, 55° from vertical); Cura's 50° counts from vertical.

Why are PETG supports so hard to remove?

PETG bonds to itself, so its supports fuse across the default 0.2 mm gap. Raise Top Z distance 0.05 to 0.1 mm at a time, or print the interface in PLA at 0 mm.

Can you print overhangs without supports?

Yes: up to 45° by most design guides (Prusa says 45 to 60°) and across bridges of 5 to 10 mm. Past that, use chamfers, teardrop holes, splits or a new orientation.

Why is my print rough under the supports?

The underside is printed across a gap onto support interface lines and sags between them. Denser interface layers and a gap under the shipped 0.2 mm smooth it.

How do you print with PVA soluble supports?

Load dry PVA as a second filament, make it the support filament and set top Z distance to 0. It dissolves in water in a few hours to overnight.

How do you reduce support material?

Lay the part on its largest flat face, then switch to tree supports: 1.87 g against 3.9 g for normal supports in one published Bambu Studio slice.

Which support interface material works with each filament?

Print only the interface in a material that won't bond: PETG under PLA, PLA under PETG, ABS or ASA under nylon. Makers then allow a 0 mm top Z distance.

What does support on build plate only mean?

Supports may start only on the build plate, never on the model, so an overhang above another part of the print gets none. Every major slicer ships it off.

What should support Z distance be?

0.2 mm top and bottom at 0.2 mm layers, as Bambu Studio, OrcaSlicer and PrusaSlicer ship it; finer profiles go lower. Use 0 only with soluble or support filament.

Why do my supports keep falling over?

Tall, thin supports on a small foot get knocked loose. Widen the first layer (OrcaSlicer 2 mm, PrusaSlicer 3 mm by default), thicken branches, turn on Z hop.

Can you use tree supports with TPU?

Yes, but supports printed in TPU tend to string, collapse and stick. Bambu Lab advises PLA supports at a 0 mm top Z gap; for TPU on TPU, Prusa widens it to 0.3 mm.

What is the difference between tree and normal supports?

Normal supports fill the space under an overhang with straight columns; tree supports branch from a trunk and touch it at 0.8 mm tips, using less filament.

What are supports in 3D printing?

Temporary structures the slicer builds under steep overhangs, long bridges and mid-air islands. Off by default; Bambu Studio supports surfaces under 30° from horizontal.

What is support interface in 3D printing?

The dense layers between a support and the part. Bambu Studio ships 2 top and 2 bottom interface layers, PrusaSlicer 3 top; Cura's base profile leaves it off.

Why are my supports so hard to remove?

The support's top is too close to the part or too solid. Profiles ship a 0.2 mm Top Z distance; Bambu Lab says 0 makes same-filament supports really hard to remove.
