Puzzle prints are unusual: a large flat plate, several filament changes, and dozens of small interlocking pieces that all have to survive removal from the bed. These Bambu Studio settings consistently produce clean results.
Quality settings
Layer height 0.08 mm is the sweet spot: color transitions land close together, so image edges look sharp instead of terraced. First layer can stay at the same height for accurate color-change math.
Prime tower width around 45 mm keeps colors clean after each change — a 20 mm tower is too small when several swaps happen in a short stack of layers.
Adhesion and removal
A textured PEI plate releases dozens of pieces without a fight. If you use a brim for the display frame, keep 10+ mm distance between objects so brims never touch.
Let the plate cool fully before flexing — small pieces pop off intact instead of leaving their knobs behind.
Start from a correct project
The easiest path: generate the puzzle as a complete 3MF project with these settings and the filament change layers already set. Slice, hit print, swap when prompted — that's the whole workflow.
