Structure Mode

Structure Mode determines whether colour layers are built on one side or both sides of the base plate.

Double-sided

Colour layers are built on both sides of the base, which is useful for tags or hanging pieces that must show artwork from either direction. It increases model height, material use, and sliced layers.

Single-sided

Colour layers remain on one side and the opposite side is the base plate. Relief, fridge-magnet, and other back-dependent features use the single-sided path.

Automatic restrictions

• Relief or Fridge Magnet disables or forces Single-sided geometry.
• 5-Color Extended does not allow Double-sided and switches an existing Double-sided selection back to Single-sided.
• Any change invalidates the previous 3MF and download.

This is model geometry, not the slicer's print-order setting. Inspect the underside in the slicer after generation.
