Print preparation
3D Print Orientation Planner
Compare sensible STL and 3MF orientations locally before slicing. Review printer fit, downward-facing geometry and estimated first-layer contact in one place.

Your STL or 3MF stays in this browser. It is not uploaded or changed.
What this planner can and cannot decide
It compares six axis-aligned build directions. It does not test every angled rotation, generate supports, predict warping or replace slicer preview. Confirm the chosen orientation with the intended printer, material and slicer settings.
