What you approved in Bambu is what we print.
Most fulfilment platforms re-interpret a generic mesh. Makr3D’s default is Faithful 3MF Mode: we honour the project intent embedded in your Bambu or Orca slice, then a human reviews it for print-safety before production.
The difference between a shape and a plan.
An STL is geometry
An STL describes a surface and nothing else. Whoever slices it decides orientation, supports, layer height, colour and profile — so the same file can print very differently from one bureau to the next.
That is fine when you want us to optimise. We slice STL files against validated farm profiles in Recommended Mode.
A 3MF is the plan
A Bambu or Orca 3MF carries the decisions with it: plates, orientation, supports, colour mapping, layer height, nozzle and filament. It is the slice you already dialled in and approved on your own machine.
Makr3D’s default Faithful 3MF Mode attempts to reproduce that plan, so production matches your intent rather than a fresh interpretation.
Your project intent, carried through.

Faithful, but never blind
Faithful does not mean unchecked. Every 3MF still passes a human review gate before production to catch failure-prone, unsafe or unsuitable slices. It is a safety check, not a downgrade of your settings — we flag issues and work with you rather than silently re-slicing.
Recommended Mode fallback
No good 3MF, or you would rather we optimise? In Recommended Mode we slice your STL against validated farm profiles tuned for the Bambu fleet — so beginners get a reliable result without learning to slice, while advanced users keep full 3MF control.
