1. Download the right file and check its dimensions
Kavi AI provides STL and 3MF downloads after model processing completes. Import the model into your slicer and compare the displayed dimensions with the size selected in Kavi AI. STL does not declare units, so confirm millimeters on import. A downloaded 3MF model is not a ready-made printer profile or a guarantee that your printer settings are included.
2. Inspect the shape from every side
Look beneath the model and around the back. Check for detached pieces, accidental openings, intersecting surfaces, and a base that will sit as intended. Review any geometry warnings shown by Kavi AI and your slicer. Automated checks are useful signals, but passing them does not prove the object will print successfully.
3. Check small features at the final size
Look closely at ears, fingers, tails, loops, and other narrow connections. Details that look substantial on screen can become fragile when the model is reduced. Minimum printable features depend on your printer, material, nozzle or resin process, and slicer settings; there is no single safe wall thickness for every setup.
4. Choose orientation and supports
Choose an orientation that gives the model stable contact with the build surface. Inspect overhangs and decide where supports are needed. Consider how support removal will affect visible surfaces and delicate details. A rounded figure may need different preparation from a flat-backed relief.
5. Review the sliced layers before printing
Slice with your actual printer and material profile. In the layer preview, check that important features remain present, that separate islands are supported, and that the base starts as expected. Review the material and time estimate. A small test print can help assess a design, but reducing its size also changes feature thickness and is not proof that the final version will work.
STL, 3MF, and GLB: which should you use?
STL is a widely supported geometry format for slicing. 3MF can carry units and additional model information, though what is present depends on the exporter and slicer. GLB is useful for displaying a textured model. None of these extensions alone guarantees a printable object or a multicolour print.
Prefer a print review?
Open the saved design in Kavi AI and request a printed copy. The studio reviews the model and provides a separate quote. Creating a digital model does not automatically place a print order or include manufacturing and shipping.
