Check whether a 3D model is printable before you slice it. The print check flags thin walls, steep overhangs and non-watertight geometry, and gives a print-readiness score.
Most failed prints can be predicted before slicing. Thin walls collapse, steep overhangs sag without support, and a mesh that is not watertight produces gaps in the slice. A print check catches these problems early.
TimrX's print check analyzes a model in the browser and reports the issues that matter for printing: wall thickness, overhang angles, non-manifold geometry and whether the surface is watertight. It returns a print-readiness score so you know at a glance if the model is ready.
Run the print check after generating or remeshing a model and before you export the STL. Fixing flagged issues first means fewer wasted prints, less filament and resin, and a cleaner result.
Generate a model in TimrX or upload a GLB, OBJ or STL you plan to print.
The check analyzes wall thickness, overhangs and watertight geometry, and returns a print-readiness score.
Remesh or adjust the model to clear flagged issues, then export a print-ready STL or 3MF for your slicer.
Confirm a model is printable before you commit filament, resin and machine time to it.
Verify that AI-generated meshes are watertight and thick enough before exporting them to a slicer.
Catch thin walls and fragile features on miniatures and detailed models before resin printing.
Make sure brackets, mounts and enclosures meet wall-thickness requirements for a strong print.
It analyzes wall thickness, overhang angles, non-manifold geometry and whether the mesh is watertight, then returns a print-readiness score summarizing how ready the model is to print.
Run the print check on TimrX. If walls are thick enough, overhangs are within a printable angle and the mesh is watertight, the model is ready. The readiness score gives you a quick verdict.
A watertight (manifold) mesh has no holes or gaps in its surface — every edge belongs to a closed solid. Slicers need watertight geometry to produce a correct print.
It depends on the printer and material, but very thin walls fail or do not print at all. The print check flags walls below a safe threshold so you can thicken them before printing.
Use the remesh tool to make the mesh watertight and even, thicken thin areas, or adjust the model, then run the check again before exporting.
Yes. The checks for wall thickness, overhangs and watertight geometry apply to both FDM and resin workflows.
The print check is part of the model workflow on TimrX, which runs on credits. New accounts get starter credits to try it. See the pricing page for current plans.
