Why is my 3D print stringing?

Stringing is usually caused by under-retraction or a print temperature higher than the filament needs. SliceFoundry's troubleshooter analyses your photo and slicer settings to recommend a specific retraction distance, retraction speed, and temperature change.

What causes layer shifts mid-print?

Layer shifts are mechanical: a loose belt, missed steps from too-high acceleration, or an obstruction the print head hit. The troubleshooter helps narrow it down to belt tension, acceleration limits, or print speed depending on the failure pattern.

How do I fix bed adhesion problems?

Bed adhesion problems usually trace back to nozzle height, bed temperature, surface preparation, or first-layer flow. The troubleshooter looks at your description and photo to identify which one is most likely and what to change.

3D Print Troubleshooter — Diagnose a Failed Print, Fast

SliceFoundry's 3D print troubleshooter diagnoses failed prints by analysing a photo and your description of what went wrong. The AI identifies the most likely cause, explains why it happens, and recommends concrete slicer setting changes you can apply right away.

Better than scrolling through generic checklists — the troubleshooter actually looks at your specific failure and matches it to the right fix.

Common 3D Print Failures the Troubleshooter Handles

Stringing — fine wisps of plastic between separated parts; usually a retraction or temperature problem.
Layer shifts — sudden horizontal offsets mid-print; mechanical, belt, or acceleration related.
Warping — corners lifting from the bed; adhesion, cooling, or material specific.
Under-extrusion — gaps, weak walls, missing top layers; flow, temperature, or nozzle issues.
Over-extrusion — blobs, dimensional growth, ringing artifacts.
Elephant's foot — first layer wider than the rest.
Z-banding — visible horizontal ridges from Z-axis irregularities.
Stringy or rough overhangs — cooling and bridging tuning.
Failed bed adhesion — first layer detaches mid-print.
Spaghetti prints — model detaches and the nozzle keeps extruding into air.

How the Troubleshooter Works

Upload a photo of the failed print. Multiple angles help, especially close-ups of the worst region.
Describe what you saw — when the print failed, what happened, what you'd tried already.
Attach your slicer settings (optional) — paste in the relevant Cura, OrcaSlicer, PrusaSlicer, or Bambu Studio export and the AI will reason about them directly.
Read the diagnosis — root cause, why it happens, and what to change.
Apply the fix — either copy the suggested settings into your slicer or generate a fully corrected SliceFoundry profile in one click.

What Makes a Good Diagnosis Submission

Clear, well-lit photos. Close-ups beat one overall shot.
The filament brand and material (PLA, PETG, ABS, TPU, PLA+).
Your printer model and nozzle size.
Whether the failure was on the first layer, in the middle, or near the top.
Any recent changes — new filament spool, new nozzle, new slicer version.

After the Diagnosis

Once you know the cause, you can either tweak your existing slicer settings or use SliceFoundry's profile generator to spit out a corrected profile for your specific printer and filament. Either way, the next print should land closer to what you wanted the first one to be.
