ask the nozzle
The most advanced 3D-printing AI

One AI. Three tools.
Built for real prints.

Ask anything. Pre-flight your gcode. Diagnose what went wrong. All powered by a vision-enabled AI trained on a curated database of real-world 3D-printing cases.

Step 1 · Open-ended

Ask

Conversational expert advice on anything 3D-printing — material choice, calibration plans, settings tuning, comparisons, design tradeoffs. Optional photo or gcode.

From 6 credits Open
Step 2 · Rule-based

Pre-flight

Drop your gcode before you press print. Rule-based engine catches known-bad slicer-setting combinations — brass nozzle on abrasive material, PETG bed too cold, layer too thick for nozzle.

Step 3 · Vision AI

Diagnose

Print failed? Upload photos and gcode. The AI identifies the defect from the photos, cross-references the knowledge base, and recommends concrete slicer setting changes you can download for any major slicer.

Why this is the most advanced 3D-printing AI

What sets Ask The Nozzle apart from generic chatbots and rule-only lint tools.

Vision AI on your actual photos

Most "AI" 3D tools only read settings. We look at the print — identifying additive vs subtractive surface defects, distinguishing wet filament from nozzle drag, reading what your eyes see.

Curated knowledge base

Distilled from hundreds of community, vendor, and academic sources and thousands of real-world test cases — continuously reviewed and refined. Real-world, not hallucinated.

Conversational follow-ups

Most diagnosis tools are one-shot. Tried our suggested fix? Send a new photo. Got worse? Tell us. Every case becomes a thread that learns as you iterate.

Actionable setting recommendations

Every diagnosis lands as a clean list of concrete setting changes — exact key, current value, recommended value, and a one-line reason for each. PrusaSlicer / OrcaSlicer users can also download an importable .ini patch.

Pre-flight rule engine

Drop your gcode and instantly catch the most common slicer-setting mistakes before you waste a print. 22 deterministic rules covering material/nozzle compatibility, volumetric flow, temperatures, cooling, adhesion and more — for one credit.

Honest data handling

Default: we keep no record of your submission — only an anonymous count for billing. Opt in to help train the agent, and you can delete any case any time by ID.
