Quick answer: Auto Split takes a Meshy model and cuts it into separate, watertight parts sized to fit your build plate — ready to export straight to your slicer. It works on Standard, untextured (draft) models generated with Meshy 6. A full split previews in about 40 seconds, and you can re-split as many times as you like before committing.
What is Auto Split?
In Meshy, Auto Split is a one-click feature that breaks a 3D model into printable parts. Instead of manually cutting a model in Blender or a slicer and repairing the holes that creates, Auto Split finds the model's natural structural boundaries — like where a neck meets a torso, or a wing meets a body — cuts along them, and automatically caps every cut surface so the parts come out watertight and ready to print.
How Auto Split Works
Fast preview — the full split renders in about 40 seconds, and what you see is the same geometry you'll export, not a placeholder.
Smart cuts — boundaries follow the model's geometry instead of arbitrary planes, and parts are sized to fit a standard build plate.
Watertight parts — every cut surface is automatically capped into a closed mesh, so parts are ready to slice without manual repair.
Re-split anytime — if the first result isn't what you wanted, you can re-run Auto Split. Re-splitting doesn't destroy your original draft.
You can refer to the tutorials article to know more details about the feature.
How many credits does Auto Split cost?
Each Auto Split generation costs 10 credits. If you'd like to retry a generation, keep in mind that each attempt will also consume 10 credits.
FAQ
1. Can Auto Split handle textured models?
Not yet. Auto Split currently works only on Standard, untextured (draft) models generated with Meshy 6. Support for textured models is planned but not available today.
2. Do I need to repair the parts before slicing?
No. Every cut is automatically capped into a watertight mesh, so you can send parts straight to Bambu Studio, OrcaSlicer, or ElegooSlicer without extra repair steps in Blender or Meshmixer.
3. Can I change the split if I don't like the result?
Yes. Auto Split is non-destructive, so you can re-run it as many times as you like. Each attempt takes about 40 seconds.
4. Does Auto Split work with Low Poly models?
No. Auto Split only appears for Standard model type generations on Meshy 6 — it isn't available for Low Poly or other model types.
