AI 3D Model Segmentation

Split any 3D model into clean, separate parts with AI. Upload a mesh or STL file and our 3D model segmentation engine automatically detects and separates components into individually editable parts

Automatic 3D Model Segmentation

AI analyzes mesh geometry to detect natural boundaries and segment a 3D model into meaningful parts automatically. No manual edge selection, no tedious loop cutting — upload a model and the 3D model segmentation engine separates it into clean, independent components in seconds.

Split a 3D Model into Editable Parts

Every detected component is exported as a separate, watertight part you can move, edit, retexture, or delete on its own. Split a 3D model into parts for modular editing, then reassemble or animate each piece independently in Blender, Maya, or any DCC tool. AI part completion seals any open geometry so each part stays manifold.

Mesh & STL Segmentation

Works as a full mesh segmentation tool and 3D model splitter across formats. Bring in FBX, GLB, OBJ, or STL, segment the mesh into parts, and export each component back to STL or your preferred format — ideal for both digital editing and 3D printing.

How 3D Model Segmentation Works

Upload a model, let AI segment it, and download separated parts in minutes — no manual selection or 3D modeling experience needed.

1

Upload Your 3D Model or STL

Drag in any 3D model — FBX, GLB, OBJ, or STL. Use a model you generated here or import an existing mesh you want to split into parts.

2

AI Detects & Segments Parts

The 3D model segmentation engine analyzes the mesh, identifies component boundaries, and separates the model into independent parts. Optional part completion seals any open geometry so each piece stays watertight.

3

Preview & Download Separated Parts

Inspect every detected part in the 3D viewer, then export the segmented model — keep all parts together or download each component separately as STL, FBX, or GLB for editing, rigging, or 3D printing.

Why Use AI for 3D Model Segmentation

Manual splitting means hours of edge loops, separate-by-loose-parts guesswork, and broken geometry. AI 3D model segmentation does it in seconds.

Fully Automatic

No manual selection or edge marking. AI detects component boundaries and segments the mesh for you, even on dense, high-poly models.

Watertight Separate Parts

Optional part completion rebuilds missing surfaces so every component is closed, manifold, and ready for editing or printing.

Multi-Format Support

Import and export FBX, GLB, OBJ, and STL. Segment once and take your separated parts into any DCC tool, game engine, or slicer.

Runs in Your Browser

No plugins, no installs. Upload, segment, and download separated parts entirely online from any device.

What You Can Do After Splitting a 3D Model into Parts

From game asset editing to 3D printing, separating a model into independent parts unlocks workflows that a single fused mesh simply can't support.

  • Edit & Remodel Parts Separately

    Segment a 3D model into parts to tweak, retexture, or replace one component without touching the rest. Perfect for fixing AI-generated models, swapping accessories, or remodeling a single section of a complex mesh.

  • Rigging & Animation

    Separate a 3D model into parts so each limb, joint, or moving piece can be rigged and animated independently. Clean part boundaries make weight painting and auto-rigging far faster and more predictable.

  • Split STL into Parts for 3D Printing

    Split an STL into parts to print oversized models on a small bed, separate multi-color components, or break a 3D model into pieces that assemble after printing. Every exported part is watertight and slicer-ready.

  • Modular Game & 3D Assets

    Cut a 3D model into pieces to build modular, reusable game assets. Detach weapons, armor, props, or character parts as separate meshes for LODs, customization systems, and faster iteration.

User Reviews

Trusted by 3D Artists, Game Devs, and Makers

Modelers, animators, and 3D printing enthusiasts use our 3D model segmentation tool to split and separate models into parts.

    I used to spend an hour separating AI-generated characters by hand. Now I upload the model, segment it, and every limb comes out as a clean, watertight part ready to rig. It cut my prep time to minutes.

  • 4.9

    Splitting an STL into parts for my printer used to mean fighting with cut tools. This segments the model into print-ready pieces automatically, and the parts actually stay watertight in the slicer.

    Megan Liu, 3D Printing Enthusiast

  • 5.0

    We build modular game assets, so being able to cut a 3D model into separate parts on the fly is huge. The component boundaries are surprisingly clean, even on dense meshes.
