Recognize Character Structure & Split Automatically
Upload a character model and select a splitting template. Hi3D automatically detects the head, torso, arms, and legs, then separates them into individual parts with no manual cutting required.
AI-Powered3D Model Splitting
Detect model structure and split a 3D model into multiple parts in one click—making editing, assembly, and 3D printing easier.
How to Use Hi3D Smart Split
Complete model splitting, connector setup, and print preparation in just four simple steps.
From Model to Print with One-Click Smart Splitting
Automatically split, repair, and generate connectors for print-ready, assembly-ready parts.

From Model to Print with One-Click Smart Splitting
Automatically split, repair, and generate connectors for print-ready, assembly-ready parts.
Automatically Repair for Print-Ready Models
Every split part is automatically repaired and sealed to reduce broken surfaces, holes, and slicing errors, so it's ready to print without additional fixes.
Automatically Add Connectors for Easy Assembly
Generate pins, mortise & tenon, or ball joints with one click for stable assembly or articulated models with movable parts.
Fine-Tune Settings for Printing
Adjust the connector position, size, and type in Hi3D Studio, then export your model when it's ready for printing.
Any Model, Ready to Print & Assemble
Automatically split, repair, and generate connectors for print-ready, assembly-ready models.

FAQs About Splitting 3D Models for 3D Printing
Learn how to split a 3D model into parts, add connectors, prepare watertight parts, and get your model ready for 3D printing.
Hi3D works with character figurines, action figures, mechs, vehicles, and more. It can split a complete 3D model into the head, torso, limbs, weapons, base, or other individual parts for easier printing, multicolor printing, assembly, and articulation.
Yes. Upload your model and choose a processing mode or splitting template. Hi3D automatically detects its structure and splits it into parts without manual cutting, surface repair, or complex Boolean operations.
Yes. Hi3D automatically makes split parts closed and watertight to reduce holes, non-manifold geometry, and slicing errors. After adding connectors, export the parts and continue with layout, slicing, and printing.
Hi3D supports mortise-and-tenon joints, pins, plug-in connectors, and ball joints. Fixed connectors are ideal for figurines, vehicles, and display models, while ball joints work well for poseable characters, mechs, and action figures.
Yes. In Hi3D Studio, you can change connector type, position, orientation, and size, remove unnecessary connection points, and fine-tune them based on print size, tolerance, and assembly needs.
