01
Upload Your Model
Upload a supported file such as GLB, STL, or OBJ. Use a figurine, miniature, toy, prop, sculpture, prototype, or other model that needs to be divided for printing.
3D Segmentation
AI 3D Model Splitter
Split 3D models into clean printable parts with AI. Upload your model, choose how it should be divided, and create separate components for easier printing, painting, and assembly.
Character and General Split Modes
Choose the right splitting method based on the type of model you want to print.
Character Mode
Character mode is designed for humanoid models, figurines, toys, miniatures, and creatures. It identifies common body areas and creates practical part layouts for printing, painting, and assembly.
General Mode
General mode works with props, sculptures, decorative objects, prototypes, product concepts, and other non-character models that need to be divided into printable sections.
Smart Joint Options for Assembly
Choose how the separated parts should connect after printing.
No Joint
Use no joint when you need separate parts for independent printing, painting, positioning, or manual assembly.
Ball Joint
Use ball joints for poseable or attachable character parts, including heads, arms, legs, tails, and accessories.
Dovetail Joint
Use dovetail joints for stable sliding connections on props, hard-surface objects, display models, prototypes, and larger printable parts.
Three steps
How to Split a 3D Model Into Parts
Turn one complete 3D model into separate printable parts in three simple steps.
02
Choose Split Mode and Parts
Choose Character mode for humanoid or figure-style models, or General mode for props, sculptures, products, and other objects. Divide the model based on its shape, printer build volume, painting plan, and intended assembly.
03
Add Joints and Export
Choose no joint, ball joint, or dovetail joint depending on how the parts should connect. Inspect each component and export the separated model for printing and assembly.
Made for Easier Printing
Built for 3D Model Splitting and Printing
Divide complex models into practical parts that are easier to print, paint, fit together, and assemble.
01
Miniatures & Figurines
Separate heads, torsos, arms, legs, weapons, accessories, and bases for easier printing, painting, and assembly.
02
Toys & Collectibles
Split toys and collectible models into separate components and add joints for fixed or poseable assembly.
03
Props & Decorations
Divide masks, sculptures, ornaments, signs, and larger props into manageable sections that fit your printer’s build volume.
04
Prototypes & Custom Models
Break prototypes and custom product models into modular components for separate printing, testing, and assembly.
Loved by 3D Printing Creators Around the World.
Used by makers, miniature artists, product designers, model sellers, and print studios to turn ideas into physical creations faster.
“Crisp3D helps me turn character ideas into detailed models much faster. I can explore several variations before choosing the best one for resin printing.”
Ethan Blake
Resin Miniature Artist
“I can turn a sketch into a 3D model, split complex designs into parts, and prepare everything for slicing without switching between multiple tools.”
Lena Morris
3D Printing Hobbyist
“Crisp3D makes it much easier to turn early concepts into physical prototypes. I can test different shapes and ideas before committing time and material to a print.”
Maya Chen
Product Prototype Designer
“The segmentation tools make large figures much easier to print, paint, and assemble. Being able to add practical joints in the same workflow saves me a lot of time.”
Daniel Rivera
Collectible Model Creator
“Using different AI models and sending the result directly to my slicer makes custom projects much faster, especially during busy production periods.”
Noah Williams
3D Print Shop Owner
“I use Crisp3D to turn reference images into prop concepts, split large models to fit my printer, and prepare the parts for printing and assembly.”

FAQ
Frequently Asked Questions
What is a 3D model splitter?
A 3D model splitter divides one complete model into separate components. This can make large or complex models easier to print, paint, fit together, and assemble.
Can I use it for non-character objects?
Yes. General mode can split props, sculptures, decorations, prototypes, product concepts, and other non-character models into practical printable sections.
Is model splitting useful for 3D printing?
Yes. Splitting can help large models fit within the printer’s build volume and make individual parts easier to orient, support, print, paint, and assemble.
Can I add joints to split parts?
Yes. Choose no joint, ball joint, or dovetail joint depending on whether the parts should remain separate, slide together, or support fixed or poseable assembly.
What file formats can I upload?
Crisp3D supports common 3D formats including GLB, STL, and OBJ for model splitting and preparation.
Can I split character models?
Yes. Character mode is designed to separate humanoid models, figurines, toys, miniatures, and creatures into logical body parts.
Are the split parts ready to print?
Split parts may still require final checks based on your printer and material. Inspect scale, wall thickness, joint tolerances, orientation, supports, and other print settings before printing.
