Smart Splitting
Break a model into sections that suit your printer. Consider where each cut falls so small details and delicate parts stay in mind.

Powerful Features
A practical way to think through large-model printing
Alignment Planning
Think about how the pieces will meet after printing. Leave room in your plan for registration, joining and a clean final assembly.
Model Preview
Inspect the shape and imagine the cut lines before committing to a print. A clear view helps you choose sensible sections.
Simple Workflow
Start with the model you want to print, decide how it should be divided, and continue to the online STL tool for the next step.
Flexible Decisions
Let build volume, model geometry and assembly needs guide the size and placement of your printable pieces.
Project Checklist
Keep track of the practical details: printable dimensions, the number of parts and how the finished model goes back together.
How It Works
Get started in 3 simple steps
1
Upload STL File
Bring your large STL model to the online tool. First, check its overall size against your printer’s build volume.
2
Plan Your Sections
Choose a practical way to divide the model. Consider print orientation, seams and how the pieces will be assembled.
3
Export & Print
Continue with the tool’s available export steps, then prepare the resulting parts in your preferred printing workflow.
Built with Modern Technology
Large-model printing brings together digital geometry, careful planning and dependable tools. These are the ideas behind the workflow.
- 3D mesh geometry — Understand the shape before placing cuts
- Build-volume planning — Size parts for the printer you use
- Model inspection — Review seams before you print
// Plan a printable model
const project = {
model: 'large-sculpture.stl',
checkBuildVolume: true,
reviewSeams: true,
planAssembly: true
};
// Review each part before printing
for (const part of plannedSections) {
checkDimensions(part);
inspectJoiningFaces(part);
