Two segmented android models shown assembled and exploded into printable parts

From impossible to printable.Browser-based prep with AI-assisted suggestions and manual control.

Import

Bring in any STL, OBJ, or 3MF model.

AI Process

AI-assisted analysis with cut and assembly suggestions you review and confirm.

Organize

Parts are arranged, labeled, and prepared for printing.

Print & Assemble

Print with confidence and bring your model to life.

Everything you need. AI when it helps.

Two Split Modes

Use straight geometric cuts for predictable build-plate planning, or choose the optional higher-cost AI Semantic Split for natural part boundaries and completed hidden surfaces.

Mesh Repair

Suggests repairs for holes, manifold issues, and other mesh errors—review and apply manually.

Auto Alignment

Creates precision pins, holes, and interlocks for perfect assembly.

Print Prepared

Optimized orientation, nesting, and support-aware output.

Assembly Ready

Labeled parts, guides, and instructions make assembly simple.

Model Library Search

Browse Thingiverse, Printables, Thangs, and MyMiniFactory, preview thumbnails, and start from a community model.

Why makers switch to TooBig3D.Keep the original promise: less CAD pain, more printable parts.

Plain-English print prep

Tell TooBig3D what you need — slice this helmet, add alignment, label parts, repair the mesh — and keep moving instead of rebuilding the workflow by hand.

Large models without desktop crashes

Browser-based cloud processing is built for oversized files and multipart exports, so makers are not trapped by aging desktop utilities or local memory limits.

Assembly planned from the start

Cuts, pegs, labels, exploded views, and slicer-ready exports are treated as one workflow instead of disconnected chores.

Two workflow modes: simple when you need speed, advanced when you need control.

Simple Mode

Use AI-guided defaults and natural-language commands when you want to get from model to printable parts quickly.

Fast guided actions
Build-plate aware auto-slicing
Repair, labels, and export prompts

Advanced Mode

Drop into precision tools when the model needs surgical control over cuts, seams, face selections, pegs, labels, and inspection.

Manual cut and selection controls
Ghost view and command history
Fine-grained assembly prep

Safe & Secure — Unlike Sketchy Desktop Apps.No random installers. No mystery workflow. Your slicer still stays in the loop.

Browser-based

No sketchy desktop download required. Sign in, upload, prepare, export, and delete files from your account when you need to.

Private by default

Private uploads are not used to train public AI models by default. Retention by plan: Free 7 days, Hobbyist 30 days, Maker Pro 90 days, Lifetime 365 days, with manual delete controls.
