Exploded android model print-prep visual

DEMO

Complete workflow: Auto-Slice + Exploded View

Upload a large model, rescale it, run geometric Auto Slice for your build plate, then inspect the separated parts in exploded view.

Core features — public pilot scope

Core workflows are available now; advanced and safety features are marked where they are still in progress.

Auto Slice to FitLIVE

Enter your printer dimensions and TooBig3D plans straight geometric plane cuts from the primary oversized axis, build volume, and margins. Review the resulting part dimensions before export.

AI Semantic Split

Optional higher-cost cloud AI finds natural part boundaries and completes hidden surfaces. Review results before applying; this action does not currently deduct 3DMe credits.

Alignment PegsLIVE

Dovetail, round, or square pegs with customizable tolerance, diameter, depth, and count for cleaner multipart assembly.

Part LabelingLIVE

Numbered labels are embossed on hidden connection surfaces so reassembly stays obvious even months later.

Mesh RepairLIVE

Auto-fix non-manifold edges, holes, and bad geometry before slicing scanned models or rough downloads.

Public Model Library SearchLIVE

Search Thingiverse, Printables, Thangs, and MyMiniFactory from inside TooBig3D, preview thumbnails, and start from a community model. Thingiverse supports direct import; Printables, Thangs, and MyMiniFactory open their source model pages for download.

Advanced Face SelectionLIVE

Box select, lasso, and brush selection let you cut or split exactly the geometry you need with precision.

Multi-Plate NestingLIVE

Auto-arrange parts across multiple build plates with 2D preview so you see the full print plan before export.

One-Click .3MF ExportLIVE

Export native 3MF files for Bambu Studio, Orca Slicer, and PrusaSlicer without conversion hassles.

Hollowing + Drain HolesLIVE

Hollow models to save material and add drain holes for resin or filament-saving workflows.

2 GB Public-Pilot ProcessingLIVE

Cloud-powered processing helps large files avoid browser crashes and freezes within the current 2 GiB public-pilot upload ceiling.

Ghost-Map HUDLIVE

A live wireframe mini-view shows the original model and tracks pieces as cuts are made.

Print Safety ChecksLIVE

Risk overlays, pre-export scorecards on supported export paths, and profile guardrails help catch failure points before you print.

Premium "Wow" Features

Premium tools for advanced print prep, including assembly documentation and stress analysis.

Ghost-Map HUD for original-vs-cut tracking
Assembly Manual PDF, Filament Budget Tracker, and Progress Bar 2.0
Puzzle Keys, Anatomical Auto-Slicing, Voice Director Mode, and Stress Simulator

Reliability & Safety

Safety and validation are first-class product features.

Print-Risk Hotspot Overlay highlights weak joints, thin walls, overhangs, bridging, tipping, and warping
Pre-Export Preflight Scorecard grades printability with mitigation suggestions
Pre-Print Safety Guardrails validate nozzle, bed, speed, cooling, and material profile choices

Everything in one platform

TooBig3D is not only a slicer page; the value is the complete oversized-model preparation workflow.

Import, repair, slice, hollow, label, peg, inspect, export, and assemble
Simple Mode for guided speed and Advanced Mode for precise control
Slicer handoff for Bambu Studio, Orca Slicer, PrusaSlicer, and Cura

Simple Mode vs Advanced Mode

TooBig3D adapts to how much control the maker wants, from guided AI speed to precision workspace tools.

Default

Simple Mode

For quick jobs, beginners, and hands-free prep. Describe the result, then let AI-guided actions handle the repetitive setup.

Natural-language and voice-first commands
Guided 3-step workflow from upload to export
Auto-slice, repair, pegs, labels, and hollow prompts
Best for fast model-to-print results

Power User

Advanced Mode

For complex models and pro workflows where exact cuts, selections, tolerances, and assembly details matter.

Manual cut planes, face selection, and seam control
Custom peg, label, hollowing, and alignment settings
Ghost view, command history, and fine-grained inspection
Best for precision and demanding assemblies

Switch anytime: start simple, then drop into Advanced Mode when the model needs exact cuts, tolerances, or assembly details — without restarting the workflow.

SIMPLE + ADVANCED MODES
● Simple Mode turns natural language into guided actions
● Advanced Mode keeps precision cutting, ghost view, face selection, and command history
● Switch modes instantly without losing the workflow
