Public answers for makers evaluating TooBig3D — workflow, slicer compatibility, pricing, privacy, AI, exports, and premium tools.
Public answers for workflow, slicers, credits, subscriptions, AI, retention, file limits, premium tools, and print responsibility.
Those slicers are excellent at converting a print-ready model into G-code. TooBig3D handles the prep step before that: splitting oversized models, adding alignment pegs, labeling parts, repairing mesh issues, planning seams, and exporting organized files that your slicer can open.
TooBig3D exports standard STL and 3MF-style workflows that open in Bambu Studio, Orca Slicer, PrusaSlicer, Cura, and other slicers that accept STL or 3MF files. Multi-part exports are organized so you can keep using the slicer you already trust.
No. TooBig3D is browser-based — no desktop installer, no admin rights, no driver setup, and no background service on your computer. Upload a mesh, prepare it in the web app, then download print-ready parts for your slicer.
No software can guarantee a print. TooBig3D helps catch common issues and prepare cleaner exports, but you still need to review slicer previews, material settings, supports, temperatures, bed adhesion, and printer limits before sending a job.
Credits are spent on model operations that use our compute pipeline. Slicing a 3D model spends one credit. AI generation also spends credits (most text-to-3D and image-to-3D runs cost 1 credit; high-quality runs cost 3 and texture refines cost 2). Uploading, previewing, and transforming models is always free — credits are only spent when you actually run a slice or AI generation.
Yes. Cancel anytime and keep paid features through the end of your billing cycle. After that, your account automatically returns to Free.
Free includes enough credits and core features to test your real workflow before paying. Once you need higher throughput or premium tools, Hobbyist, Maker Pro, and Lifetime provide clear upgrade paths without hidden fees.
We cap free usage with account-level credits and operational limits, then enforce billing controls on paid upgrades. That combination keeps trial access fair while reducing repeat-account abuse and protecting capacity for paying users.
Yes — Maker Pro is available monthly or annually (annual is shown with the billing toggle), and we also offer one-time options (Hobbyist and Lifetime).
We support STL, OBJ, PLY, and 3MF files. Export is available in STL format and as a ZIP bundle for multi-part models.
Free: up to 1 GB/file. Hobbyist, Maker Pro, and Lifetime: up to 2 GB/file during the public pilot. Higher tiers add credits, retention, storage, and premium workflow features.
Yes. Maker Pro includes monthly credits with rollover for up to 2 months as long as your subscription stays active. Hobbyist credits are one-time and never expire.
We accept all major credit cards (Visa, Mastercard, American Express) through our secure payment processor, Stripe.
AI powers natural language commands and smart suggestions. Uploaded meshes and AI-generated outputs (text-to-3D and image-to-3D) share the same retention by plan: Free 7 days, Hobbyist 30 days, Maker Pro 90 days, Lifetime 365 days. Expired files are permanently purged within 24 hours. Private uploads are not used to train public models by default; no public model-training opt-in control is available in the current implementation.
Retention by plan: Free 7 days, Hobbyist 30 days, Maker Pro 90 days, Lifetime 365 days. After your window ends, files are queued for deletion and permanently purged within 24 hours.
AI-generated outputs (text-to-3D and image-to-3D models produced inside TooBig3D) follow the same per-plan retention windows as uploaded meshes: Free 7 days, Hobbyist 30 days, Maker Pro 90 days, Lifetime 365 days, then purge on the same 24-hour cycle. Re-export the result locally if you want to keep it beyond your plan window.
After your retention window ends, files are queued for deletion and permanently purged within 24 hours. You can also delete any file manually at any time from your dashboard.
Private uploads are not used to train public models by default. No model-improvement opt-in control is available in the current implementation.
No! AI is completely optional. All features work without AI — you can slice, add pegs, export, etc. through the normal interface. AI just makes some tasks faster with natural language commands like “slice into 3 parts.”
All plans include: Natural language commands (“make it hollow”), AI help assistant (context-aware Q&A), Smart cut suggestions (geometry analysis), and Print settings advisor (material-specific recommendations).
Wow features are premium tools for advanced print prep: Ghost-Map HUD (live wireframe mini-view), Assembly Manual PDF (auto-generated instructions), Puzzle Keys (LEGO-style connectors), Anatomical Cut Suggestions (Beta, geometry-based suggestions you review before applying), Voice Director Mode (hands-free commands, Beta - browser-dependent), and Stress Simulator (heat map visualization).
Puzzle Keys are unique asymmetric connectors (like LEGO bricks) that only fit one way. Each connection has a distinct shape, which helps parts assemble the intended way. Useful for complex multi-part prints.
Auto-generated instructions like IKEA manuals! Includes: cover page with part count, numbered parts list with thumbnails, step-by-step visual assembly guide, connection close-ups, and material-specific tips. Print it or share digitally.
Speak commands naturally: “Slice this helmet for my X1 Carbon with puzzle keys” — the AI understands and executes multi-step operations. It uses the browser Web Speech API, so it requires a supported browser (Chrome, Edge, Safari). In unsupported browsers, the microphone button hides itself and typed commands work normally. It knows your saved printer profiles and can combine multiple actions in one command.
Simple Mode uses AI-assisted commands -- describe what you want and review the AI suggestions before applying. Advanced Mode gives full manual control with tabbed interfaces for precise workflow management. Switch between modes instantly -- your project stays open in both.
