3DMold - 3D Mold Maker & STL
Split CAD Models for Printing
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
3DMold is a professional-grade automation tool that bridges the gap between 3D design and physical production. Designed for industrial designers, engineers, and advanced makers, it converts complex STL files into precision-aligned, ready-to-print industrial molds directly from your iPhone or iPad.
Leveraging the industry-standard OpenCASCADE geometry kernel and high-performance GPU cloud cluster, 3DMold handles high-poly models with surgical precision, ensuring your physical parts fit perfectly every time.
Supports deep integration with AI Agents and Apple Shortcuts, allowing you to generate industrial-grade molds via simple voice commands or external AI tools like OpenClaw and ChatGPT.
Key Features:
- Intelligent Parting Sweep: Benefit from a full-auto engine that sweeps across all axes and offsets to find the globally optimal split position with the lowest undercut risk.
- Smart Core-Cavity Mode: Beyond simple splitting, 3DMold automatically identifies internal volumes and exterior shells to extract matching Cores and Cavities.
- Industrial Alignment Pin System: Integrated alignment pins ensure perfect mold registration. Customize "Clearance", "Draft Angle", and "Chamfer" for an industrial-grade fit without extra hardware.
- Automated Runner & Vent: Automatically generate injection gates and venting channels to optimize resin flow and escape air during casting.
- Precision Engineering: Achieve up to 0.1mm tolerance—the industry standard for high-resolution 3D printing (SLA/DLP/FDM) and precision fitment.
- Shrinkage Compensation: Compensate for material-specific cooling shrinkage with surgical precision, ensuring the final cast parts remain true to original dimensions.
- Advanced Pry Slots: Integrated asymmetric lever slots allow for effortless mold separation using standard tools, protecting delicate internal features.
- Real-Time Undercut Visualizer: Inspect your model in a full 3D workspace with real-time feedback on "Undercut Ratio" and "Interlock Risk".
- Advanced Mesh Optimization: Built-in "Model Lightweighting" and "Auto Cleanup" remove isolated slivers and islands.
- Zero-Trace Privacy: Models are scrubbed from servers immediately after download. Your intellectual property is protected.
