Parametric 3D Models - True CAD for Functional Parts, Mesh When It Fits

SliceFoundry is a hybrid AI modeling platform for functional 3D printing. It analyzes each request - shape, dimensions, intended use, and features - then automatically routes the design to the right generation path: a custom true-CAD algorithm for precise, dimension-driven parts, or dedicated mesh generation for organic and visually complex geometry. You do not pick the workflow manually.

True Parametric CAD for Functional Parts

When the part needs real-world fit - brackets, enclosures, adapters, fixtures, tools, and other mechanical hardware - SliceFoundry builds it with a custom-built true CAD algorithm. That engine uses solid parametric CAD operations, not a game-style mesh dressed up as an STL:

• Dimension-driven sketches and solid modeling
• Extrusions, cuts, fillets, and chamfers
• Patterns, lofts, and boolean features
• Geometry organized around clearances, mounting points, and printability

The result is engineering-oriented solid geometry you can refine with follow-up prompts and export as STL for slicing, or as STEP, BREP, 3MF, AMF, SVG, and DXF when you need CAD-friendly or documentation workflows.

Mesh Generation When Organic Form Matters

Decorative, sculptural, and visually complex designs can use SliceFoundry's dedicated mesh generation path instead. That route is better when surface form matters more than parametric feature history - figurines, organic props, and similar shapes - while still targeting printable output.

Automatic Routing Between CAD and Mesh

1. Describe the part (or add a reference photo) with dimensions and intent.
2. SliceFoundry chooses the path - true parametric CAD, mesh generation, or a hybrid approach when both are appropriate.
3. Preview and refine with plain-language follow-ups until fit and structure are right.
4. Export individual pieces from multi-part designs and download the formats your workflow needs.

Functional prints stay on the custom CAD path so clearances and mounting geometry stay precise. Organic requests stay on mesh when that produces a better result. The platform decides; you focus on the part.

Why This Matters for Engineering-Grade Printing

• Not a render mesh with an STL button. Functional parts are constructed with true CAD operations around real dimensions.
• Automatic path selection. No separate "CAD mode" vs "mesh mode" for you to guess.
• Engineering exports. STEP and BREP when you need solids beyond a print mesh.
• Same toolbox. Pair generation with board-accurate enclosures, replacement parts, multi-part assemblies, and slicer profiles.

From Engineering-Grade Part to Perfect Print in One Platform

Most AI model generators stop at a decorative mesh. SliceFoundry goes further: once your engineering-grade part is ready, generate an optimized slicer profile for your exact printer and filament in the same session. If something goes wrong on the first print, Fix My Print diagnoses the failure from a photo and hands back a corrected profile. The whole workflow - design, slice, print, troubleshoot - lives in one place.

Prefer Hands-On CAD? Try Draftr

When you'd rather design a part precisely by hand than generate it from a prompt, Draftr is a desktop CAD application for Windows and macOS that combines AI with organic parametric CAD in an IDE-like workspace. It pairs a full parametric toolset - sketches, pads, pockets, fillets, chamfers, patterns, and threads - with natural-language AI commands, then exports print-ready STL files (and supports STEP-oriented CAD workflows). It's the natural next step once you outgrow prompt-based generation and want precise, editable, parametric models. Learn more at draftrcad.com.
