What it does
MCP server that exposes FDM 3D-printing slicing, quoting, and design-for-manufacturability (DFM) analysis. Free tools run against 12 printer profiles and 12 filament materials with rate limiting; premium tools require x402 payment per call. Useful for anyone designing parts for 3D printing who wants accurate quotes, printability checks, and orientation optimization before committing to print.
- Check if a 3D model is printable on specific printer and material combinations, with support material and wall-thickness estimates.
- Get slicer-accurate print time, filament weight, and cost quotes with optional custom pricing parameters.
- Find the best model orientation to minimize support material usage by comparing multiple slices.
Tools this server exposes
| Tool | Does |
|---|---|
| list_printers | Returns the 12 available printer profiles with bed dimensions and nozzle size, 12 filament materials, and x402 pricing tiers. |
| check_printability | Analyzes model geometry for printability; free mode gives geometry preview, watertight check, wall-thickness estimate, and overhang heuristic; full mode returns |
| analyze_model | Returns geometry metadata: bounding box, volume, triangle count, watertight status, bed fit, and printable verdict. |
| get_print_quote | Generates slicer-accurate quote with print time, filament weight, and price; supports optional custom pricing inputs or FabTally hobbyist defaults. |
| optimize_orientation | Slices up to 4 model orientations and recommends the one requiring the least support material, showing exact savings (x402-metered). |
| slice_model | Produces full slice for any printer: layer count, time, filament; optionally returns preview PNG or G-code (x402-metered). |
Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
