3dprint-oracle is a 3D printing knowledge MCP server that gives LLMs authoritative access to 7,000+ filaments from 53 manufacturers across 33 material types, plus curated material science data — no API keys or network calls required at runtime.

• Search filaments: Search by name, material type, manufacturer, or color, with filtering by diameter and pagination support.

• Get filament details: Retrieve full specifications for a specific filament by ID or exact name, including temperatures, density, weight, colors, and manufacturer details.

• Browse manufacturers: List all 53 filament manufacturers with filament counts, optionally filtered by material type.

• Browse material types: List all 33 material types (PLA, PETG, ABS, TPU, Nylon, etc.) with filament counts and typical print settings.

• Get material profiles: Get a detailed material science profile including strength, flexibility, UV resistance, food safety, moisture sensitivity, difficulty level, typical uses, pros/cons, and nozzle requirements.

• Compare materials: Side-by-side comparison of 2–3 materials across all properties to help decide which material suits a project best.

• Recommend materials: Get ranked material recommendations based on project requirements such as strength, flexibility, heat resistance, food safety, outdoor use, ease of printing, and budget.

• Diagnose print issues: Troubleshoot 3D printing problems by symptom (e.g., stringing, warping, clogging), receiving ranked probable causes and material-specific fixes.
