3dprint Oracle tools (8)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • compare_materials

    Compare 2-3 material types side by side across all properties: strength, flexibility, heat resistance, food safety, print difficulty, and more. Useful for deciding which material to use for a project.

  • diagnose_print_issue

    Diagnose a 3D printing problem by symptom. Returns possible causes ranked by probability, with specific fixes for each. Optionally filter by material type for material-specific troubleshooting.

  • get_filament

    Get detailed information about a specific filament by ID or exact name. Returns full specs: temperatures, density, weight, colors, and manufacturer details.

  • get_material_profile

    Get a detailed material science profile for a specific material type. Includes strength, flexibility, UV resistance, food safety, moisture sensitivity, difficulty level, typical uses, pros/cons, and nozzle requirements.

  • list_manufacturers

    List all filament manufacturers in the database, with filament counts. Optionally filter to manufacturers that produce a specific material type.

  • list_materials

    List all material types available in the database (PLA, PETG, ABS, TPU, Nylon, etc.) with filament counts and typical print settings. No inputs required.

  • recommend_material

    Recommend the best 3D printing material based on project requirements. Describe what you need (strength, flexibility, heat resistance, food safety, outdoor use, ease of printing, budget) and get ranked material suggestions with explanations.

  • search_filaments

    Search 7,000+ 3D printing filaments by name, material type, manufacturer, or color. Returns filament specs including print temperatures, density, and available colors.

Install 3dprint Oracle in Claude Code, Cursor or VS Code

Runs npx -y 3dprint-oracle on your machine. Read the scan report first; the gateway never runs local packages.
