MCP 3D Printer Server

What it does

This server provides a comprehensive bridge between AI agents and 3D printer management systems. It allows for real-time status monitoring, file management, and direct print control across a wide variety of hardware ecosystems.

Tools

• get_printer_status: Retrieves current temperatures and print progress.
• list_printer_files: Lists G-code files available on the printer.
• upload_gcode: Uploads and optionally starts a G-code print.
• print_3mf: Specifically for Bambu printers, handles .3mf uploads and MQTT print commands.
• scale_stl / rotate_stl / translate_stl: Performs geometric manipulations on STL models.
• slice_stl: Converts STL files to G-code using configured slicers like PrusaSlicer or OrcaSlicer.
• generate_stl_visualization: Creates SVG previews of 3D models from multiple angles.
