mcp-3D-printer-server

Overview

This MCP server provides a comprehensive interface to multiple 3D printer management systems including OctoPrint, Klipper, Duet, Repetier, Bambu Labs, Prusa Connect, and Creality. It enables advanced features like printer status monitoring, job control, temperature management, and sophisticated STL file manipulation including scaling, rotation, section editing, and base extension. The server supports slicing operations and can visualize 3D models through SVG generation. For Bambu printers, it offers direct .3mf file printing integration with MQTT commands and FULU OrcaSlicer-bambulab support.
