BMCU-AMS

🌟 BMCU-AMS: The DIY Multi-Color Material System for your 3D Printer 🌟

Brief Description

The BMCU-AMS is a modular, self-printed filament management system, inspired by the Bambu Lab AMS. It was developed to provide a reliable and cost-effective way to achieve multi-material and multi-color prints. Use existing BMCU units (with 4 inputs) and 3D printed parts to build a clean, organized, and fully functional material station

NOTE: This project is a framework for your own BMCU electronics, designed for 4 filament spools. It is a DIY project and not an official Bambu Lab component

Main Features (Your Added Value for the Community)

• 4-Color/Material Capability: Supports four BMCU units for an automated multi-color experience
• Smooth Filament Guide: The integrated spool holder is equipped with 16 608zz ball bearings to ensure extremely smooth and low-friction filament feeding
• Modular & Stable: The BASE construction provides a stable stand and a clean look for integrating your electronics
• Clean Cable Management: The mounts and base are designed so that the BMCU board cables are routed invisibly
• Optimized Design: All parts are designed for a perfect fit (light post-processing of edges may be necessary) and easy assembly (screwed components)

Required Components (In Addition to 3D Printing)

• Electronics: 4x BMCU Unit (with 4 inputs)
• Bearings: 16x 608zz Ball Bearings
• Screws & Inserts: Various M3 and M4 screws, as well as M3 and M4 heat-set inserts (details in the assembly instructions)
• Optional: Pneumatic connectors and PTFE tube
• Optional: Cable extensions (soldering or new cables) for the BMCU board

Print Settings & Assembly

Print all parts with the recommended settings (PLA or PETG, 2-3 perimeters, 15-20% infill). The detailed, illustrated assembly instructions can be found as a PDF in the download section
