Why 3MS?

Why use the 3MS when there are many other multi-material systems?

Here are a few reasons:

  • Simplified Design: Minimal mechanical complexity for increased reliability.
  • Low Cost: A 4-filament-unit 3MS can be built for ~$150 USD
  • Easily Sourceable: All the parts for the 3MS are available on Amazon.
  • Comprehensive Documentation: Step-by-step guides to ensure smooth setup and operation.
  • Scalable: Easily expand the system to handle any number of filaments.

Requirements

To use the 3MS, your setup has to meet the following requirements:

  • Run Klipper firmware
  • Have SSH (PuTTY) access (99.9% of Klipper installations have this, and if you don't you really should setup SSH)
  • Have one spare USB port
  • Have an adapter to install a PTFE tube to the inlet of your printer's extruder.
