# Upcoming Challenge: November 2026

## Challenge: Multi-Material Printing

Explore the boundaries of multi-color and multi-material additive manufacturing! Whether you use an AMS, MMU, toolchanger, IDEX, manual filament swapping, or dual extrusion, show off what is possible when combining colors and materials in a single print.

### The Focus: Multi-Color & Multi-Material Mastery

The goal is to showcase prints that utilize more than one material or color:
- **Multi-Color Aesthetic Models**: HueForge paintings, color-separated figurines, badges, and decorative art.
- **Multi-Material Functional Prints**: Rigid bodies with TPU flexible gaskets/grips, dissolvable/PETG support interfaces for flawless overhangs, or contrasting text inserts.
- **Manual Layer Swaps**: Single-extruder layer-pause color swaps for signage and high-contrast designs.

### Submission Requirements

* **Physical Model**: Bring your multi-material/multi-color print to the **November 18th, 2026** meetup.
* **Open to All Setups**: Automated filament systems (Bambu AMS, Prusa MMU, Voron StealthBurner ERCF, Snapmaker), multi-toolheads, or manual pause-at-layer color changes all qualify!
* **The Story**: Share your workflow, slicer tips (purge tower optimization, flush volumes, interface materials), and how you dialed in your print.

### Judging & Prize

* **Voting**: Community members present at the November meetup will vote on favorite prints based on execution, color design, and technical mastery.
* **Prize**: The winner will receive a **free spool of filament**!

### Timeline

* **Challenge Announcement**: October 28th, 2026 (at the October meetup)
* **Show & Tell / Voting**: November 18th, 2026 (during the November meetup)
* **Winner Announcement**: November 18th, 2026 (end of the November meetup)
