BigTreeTech ViViD: Open-Source AMS for Klipper Printers

What Is ViViD?

BigTreeTech has launched the ViViD, an open-source multi-material filament changer designed to bring Bambu Lab-style multi-color printing to Klipper-based 3D printers. Priced around $320, it offers an alternative to proprietary systems like the Bambu AMS.

Key Features

The ViViD combines a multi-material unit with a built-in dryer box — addressing two needs at once. Key specifications include:

• Open-source design — Files available for modification and community improvement
• Klipper compatibility — Works with the most popular firmware for advanced printers
• Integrated dryer — Keeps filament dry during long multi-color prints
• Automated filament changing — Handles the swap between colors automatically

The Market Gap It Fills

Bambu Lab's AMS is excellent, but it only works with Bambu printers. For users of Voron, Creality K1, Elegoo Neptune, or any other Klipper-based machine, multi-color printing has required either manual filament swaps or complex custom setups.

The ViViD targets this gap directly. It brings the convenience of automated multi-material printing to the broader Klipper ecosystem — a community that has largely built its own solutions or gone without.

Competition

The ViViD isn't alone in this space. The LDO BoxTurtle is another open-source option at around $299, targeting similar users. Both systems recognize that Klipper users want multi-color printing without switching to a Bambu ecosystem.

Where ViViD differentiates is its integrated dryer box — a practical feature for long prints where moisture can ruin filament mid-job.

What This Means

The open-source multi-material ecosystem is maturing. Users no longer need to choose between Bambu's walled garden and single-color printing. The ViViD and competitors like BoxTurtle are bringing AMS-style convenience to the broader 3D printing community.

For BigTreeTech, known for mainboards and electronics, this represents a move into mechanical systems — and a play for the Klipper community that has driven much of the innovation in desktop 3D printing over the past few years.
