Bambu Lab dropped a bombshell announcement just one hour after the release of its newest 3D printer, the H2S. The company revealed the H2C, a tool changer-like system that it says will hit the shelves before Christmas.
The H2C promises to tackle the problem that plagues every Bambu Lab 3D printer with an AMS: printer poop. This “poop” is the waste purged from the nozzle as it is cleaned between color changes. Most color systems for 3D printers have multiple spools connected to one tool head, with one shared nozzle. Because it’s impossible to remove all the melted plastic from a hot nozzle, a certain amount is pushed through the nozzle as waste.
Prusa Research’s MMU system minimizes waste by yanking back the majority of the old color. The other option is a tool changer, like Prusa Research’s XL or the Snapmaker U1. Tool changers solve the problem by having multiple tool heads, with one for every color.

Bambu Lab proposes a new system, similar to a tool changer, that swaps only the nozzle. This system builds on the easily swappable nozzle design introduced with the A1 and carried over to the H2D and H2S. These machines use nozzles that are attached magnetically, and already uses thermal induction to heat up. All that was left was figuring out how to remove the wires needed for the thermistor, which regulates the temperature.
