Matt, All3DP's senior editor, is putting Creality's K3 toolchanger through its paces, and so far, the latest contender in the toolchanger arena has given him plenty of reasons to be optimistic. Naturally, that means it's time to make its life miserable. Enter a 78-hour multi-color print torture test.

Watch the latest dispatch from the All3DP Lab to see how Matt's getting on. The full review is coming soon.
