Bambu Lab 3d printers produce really clean multi-material results. However, due to a filament cutting system that prioritises reliability, there can be an excessive amount of filament and time wasted. In this video, I explore some options for clawing some efficiency back. The gains aren’t huge, but are still worthwhile.

Thanks to my patron David who inspired this video during a great discussion.
