Bambu Lab printers build colossal replica in six-day race
Six days to build a giant
It sounded like a wild handyman's dare. The challenge was to build a 3D printer so massive that people could actually stand inside of it, measuring two meters wide and over two and a half meters tall. The catch? Every single component had to be printed on-site during the Formnext exhibition. With only four days of the show and two days of setup, the clock was ticking. There was no room for error, just six days of continuous, high-stakes manufacturing.
Hijacking machines to beat the clock
We started by setting up fifteen Bambu Lab printers, running them non-stop. Early on, reality hit hard. Just building the frame's legs required ten full build plates per leg. With each part taking up to fourteen hours and eating an entire spool of filament, the math was not in our favor. To keep the project alive, we had to hunt down and hijack extra printers from around the venue, turning our small setup into a miniature, humming factory floor.
Printing a nine-kilogram tool head
The real test came down to the massive tool head. This single assembly required twenty-one individual build plates, over two hundred hours of cumulative print time, and more than nine kilograms of solid plastic filament. Watching the corner pieces and the oversized extruder housing take shape tested everyone's nerves. Any power failure or jammed nozzle would have ruined days of progress.
Victory at the final buzzer
Thanks to some incredible teamwork from friends and the onsite staff, the final parts finished printing just as the deadline loomed. We bolted the last structural elements together in the final hours of the very last day. It proved that with enough determination, a fleet of reliable machines, and a bit of DIY grit, you can bring even the most ridiculous scale models to life.
I 3D printed a gigantic 3D printer!
