I'm building a giant 3D printer from scratch, the printer will have a print volume of 1000x1000x1420 mm. Everything you see in the video has been designed and 3D printed by me and the files will be available on my website www.ivanmiranda.com when the project is finished.
I'll be using a Slice Engineering magnum plus hotend and It is controlled by a Duet3 MBHC which is a fantastic controller, check it out!:

The bed frame is lifted by four Nema23 motors with a 47:1 gear ratio and it already weighs 15 kilos without the bed heater or surface so this is going to end up being a heavy one, but you'll see in the video that that won't be an issue. The motors are being run at 1.2A for the stunt at the end of the video so I have plenty of power to lift whatever I decide to print.
