Making a Treadmill into a 3D Printer
We’ve seen a 3D printer that can output long items on a conveyor belt. Makers Ivan Miranda and Jón Schone took that idea and upscaled it, replacing the small belt unit with a full-size treadmill. After building the 3D printer’s X/Y mechanism, he used it to output an I-beam as big as the ones used in construction. We can’t wait to see them print a kayak with it.
