A giant 3D printer aims to produce a life-size boat

As 3D printers become more ubiquitous, the number of custom designs and styles of printers has exploded. From different print materials and technologies to printhead movements, we've seen all sorts of different versions of these tools. But one thing that has been largely limited to commercial and industrial use has been large print sizes - consumer-level prints have to be split into multiple pieces to fit together later. Not so with this giant 3D printer from [Ivan].

The design goals of this release are to print an entire boat that [Ivan] can drive himself, as well as a complete kart chassis in one piece. It's part of a contest between him and another YouTuber and as far as we can tell, he's well on his way to meeting the challenge. The printer will be able to process 4kg of filament per day and has a printable volume of 1000 x 1000 x 1420 millimeters, or just under 1.5 cubic meters.

Although this video is only the first step in building the printer frame and guides, we can't wait to see the next steps in the process. It's one of the greatest 3D printers we've ever seen, at least outside of printers designed to build entire houses out of concrete.
