Alright, 3D Printers exist. They’re machines you can simply buy for a few hundred dollars, set them on your desk, and have them start churning out plastic parts. A little pedestrian, isn’t it? How about something you can take into the field for a client, and print out some new parts right there? How about sending a printer to the latest humanitarian crisis? After all, all those humanitarian uses for 3D printers we’ve been hearing about won’t do any good without a 3D printer.
TOME is [Philip]‘s attempt at portabilizing a 3D printer and also his entry into The Hackaday Prize. The preliminary goals for TOME are the ability to print for four hours on a single battery, an auto leveling bed, and an accessible hot end that’s easy to replace.
Already the design for TOME is rather interesting. The astute printer aficionado will notice there is no stepper motor on the X carriage. The task of moving the head in the X axis is taken care of by a stepper in the base, with a square shaft and set of gears moving everything back and forth.
With this odd yet ingenious motor setup, the entire printer is able to collapse in on itself, allowing it to be installed in a waterproof plastic case. That’s something you’re going to need if you’re taking a printer on the road.
The project featured in this post is an entry in The Hackaday Prize. Build something awesome and win a trip to space or hundreds of other prizes.
