The lofty goal of making sure every school kid has access to a laptop has yet to be reached when along comes an effort to put a 3D printer in the hands of every kid. And not just any printer – a printer the kid builds from a cheap kit of parts and a little e-waste.
The design of the Curiosity printer is pretty simple, and bears a strong resemblance to an earlier e-waste 3D printer we covered back in December. This one has a laser-cut MDF frame rather than acrylic, but the guts are very similar – up-cycled DVD drives for the X- and Z-axes, and a floppy drive for the Y-axis. A NEMA 17 frame stepper motor provides the oomph needed to drive the filament into an off-the-shelf hot end, and an Arduino runs the show. The instructions for assembly are very clear and easy to follow, although we suspect that variability in the sizes of DVD and floppy drives could require a little improvisation at assembly time. But since the assembly of the printer is intended to be as educational as its use, throwing a little variability into the mix is probably a good idea.
The complete kit, less only the e-waste drives and power supply, is currently selling for $149USD. That’s not exactly free, but it’s probably within range of being funded by a few bake sales. Even with the tiny print volume, this effort could get some kids into 3D printers early in their school career.
