Earlier this year, the Free Software Foundation announced a hardware endorsement campaign
for hardware that respects the rights of its owner (no DRM, runs Free Software, support for open formats, no or freely licensed patents, etc.). Now, they've announced that the Lulzbot AO-100 3D Printer
is the first device to pass certification
and be endorsed by the FSF. Source code to both the hardware and software
is available, naturally.
