Our May series focuses on the cool technology behind open hardware, and LulzBot maker Aleph Objects wants to help us celebrate by giving away 3D printers to two very lucky readers.

This giveaway marks the first time we'll give away a LulzBot Taz 6. The top-of-the-line model retails for US $2,500 and boasts a print area of 280x280x250mm (nearly the size of a basketball) and a heated print surface.

The runner-up will receive a LulzBot Mini. With a print area of 152x152x158mm and a US $1,250 retail value, it's great for hobbyists looking to try 3D printing for the first time.
