It's printed from ABS plastic, the same plastic legos are made out of. It melts at 220C. The strength of the piece is both contingent on its shape, material, and its in-fill pattern. I've never done controlled experiments with the pieces, So I can't really give you a specific measure. However, with certain parts with certain shapes, I've been able to stand on it, or make wall hooks from it. I used the Makerbot replicator.
