The Open Source RepRap Simpson 3D Printer Design Reduces Friction, Uses Less Vitamins

Experimental-Delta-3D-Printer-300This is the Grounded Experimental Delta 3D printer aka the Simpson, a project built by computer science teacher Nicholas Seward that does away with the excess frames, pulleys, and hardware associated with earlier models. Seward wanted a machine that could print itself and used "less vitamins," namely metal parts that the machine couldn't create from scratch. There are still motors and controllers, but there are fewer in this model than in any other I've seen.
