Headline: "3D printed ... robot arm..."
That's amazing!! So many makers are only able to 3D print a few crummy plastic bits. But here we have a story about an actual "3D printed robot arm", including it implies the electric motors with windings, bearings and permanent magnets (the magnet paste has tended to jam up most prototype magnet printers), insulated wiring, encoders, nuts and bolts already torqued at printing.
Congratulations on this fantastic accomplishment. Printing out a complete robot arm, wow, fantastic, amazing.

Oh, I see. A few crummy plastic bits. Not a "robot arm".
But soon. Soon we'll be able print out things at home. Mobile phones, food, flying cars...
