Additive manufacturing is far superior to usual printing, as well as to usual designing and manufacturing. Being able to create a 3D object in a matter of hours is not only entertaining, but also very productive. Imagine engineers trying out new prototypes without spending time and money on hard casting or machining new parts and then assembling them into a device that doesn’t even work. Now all these steps can be omitted, printing a design, trying it out, changing it and printing a new one takes a few hours and is far more efficient. Not to mention that the possible applications of such devices are endless, from engineering and health care to food production and mass manufacturing of fully functional electrical objects, like mobile phones.
