Ecco il papà della stampa 3D

Charles (Chuck) W Hull is the co-founder, executive vice-president and chief technology office of 3D Systems, whose business is based on the stereolithography process Hull invented in 1986. This was the first ‘solid imaging’ or 3D-printing process. Stuart Nathan spoke to him (and his wife) at the recent European Inventors’ Award ceremony in Berlin, where he won the Industrial Award.

The invention was aimed at speeding up the prototyping of plastic parts, he says. ‘Back in those days it was very difficult between when you had the idea and the blueprints to get the first part: It could take six weeks to two months; it was very slow,’ he says. ‘And when you got the prototype it was usually wrong; but you couldn’t start iterating and improving until you got it.’
