I’ve blogged a few times over the past five months about 3D printing. It’s one of those technological developments which has attracted the attention of chemical engineers, despite some apparent anomalies.
Our profession spends much of its time producing items on a massive scale. We deal in huge volumes which provide food, energy, water and healthcare to hundreds of millions of people.
By contrast, 3D-printing operates in small numbers – even ones and twos. In fact, I think 3D-printing is synonymous with the phrase ‘hand-made’ – unique, custom-designed, high quality and carefully crafted. Who knows, 3D printing may herald the end of some traditional skills.
