4D printing a printing method that works like 3D printing but includes as well a fourth component – the time component. Like this it is not only possible to produce three-dimensional objects but also objects that can change or move by getting in contact with sonsory triggers (e.g. water, heat).Why this is interesting for a Chief Digital Officer (CDO)?
3D printing is on its way to disrupt the classic hardware companies. Sooner or later, 3D printing will take a large share of the world market. Today it is often used in very special situations. In the aircraft industry, 3D printing is used very intensively. One of the reasons is that it is cheaper to print a special hardware part than to create and deliver it in an old-fashioned way. In addition, spare parts may only be needed in very small quantities. 3D printers are ideal for this because no large ordering processes, production processes (such as changeover times, etc.) and delivery processes are required.
