What is it?
4D printing is the expansion of 3D printing by adding time as fourth dimension. As in 3D printing a solid 3D object is produced by a printer, but the composition of the building material is such that the printed object can change its shape in the course of time. 4D printing allows the manufacture of objects that consist of a single complete structure that is able to change its shape under specific conditions. Think of inbuilt pivoting points, pressure points or electronic components which allow a product under the influence of light or changes in temperature to increase in size only in a specific part, and not as a whole. At this moment 4D printing is still at an experimental stage. Already scientists are working on appliances able to assemble themselves, but these are mostly minuscule appliances at the nanoscale (e.g. biochemical sensors), electrical parts or appliances able to transport medicine to the right location in the body. If this technology develops further it may lead to new types of sensors that can be integrated in medical equipment to detect all kind of measurement values.
