3D printing enables companies to manufacture products more efficiently and more sustainably. Products or components can be produced at any desired moment (on demand) so that the stock on hand can be minimal. Moreover, products can be manufactured close to the location of use (on-site), which reduces the number of transport kilometres and in turn reduces CO 2 emissions and fuel consumption. Additionally, every design is easy to modify to conform to the wishes of the individual customer. Or in other words: personalised products at reasonable prices.
