2018-12-17

The Volkswagen brand’s Toolmaking unit is adding a 3-D printing center to its facilities in Wolfsburg. With the opening of the center, the unit is bringing the most highly advanced generation of 3-D printers to the Volkswagen Group, which will allow the production of complex vehicle parts in the future.

In addition, with the new center, Toolmaking is implementing a key point of the pact for the future concluded in 2016 and expanding its production competences with subsidies from the Innovation Fund II.

The new generation of 3-D printers developed in cooperation with HP is the most modern within the Volkswagen Group and is based on the binder jetting process, which supplements the previous selective laser melting (SLM) process.

To date, the Volkswagen Group has mainly used the SLM process for 3-D printing with metals. In this process, the material used, such as steel, is applied to a base plate in a thin layer. A laser beam then melts the powder at the points where the component is to be created. The molten powder hardens, forming a solid material layer. The new printers at the center will now allow the use of other 3-D printing processes such as binder jetting.

In this additive process, components are manufactured using a metal powder and a binder applied in layers. The metal part which has been printed is then “baked” in a sintering process. In future, the various processes, which each have specific applications, will supplement each other in an ideal way.
