Volkswagen is is making use of a new system identified as binder jetting to manufacture factors at its major plant in Wolfsburg, Germany.
Even though regular 3D printing employs a laser to create a component layer by layer from metallic powder, the binder jetting system employs an adhesive. The resulting metallic component is then heated and formed. Making use of the binder jetting component reduces expenditures and increases productivity, the factors weigh only 50 percent as a lot as all those built from sheet metal.
VW claims to be the only automaker making use of this 3D printing engineering in the generation system.
Christian Vollmer, VW manufacturer generation and logistics main reported: “Together with our associates, we goal to make 3D printing even much more successful in the decades in advance and acceptable for generation line use.”
VW has invested “an quantity in the mid-double-digit million euro range” over the earlier five decades in 3D printing. It has expanded an present collaboration with HP which is offering the high-tech printers essential and Siemens supplies the application for additive production. A key system phase worked on jointly by Siemens and VW is optimising the positioning of factors in the create chamber. Recognised as nesting, this strategy will make it probable to make 2 times as a lot of parts for each print session.
From summer season, the 3 corporations intend to build a joint crew at the 3D printing centre in Wolfsburg. The centre also trains workers in the use of these technologies.
By 2025, the goal is to make up to one hundred,000 factors by 3D printing each calendar year. The initial factors built making use of the binder jetting system have absent to Osnabrueck for certification: factors for the A pillar of the T-Roc convertible. These weigh practically fifty% less than regular factors built from sheet metal.
VW has already successfully executed crash exams on 3D-printed metallic auto factors. Until now, the generation of more substantial volumes was not price tag-helpful plenty of. On the other hand, the new engineering and the collaboration will now make generation-line use economically feasible.
