ExOne reveals BMW’s use of binder jet 3D printers for Collection 3 & Collection 4 engine cores

ExOne and BMW have revealed how the latter is utilizing the previous’s binder jet 3D printing know-how.

Having labored collectively since 2002, BMW operates 4 of ExOne’s Exerial sand 3D printers, with two further ExOne machines slated for set up sooner or later.

BMW runs the machines at its Landshut Gentle Metallic Foundry, which is the automotive firm’s largest plant for casted elements with greater than 3 million components, akin to cylinder heads, manufactured yearly. This facility is taken into account a lightweighting centre of excellence because of the concentrate on intelligently designing elements for efficiency and gasoline effectivity.
