Mercedes starts 3D printing for metal parts
Mercedes-Benz Trucks has started using 3D printing to make certain metal components for older models of its trucks. A thermostat cover was the first 3D printed metal part to pass the company’s quality assurance process.
The company is using a process known as selective laser melting. Andreas Deuschle, head of marketing & operations in customer services and parts, said: “We ensure the same functionality, reliability, durability and cost-effectiveness with 3D metal parts as we do with conventionally produced parts.”
The working cavity of the laser printer at the centre of which a metallic thermostat cover has been produced for the first time using selective laser melting. When the work platform is raised, the powdered aluminium/silicon material moves to the side and the contours of the component become visible.
The view into the interior of the 3D printer shows the first printed thermostat covers, which are still connected to the work platform. After removal of the platform and support structure, the aluminium/silicon metallic powder is removed by suction, sieved, cleaned and ecologically fed back into the recycling system.
3D printing of plastic components is already established as an additional production method, and is particularly suitable for the production of smaller batches.
