New Cost Saving 3D Printing Metal Application Helps Innomia Increase Production

Magna, an automotive component engineering and supply company, was having difficulty optimizing the mold used in the injection molding process for a component for the central front armrest of a Å*koda car. The heat of the mold needs to dissipate uniformly in order to minimize distortion and to maintain the high quality of the part required. Unfortunately the tool that was used to shape the injection molded part was made with a beryllium-copper alloy which has a high thermal conductivity, but only from one side which made the temperature distribution highly uneven. The company decided to 3D print a new insert using their EOS direct metal laser sintering (DMLS) 3D printer with an integrated system of conformal cooling channels that were only 3 mm wide. The part was 3D printed on an EOSINT M 270 using a maraging steel powder material, a low-carbon metal that is known for exceptional strength.
