Integrated manufacturing of automotive engine components using 3D printing to reduce weight by 21% and improve powertrain efficiency for mature modern products
The petrol and diesel engines of modern passenger cars are of all-aluminium design, with cost and weight optimisation using the latest conventional production techniques. The weight-to-power ratio of these engines has increased progressively in recent years, with mass-to-power ratios of around 1.1 kg/kw for 3- and 4-cylinder engines, reflecting the balance between material properties, load …
