A team of Renault Trucks engineers and designers is working on an additive manufacturing process – metal 3D printing – that is set to boost the performance of engines. Technology of the future is fast becoming a reality, as can be seen from the complex parts that have already been successfully tested inside a Euro 6 engine.
The Renault Trucks Lyon Powertrain Engineering department has focused on using metal additive manufacturing as a future engine manufacturing process. A prototype DTI 5 4- cylinder Euro 6 step C engine has been designed exclusively using 3D printing.
Although the complete engine was already designed virtually, rocker arms and camshaft bearing caps were manufactured by metal 3D printing and successfully bench-tested for 600 hours inside a Euro 6 engine. "The aim of this project is to demonstrate the positive impact of metal additive manufacturing on the size and weight of an engine. This process has enabled us to reduce the weight of a 4-cylinder engine by 120 kg or 25%", explained Damien Lemasson, project manager at Renault Trucks. "The tests we have carried out prove the durability of engine components made using 3D printing. It's not just cosmetic."
"the next major user of metals AM technologies"...
I would just like to see Aerospace become a "Major User" of AM technologies...
HW was suppose to have put in a big order last year but that apparently didn't happen... heck even GE Aviation apparently didn't put in a big order... where is RR, Airbus, P&W ?
Lots or rosy articles about the greatness of AM but few POs...
Perhaps the policies changed at Arcam after the GE investment and we will see great things at the Q.. time will tell...
