A terminally damaged 103-year-old Delage Type-S race car suffering a blown engine was brought back to life by way of laser-scanning and 3D-printing technology, reports ABC.
The centurion race car was regularly driven and enjoyed by its owner Stuart Murdoch in Australia before grinding to a halt in 2014 after its engine block suffered a crack.
Being the last of its kind in the world, and older than any living mechanic, there were no spare parts available for repairs, or even original drawings to reference. Thus, pre-war motorcar engineer Grant Cowie was forced to find an alternative way to rebuild the Delage’s once-state-of-the-art 16-valve inline-six engine.
“I knew that to use the traditional method, which involves a wooden pattern, would be prohibitively expensive and with such a complicated casting it was possible it would take several attempts to get it correct,” said Cowie.
He turned to laser-scanning and 3D-printing technology to create a very accurate sand-mould cast of the engine’s block, which was later used to cast the iron block at a local foundry.
The block was then machined using traditional methods before the engine was reassembled and fired up.
“I had faith in them and I wasn’t disappointed,” said Murdoch of the restoration staff after witnessing his Type-S fire up for the first time after its restoration.
