Rare Alfa Romeo Tipo Restored With 3D Tech

A rare Alfa Romeo Tipo, one of just 12 Tipo 33/3 models made and previously featured in the Steve McQueen film, Le Mans, has had 3D technically used to help restore it ahead of it’s debut at the Goodwood Revival, the UK historic motor car festival.

The 1971 classic Alfa, owned by English racing driver Martin Stretton, approached KW Heritage with his Alfa Romeo Tipo 33/3, which had suffered front engine cover deterioration, causing ignition problems. A replacement part simply didn’t exist, so the company created one from scratch using “additive manufacturing” – also known as 3D printing. Taking on the task, engineers at KW Heritage created 3D scans of the engine cover that were imported into CAD. There the team re-engineered the part eliminating prior design defects while adhering to the FIA certification.

“Thanks to this technology and the skills of the guys at KWSP we’re now back on the grid with the knowledge that we also have spare parts should we need them in the future,” said Stretton.

Edward Smith of KW Heritage said: “By working closely with teams, restorers, collectors and vehicle owners, we are helping enthusiasts strike the perfect balance between old and new, with modern engineering techniques keeping the cars of yesteryear on the road for longer.”

The Tipo 33/3 raced successfully at Brands Hatch, Buenos Aires and Sebring in 1971 and is now owned by Martin Stretton Racing. It will be displayed on the KW Heritage stand at Goodwood Revival, where the firm will offer live demonstrations of 3D scanning technology.
