3M Buckley Innovation Centre reverse engineers legacy Leesona winder part with 3D printing

March 06, 2019 / Sam Davies

3M Buckley Innovation Centre has applied 3D printing technology to provide a replacement part for a Leesona winder, which is used by Wyedean, a military uniform manufacturer and supplier to the Armed Forces.
The Yorkshire-based company has been serving the military for over a century and turned to 3M BIC when a component of its legacy Leesona winder broke. This machine was made out of cast iron and manufactured 70 years ago, meaning spare parts weren’t so easy to come by. 3M BIC’s design team was sent the broken part which was missing three of its fingers, which held the cardboard inner roll of a thread spool in place when the machinery was in operation. Without it, production would be halted.
