SSAB prints a labyrinth seal from a 1950s drawing, final checks pending
SSAB and RISE have built a replacement oil seal for a rolling mill in Borlänge using directed energy deposition, starting only from a technical drawing dating from the 1950s. The part, about 420 mm in diameter, was made in SSAB's own AM TS2 powder as part of the On Demand 2033 programme. CT analysis is still outstanding before the part is installed, so the spare-part route is not yet proven in service.
