This is a significant accomplishment not just for Siemens but for the 3D printing industry as a whole because implementing this part required undergoing stringent certification and qualification processes spanning several months.
The news further validates 3D printing as an advanced manufacturing technique.
The 3D printed part
The part in question is a metallic impeller for a fire protection pump.
The impeller is 108mm in diameter and in constant operation.
Krško nuclear power plant has been operational since 1981 with this part, however the impeller is no longer manufactured.
The part was recreated in Finspång of Sweeden, Where Siemens Additive Manufacturing unit takes place.
Using Selective Laser Melting or SLA, the ultimate goal was in hand to reach.
After making, the final product was sent back to validate and be certified for implementation.
Fortunately, Siemens is happy now since their job was too good to be used.
