The finish looks like it might be laser with a secondary heat treating process (guessing). I think EBM is still producing a rougher surface finish than what we see in the photos.

When they improve EBM finishes comparable to laser they'll have a hard time keeping up with orders.

3D-printing for the design of future engines

This is a follow-up on an earlier post about Renault Trucks design engineers. Again, there's no mention of the technology used but the visuals are exemplary of the simplification and weight reductions that can be achieved with additive manufacturing.

Discover how Renault Trucks engineers use 3D printing for the design of engines of the future.
The idea is to reduce the number of parts and their weight thanks to the additive metal manufacturing process.
The gains on a DTI 5 Euro 6 engine are a weight reduction of 120 kg and a reduction of the number of parts by 200 units.
