OK here is our latest 3D print project, it is a crankcase for a new pylon race engine, it was printed by an online bureau.
The material seems pretty good, going to have tensile tests carried out on some test bars to confirm the properties.

cool, that looks very impressive, well done

Looks impressive that Barry. How does the cost of printing it compare to casting then machining? I assume that the bearing housings and cylinder bore for the liner will still have to be finish machined on a lathe or mill?

@john-minchell You have to consider the 3D printed part as a casting, meaning that it still needs machining for all parts such as bearings and cylinders to fit into.
The cost versus casting is dramatically less in favour of 3D printing in small numbers, casting would win out at maybe 30 parts, but this is a specialised engine, maximum will only 10 will be built.
