Could you print a 3D Ceto buoyant actuator?

"Cornwall-based wave energy developer Seatricity will spend the week of 13 to 18 July tank-testing a 3D printed model of its Oceanus 2 device in Ireland."

There are several points of interest in this article:

- Seatricity will be part of WaveHub, as will Ceto 6.

- Oceanus 2 will be tested at the Beaufort facility at the University of Cork, (CWE has links to the same facility).

- The scaled device has been 3D printed.

The last point is the one that interests me most because a couple of years ago I posed the question, could a buoyant actuator be constructed using 3D technology?

It appears that it could going by what Seatricity have managed to do with this model.  If you can print a small one, you should be able to print a big one, no?

From what I have read, if you can draw it, you can print it.  It opens up the possibility of using materials that are non corrosive in saltwater, (if not for the BA, then maybe for other components).

I know that they have been able to print the hull of a sailing vessel and that they are working on printing a full scale house.

It may be many years before this would seriously be considered, but who knows?

One thing we do know, is that some of the collaborations CWE has entered into, includes the voluntary sharing of some intellectual property.  This may fall into that category.
