3D Printed Yachts?

I was thinking about all this fuss about 3D printing. Is it a matter of time until we see a 3D Printed AWB? Even if not in the final product I can see how this will change the way moulds are made.

Closer than you think - I believe some makers already use giant computer-controlled milling machines to cut out foam plugs exactly to the designed hull shape.

That is certainly the case with dinghies.
Even some amateurs are CNC routing moulds, plugs, parts.

We've recently got a 3d printer where I'm working. In general it seems to be slower than when I was able to scribble a rough sketch and ask Rachel to get her dad to make it.
A few people have talked about sharing the effort of sorting out a REP-RAP but a couple of us decided it just created the need for a DIY foundry using the printed bits as lost wax patterns.

I passed a great hull up the Wear

it was one of a pair of steam tugs built in the 30's

one got hit by a bomb and smashed into a hundred bits

they lost confidence in the other so they stripped it and dumped it up the river in 1944

the hull is a wonderful shape and still looks ready to float again

amazing

The history of that hulk is rather unclear; There are certainly records to show she was one of three ferro-cement steam tugs built after the First World War (1919) by The Wear Concrete Building Co. Ltd. They were the CRETEHAWSER (the one surviving as a hulk on the R Wear), the CRETEROPE and the CRETECABLE.

None of them had long lives; The CRETECABLE was sunk off Yarmouth before being finally wrecked in 1920 off Wheathall Point, Whitburn, Sunderland after collision with trawler LORD CECIL. The CRETEHAWSER was converted to a hulk in 1923 before being broken up in 1924.

The CRETEHAWSER was stripped and used as wave break in 1936 before being moved up river.

None of them appear to have lived long enough to be hit by a bomb.

curious

the info I got was from the river patrol

he said there were just two of them

thanks for this

any more links you can send me

she had a lovely stern and looked in pretty good condition given her age

How about having a 3D printer onboard to make replacements for tools and parts that break or were left behind? NASA is planning to do this on the Space Station < http://www.cnn.com/2013/08/13/tech/innovation/nasa-3d-printer >. Studies are underway regarding using 3D printers to fabricate food items (Yummy!) < http://www.nasa.gov/directorates/spacetech/home/feature_3d_food_prt.htm >. 3D printing is already being used to manufacture rocket components that are difficult to build using conventional machining processes < http://www.nasa.gov/exploration/systems/sls/3dprinting.html#.UhA4tNLVA98 >.

Regarding concrete ships, there is a breakwater formed by nine concrete ships at Kiptopeke Beach near the mouth of the Chesapeake Bay. The ships were built during WWII and were sunk to form the breakwater in 1948 to protect a ferry terminal. The ferry operation closed in the early 1960s following the construction of the Chesapeake Bay Bridge Tunnel. The ferry terminal subsequently became a state park < http://www.dcr.virginia.gov/state_parks/kip.shtml >. The concrete ships now protect a boat ramp, fishing pier, and anchorage for small craft. The concrete ships now have large cracks and holes in their sides, but they probably have survived in better shape than steel ships would have.

It would be excellent to be able to print out parts for the boat in remote ports in the med or elsewhere worldwide
