I've posted a few things before about 3D Printing. I'm now working on a project to 3D Print an entire model... this one is for static display, but much could be applicable to larger models that get wet.
The subject is the new Canadian Coast Guard midshore patrol vessel, a modified Damen 4207 design. The CCG is procuring nine of these; I'm modeling the lead boat, Private Robertson VC. Plans are not available... but there's enough info on the web about the base design that I was able to generate a reasonably close CAD model (along with the couple hundred photos I was able to take).
I have a more complete build log going on another forum, but here are a few pics to show what's going on.
And no you likely couldn't make an argument that the method is cost effective... unless you happen to have a commissioned job that provides an adequate budget! :-))

Most of the detail parts are Shapeway's "Frosted Ultra Detail", a high resolution multijet process. I used SLS (selective laser sintered) nylon for the houses... more fettling, but a savings. The hull is true Stereolith (laser hardened in a pool of resin), which I have access to but not through Shapeways!
-
Can't wait to get the RHIBs... a couple more weeks now...
Parts pending:
-
Some items just won't do as 3D prints... the stanchions are coming from Hauler in CZ.
The first try shown here... some problems with line thicknesses eating away at the parts... all adjusted now, waiting for the second try this week.
-
Love your work! how durable is the finished product for something like those gantry handrails?
-
Like any model railing: DON'T TOUCH!
-
Fair enough, what design software are you using? if you don't mind me asking.

Catia V5, but any good CAD package can yield the same models...
-
Clearly in a different class from your normal hobby 3d printers.
Very nice!
-
Beautiful work!!

The latest... all parts printed and in hand, starting to sand/prime/sand/prime/repeat, but to good effect- the 3D Printing evidence is getting well hid.
I used i.materialise (BE) for the RHIBs, but they printed my parts in Wisconsin for shipment to Michigan... 14 day turn around, not bad.
Pictures:
RHIBs;
Small RHIB, showing striations even with the SLA process;
Sanded and primed hull;
Hull & cabin, ditto:
A pile of PE stanchions... 123 on the real boat (yes I counted them!)
-
A little more progress. I'm having fun with the 3D Printed window glazing- perfect fit into all the odd holes!
-
Looks better with a mast on top. The yellow mast assembly is a single 3D printed part, though I might consider doing it in parts if I had it to do over again. All the little bits are printed too, except the ladder and railings.
-
My brother worked for the company that built them in Victoria before he retired. He said they are quite similiar to the RNLI boats here in the UK.
He use to come on here, but it depends where his RV is parked now.

Off topic a little , but how about a car

Victoria: Not sure what's there, but this lot of Canadian boats is built in Halifax.
Car: Best of luck to him, though I can think of any number of technical reasons why it's a BAD idea...
Back on topic: The window glazing is in place. We decided to tint the panes and not do an interior (whew). But each pane is polished both sides, and fits nicely in its hole, with a flange behind to hold it flush to the exterior. Gorgeous blue with the lid off, almost black with it on.
Lots of little bits to attend to still, but I had to get the CCG shield attached!

Hi Pat,
What most miss with the guy's car, is that he is only using the 3D printed parts to construct the buck/pattern from which he will take a mould then layup a body in that as per normal practice.
Back to boats, I've been using my 3D printer (build envelope 120mm3) to print hulls (in sections) of a 1903 tunnel hulled river boat which plied the Wanganui River.
The photo shows the first one at 1:48th scale with one of the crew, as a display model, while the larger 1:24th scale (720mm long) one will be r/c and electric powered.Keep up the great work
cheers

They were all built in Victoria, which is on Vancouver Island off the west coast of British Columbia, and then shipped out east, if you want to see a real one up close the is one in Port Dover in southern Ontario on Lake Erie. Probably a 3 hour drive from the Motor City.

Robert- Are we talking about the same boat? I'm quite sure the "Hero Class" mid shore patrol vessels are built at Irving Shipyard in Halifax, and as mentioned in this press release (and many other citings) from Canada's Fisheries and Oceans site:
http://www.dfo-mpo.gc.ca/media/npress-communique/2009/hq-ac36-eng.htm (http://www.dfo-mpo.gc.ca/media/npress-communique/2009/hq-ac36-eng.htm)
And on CCG's site:

And on Irving's site:

Thanks, I did get to see a real one up close. I have hundreds of photos taken aboard Private Robertson V.C. when she was moored at the CG dock at Amherstburg, across from Detroit in May 2013.

Not all is printed! Spending a couple cheerful days assembling the brass railings. These could be done in 3DP, but they would be very fragile AND bulky looking. Sometimes brass is best.
Soggy bits of tissue work well as heat sinks to protect the plastic deck and paint. The water boils when I solder the lower rail!
The stanchions have 2-1/2 holes... the top rail sits on top of the stanchion, a real joy to hold in position while soldering.

beautiful work

Hi Pat,
Not quite wrong, just a few feet shorter,
www.seaspan.com/shipyards/shipbuilding_history.php
and click on the Victoria pdf file.
The one's my brother worked on were slightly shorter version of the ones started in 2011, besides he has been retired for a few years now.
Hope the link works as for some reason I couldnt copy and paste it.
-
Ah, 47 feet, 47 meters... hardly worth talking about the difference!

Coming along... I can smell the finish line!
-
Hi Pat,
looking very neat.
Your modelling skills on the non-printed items, and excellent painting, make for a very professional job, worthy of a glass case in any corporate office or museum
well done
vnkiwi :-))
-
great stuff! love the crispness of it all.
-
Yep, has has been echoed before, great skill and a lovely looking model.
Si:)
-
Thanks all. Finished a little while ago, here are the final glamour shots.
3D Printing can be fun!
-
The 5th ship of the class - CCGS G. Peddle - was accepted by the CCG on Friday. The 8th ship - CCGS M Charles - was reportedly almost ready for painting on Sept. 11. It's a 9-ship class, and as soon as #9 is launched, the 'Module Shop' assembly building will be torn down; part of an upgrade for the yard.

Does that yellow circle with the X in it indicate the eventual location of a .50-calibre machine gun? :o
Until then, I suppose that those big POLICE signs on these ships will terrify the 'bad guys' into surrendering. :police:

The yellow X is, I believe, a helo drop target. The black rings just forward are for mounting the proposed machine guns. The CCG is a civilian organization, and there are issues (political?) with arming their units. That's why they embed police units for interdiction work. The police have their own berths and operate the boats.
Picture: Mounties training on the boat.
-
Ah, yes, the weapon mounts show up very well in that last photo! Thanks!
'Political' issues? I could discuss that topic for weeks-on-end >>:-( , but MBM isn't the right place. :police:

3D printing a bit off topic
In this months PBO (Practical Boat Owner November) there is an article about 3Dprinting ,this guy made his own .At the end of the article the are links to sites that he used.He has made parts for his real yacht. Thought this to be of interest to the electroniclly minded ,

Now that I've thought about it, I realize that the CCG/RCMP manning makes good sense. The RCN would have a crew about 3x the size of the CCG crew, so that's a cost saving.

That looks brilliant very nice.
-
This is AWESOME - I wish I could print out models like this. :-))
