I started to print the hull by starting with the section N°1 of the bow.

I had a very small problem with the deck coming off a few supports, the section is usable but a little deformed, rectifiable with very little filler.

But as I have another little thing that I don't like (a forgotten a wall in the front that deforms the deck), I reprint it.

The problem comes from the protective film of the glass that reduces a little the UV radiation, I put it in place a little while ago, it plays a little on the exposure times, especially on the layers of the deck.

I corrected it in the settings and now it's ok for the second copy of section 1.

I also printed the second section, it is very good. I keep the prototypes in general, it allows to show people how the printing of the ship is done.

In any case it will make a hell of a beast, it is far from being ridiculous next to the Bismarck at 1/200 too.

I am very happy with this first round.

You can see the flaw on the forecastle deck in low light. A useless transverse bulkhead that I forgot to erase on the inside. It causes a stretch on the deck indirectly during printing, a known phenomenon.

You can see some on the hull plating, because of the hawksbills which are very big and embedded on this ship, but there it's normal, there's nothing to do, it's unavoidable, except sanding a little.  :)

Section 2, I made an impression for the threaded rod nut that will hold the vessel and bracket, the nut will be glued on with Pattex bi-component glue.

Image

Image

Image

What's next:

Joining section 2, gluing and sanding.

Pause a transparent Rhodoid behind the portholes before gluing, it will not be accessible afterwards.

HOLY COW!

I've kept an eye on this thread from the start, and have really enjoyed seeing the 3D model coming to be. Now, seeing it printed and coming from a screen into your hands...wow.

Well done!

Pascal,

Very nice; I think I'm going to enjoy watching the assembly of the printed vessel almost more than I enjoyed the 3d development and I thought that was outstanding!

Indeed the printing is coming along nicely. There is quite a bit of leger de main involved in producing really good prints. At this Pascal really shows his experience.

Best regards: Tom

Printing such large pieces that need to fit together, such as the hull, is quite a challenge ... :thumbs_up_1:

Oh my word-- for a 1/700 fellow like me...

that is biiiG!--

well 1/200 scale is ... ! :cool_1:

a bit like comparing O gauge model railways to N gauge model railways :wave_1:

Tks all ! :thumbs_up_1:

Yes, it's a big baby.. :big_grin:

Printed and glued section 3 a few days ago, then sanded the joints until I couldn't feel anything with my fingertips at the glued sections.

Image

Image

Image


Printing of the last section N°4. It fits perfectly, it's not glued yet, I have some cleaning to do before and I have to put the Rhodoid of the portholes inside, because it won't be accessible once glued.

I've opened the deck at the level of the gun barbettes to be able to glue the rear 140 mm guns in casemate, not easy but it's ok.

Looks fantastic! I feel your paint on the hull plating: I just had to do a 1/96th scale model of Grand Central Terminal for work, and even though all of the brick lines on that thing are mostly straight-forward, it still took days of work to draw then boolean them out.

Really looking forward to seeing this finished. I love the French warships.

Thanks Devin! :thumbs_up_1:

Section 4 was very easy to assemble and glue, little sanding.

It's starting to take a turn in this case...

Image

The hull weighs 663 grams for the moment. A weight roughly equivalent to what would be its weight in injected plastic.

But much more rigid because of its design and material.

Printing the 2 pillars of the base in the same style as my Bismarck at 1/200. The advantage of 3D is that it fits perfectly the hull.

viewtopic.php?f=59&t=314096

The resin is easily scratched, but this is very superficial in fact, once painted it is not visible.

You can see the links of the sections that have been sanded. I still have to apply a primer to check if everything is perfect. At this level some of the sheet metal lines have been re-engraved with Trumpeter's "engraver" which is usually used for my model aircraft. I will also use it to clean the sheet metal lines loaded with sanding dust.

Image

Image

Image

I didn't do any embedding on this deck. I only made 2 holes for the 140mm barrels at the front to do a test.

With resin I'm a bit wary of precision. You always have to "play" a little. For deck 2, there are some recesses planned, I'll see what it gives visually, I'll decide if I should leave them or not. Deck 2 is easier to reprint than a hull or a section of hull.

As for the linoleum plates, you can see them perfectly without seeing them too much either, just fine, as I like, it's discreet.

Here there is just a micro-coat of spray primer to see what it does to the moiré surface of the deck. I want to know if I need to sand to 1000 again. I have a second coat to put on to see if it covers well, by finger, by not feeling anything..

By the barbettes, with a pliers, it is quite easy, there is a printing platform to put them and glue them.

That's why I opened the deck at this place.

I can even glue them very late in the assembly.

Tks! :thumbs_up_1:

Printing of a 340 mm prototype turret, there is not much to review, it is rather good. The assembly is well done respecting the tolerances of the resin 0.3 mm.

The printing is very fine thanks to the Photon Ultra, especially the padding and riveting.

I printed with 30 micron layers, but I'll test again at 20 microns.

I chipped the sealing skirt a bit when I was removing the paint, it's very thin there. No problem, it's a test. Otherwise it runs well with the system.

I've primed the hull, and sanding and repairing the little dings is in progress.

About the colors:

Extract from "Les Cuirassés de 23500 tonnes" Bretagne, Lorraine, Provence:

5. Paintings and particular marks :

51. Paintings :

The hull up to the waterline is painted green (Schweinfurth green), the deadworks and superstructures are bluish-gray, a classic color since its adoption in February 1908. Only the strake on top of the chimneys is black.

From 1915 onwards, i.e. during the test period, the steel of the 340 turrets and their guns was stripped and treated with a "grease plug" to prevent corrosion. These "grease plugs" contained a mixture of grease and lampblack, which gave the main artillery turrets the shiny black color that can be seen in photos from that period.

Towards the end of the war (1918), the upper half of the AR. mast was painted black to avoid the soiling caused by smoke.

In compliance with the Ministerial Circular of November 30, 1920, the waterline is painted black over a height of one meter (0.50 m on either side of the waterline 10).

The boats are painted bluish gray with white interior. The vertical parts of the deckhouses of the launches are kept "clear" or varnished if they are made of wood, otherwise they are painted in the color of the boat. The roofs are painted in grey for the steamers, in white for the launches.

52. Particular marks :

Since 1912, the particular marks of battleships and cruisers consist of white rings painted around one of the stacks. These rings allow, within a squadron, to identify the division to which a ship belongs and its rank in that division. The code used has already been explained during the presentation of the Courbet type battleships.

Between 1916, the year of their entry into service, and their first redesign, the three Britannies frequently changed their particular markings, so the study of the latter is the subject of a table in the appendix, common to all battleships of 23,500 tons."


If anyone has existing paint references for the bluish gray, Schweinfurth green, linoleum red ochre (Here can be the Tamiya XF-59 ("Linoleum Deck Brown")?

http://www.warpaints.net/viewtopic.php? ... 3&start=30

For the 380 and 140 gun turrets, I'm thinking of using two colors, a dark charcoal gray for the turret itself and a semi gloss black for the guns.

We can see on the 1915 photos that the color of the turrets varied according to whether a recent layer of grease plugs had been applied, from shiny black to medium dark gray. It must not have held up well in the sun, sea spray and rain.

Never heard of these ships before, but they sure are gorgeous.

Great work so far! :thumbs_up_1:

It is really taking shape now...!

excellent sanding and scribing!

its a most excellent transcription from 3-D digital into 3-D physical

questions ;-- I note that on many images of the black turret era ( my favourite!! )
( I am paying attention !! ) and in the photos

the ' black' is certainly lighter than one thinks

But there is a lighter stripe section- seems--painted -
I have never noticed this before .

was that a fleet identifier ? -or another purpose?
this is one of your images from BM
