Thanks so much, Rory! Very happy to hear you are happy with the parts!

Hi Russell! For the gray resin parts, I recently purchased a high-quality resin 3D printer and now do my own printing. Products printed in gray resin link:
https://www.model-monkey.com/

I can print for others, no minimum.

My Shapeways shop remains open, too, for those that prefer designs printed in materials other than gray resin. Nameplates 3D-printed in real metal are available in that shop, too. Model Monkey on Shapeways link:
https://www.shapeways.com/shops/Model_Monkey

Rory, very happy for you!



Wow! Stephen, now that's commitment!

Thanks so much, Rory!

New designs coming! I think you'll be even happier.

Really enjoying your build!

New Main Battery and Fire Control directors ordered!

Now if I could make a request about possible future items for the store? What about blast bags for the various caliber guns. I have looked online and I can only seem to find them with other stuff i.e. The lion Roar set which has resin bags and turned guns along with PE @ $150+. I do however see tons of suppliers of just the gun barrels.

I have several kits that need blast bags and I would be all something like that

Oh yes, Rory! You can't beat resin parts!

Stephen, who do you use for your printed resin parts? I've found a site here in Australia, but they have a minimum spend making it painful to say the least.

I received the parts today and all I can say is Holy Cow, what a difference. The resin is smooth and perfectly formed. No striations at all. All the detail is very well defined and clearly visible. In fact my only concern is I think the detail may be too 'To Scale' as I worry the paint will cover up some of that gorgeous detail.

It sounds and looks like a massive improvement in quality. I am looking forward to seeing the difference and I can say that just by looking at the pictures on your website that I will most likely be ordering new Main Battery and Fire Control directors to replace the ones from Shapeways.

3D Printing is the way of the future fellow modelers!

Thanks, Russell!

Yes, 3D-printed gray resin is a very good material for scale modeling. IMO, it is better than some other 3D-printed materials, including nylon and white acrylic. I think the new mounts will be an attractive alternative for Rory's model.

Here's why in detail:

Shapeways offers several different materials, nylon being one of them. Shapeways calls their 3D-printed nylon "Versatile Natural Plastic". The products that Rory ordered are printed in a different material. His are printed in acrylic plastic which Shapeways calls "Fine Detail Plastic", formerly called "Frosted Detail Plastic".

Shapeways does not offer gray resin, not yet anyway.

Each of these materials has advantages and disadvantages. Nylon, as you experienced, is difficult to finish because fewer kinds of paint will adhere to it. But many large scale modelers like nylon for RC purposes because of its strength. Google "primer for nylon" and "paint for nylon" to find paints that will work with it.

White acrylic, the material in which Rory's current 3D parts are printed, is smoother than nylon, captures fine detail better, and accepts acrylic hobby paints. But white acrylic requires a lot of preparation. Not only does the surface roughness often require further smoothing, the model has to be "post-cured". "Post curing" involves exposing the model to sunlight or another UV light source for an hour or so to make sure all the acrylic has fully cured before painting. If any uncured resin is present, the uncured resin can prevent enamel paint from hardening on it.

When the white acrylic model is being printed, a waxy material is also extruded by the 3D printer simultaneously with the acrylic to support overhanging features. Although Shapeways melts away the wax in a low-temperature oven before the model is shipped, some wax may remain. Any waxy residue has to be cleaned away by the modeler, not easy or pleasant. When the hot wax comes into contact with the acrylic during printing, the surface there will be rougher because the wax deforms slightly as it begins to support the overhanging feature.

And 3D-printed acrylic, which is chemically related to Plexiglas, is expensive.

The new gray resin material is so much better because:
- surfaces are dramatically smoother than the other materials.
- uses no wax or other mold-release agent.
- accepts enamels (Colourcoats, etc.), acrylic and metal (Alclad2) hobby paints and Molotow paint marker paint without the need for primer.
- gray resin is less expensive than white acrylic.

Instead of wax, the gray resin printer creates physical supports that look like sprues to uphold overhanging features during printing. Models like turrets and fire control directors are good subjects for this new material. Their boxy geometry means that the supporting sprues can go on the bottom of the model where their contact points are normally hidden. For larger models, they can be found on the inside where their contact points are generally hidden, too. A common cuticle clipper is a handy tool to easily remove them.

I'm excited to see what Rory thinks of the new gray resin material compared to the white acrylic mounts he has. Both the mounts he has and the mounts coming are printed from the same 3D design. So the big difference is only the material.

You can read what some other modelers think about the gray resin parts they have received here:

Hi Rory,

I'm the designer of the 3D-printed acrylic parts you ordered from Shapeways. Thanks!

I am happy to announce that most of my designs are now available in a new 3D-printed material, gray resin, which offers dramatically smoother surfaces, no waxy material cleanup, accepts acrylic and enamel hobby paints without the need for primer, and is less expensive.

I'd like to send you a set of 5" mounts in the new gray resin material, my treat. Please let me know your mailing address and if you'd like the set with fixed or separate trunnions. Both types can be found here:
https://www.model-monkey.com/battleships-350

You can see how the set with separate trunnions looks here:
https://www.model-monkey.com/product-page/1-350-5-38-mk-28-mounts-for-fast-battleships-separate-trunnions

Shapeways is not yet offering this material but products printed in gray resin can be ordered directly from me:
https://www.model-monkey.com/

Really enjoying your build!



Steve, it's great to see parts beginning to be offered in resin as opposed to shapeway's nylon, which is very difficult to paint IMHO! Great decision!

Looking forward to seeing what you can do with them Rory!

Replacement PE has arrived so I am finally a happy camper again. I have also done some progress on the main guns. I received a dremel tool for my birthday and that's made drilling out the mounts to receive the turned brass barrels much easier. 5 down, 4 to go!

However I think this build will be on the Dry Docked 2019 Campaign because 2 of my tankie thingie campaigns just started and I am also in a wingie thing campaign too

Beginning to think I may be cursed. My replacement fret arrived in the mail over the weekend. I happily opened it and discovered....A set of PE for a 1/32 Mustang P-51D.

When the get it wrong they get it really wrong.

I have gotten hold of their customer service again and they are allegedly sending out the right fret *again*

Only good part is they don't seem to want the Mustang fret back so that's something I can sell or trade at a later date.



I ordered the Tamiya IJN Musashi 1/350 from a hobby shop in Japan and they sent me two of them and only charged me for the one. They didn't want the other back which was nice, but to this day I cannot convince the wife I only paid for one and not two.

That's a real bummer about the missing fret, Rory!

Hopefully you'll be back on track soon!

How'd you go painting the shapeways parts?

I have real issues with them in terms of painting: Grainy surfaces that require sanding; and because the parts are nylon, paint wont stick!

Update: Eduard are sending me out a replacement fret (which I had to pay for) The shipping was almost the cost of the replacement which is irksome. Allegedly the fret is in stock and is being packaged as we speak.

Missouri is on hold till it arrives so hopefully it doesn't take too long.

Aaaaand we have run into a snag which has taken the wind out of my sails. I was going along quite merrily when I discovered to my horror that my Eduard PE set is missing an entire fret. Up to now I had been using the PE set sourced from China so had not opened the Eduard set.

I have emailed Eduard to see if I can get a replacement.

Its not entirely bad news because almost everything on the fret is also present in the Chinese set. HOWEVER I think the Eduard set had some more detail on those pieces.

Long story short I lost all enthusiasm to work on the kit tonight. I will wait to hear back from Eduard before recommencing.

On the actually progress side I have the deck on the hull now and the majority of the lower superstructure complete. Putting all the hatches on was a pain in the behind. Threw on a light coat of primer to look for issues. There are less than expected which is nice



I also threw on some primer on one of the 3D Printed 5" turrets. There are definitely striations visible even with a primer designed to fill small scratches.


Side that's been sanded.


Side that has not.

Shouldn't be too much of an issue to sand them out.

Rory,

Your Missouri is definitely starting to look the part! Replacing entire bulkheads with detailed photoetch sheet is an interesting approach... I've always added all those bits one at a time, but this looks like a big time saver for a similar effect. I'm interested to see how all this will look under paint. Great work so far!

Rory,

Good thing the Missouri was built in the 40's. If you add anymore metal you would be in violation of the Washington Naval Treaty....LOL.

Sounds like you may have to do a lot masking to work around your problem with sub-assembly and the deck.

Enjoying you build.

Mark



There's a lot more metal to come!

Looking at the instructions I believe I have reached the point where sub-assemblies are now possible which is good news. I am going to leave the superstructure for now and get started on the deck. Lots to do before I can glue the deck to the hull and throw on some paint.

I am undecided if I am going to leave my wooden deck the wood colour or spray it deck blue.

Has anyone sprayed a wooden deck and how did it come out?

This weekend we had Progress!

I replaced the prop shafts with copper rod which worked really well. With that the hull is complete and ready for paint which will be done once I have the deck installed.

Speaking of the deck I ran into a slight hiccup with my plan to build up the superstructure in segments. The way the PE works it spans multiple subassemblies so I am going to have to deal with that when it comes time for painting and wooden deck install.

That being said I got a lot done on the superstructure. I went from dull featureless slabs of plastic like this:



And ended up with:





Still lots to do just with what I have done so far. Have to clean up joins, add watertight doors etc. Plus keep building up the superstructure.

Fingers crossed this PE has been some of the easiest I have ever used. Fits perfectly and looks good.
