US 16 inch Howitzer Model E RR gun
US 16 inch Howitzer Model E RR gun
Hi - I know this is the "Axis" history forum but thought I would share one of my other projects.
I got tired for a bit doing mostly Axis stuff and needed a short break
This is the first 1/72nd scale model I have done using 3D printers and thought
I would show anyone interested some preliminary results. I was surprised
the tiny little sight even printed (see next to finger). I did a base ring and the
roller mounts just in case I want to display it with out the railway trucks. I will
need to redo the railings as they did print but there are just too small for me to
install without breaking.
I like the weird stuff I guess and this is a US 16" Howitzer Model E circa 1915.
Only a prototype was built before they realized they didn't want to go to the
trouble of building a firing pit to get any sort of evaluation out of it. The same gun
was then installed on a new carriage.
Regards & Happy Modeling

Hi - as a test, I decided to try and print one of the 2 axle truck assemblies on my Form 2 3D printer just to see if the printer could do it - I was surprised by how well it did. The part shown still needs to be cleaned up a bit more but details show up quite nicely. The springs printed as well but I accidentally chopped a couple of them up when cleaning it (next time I will be more careful). Scale is 1/72nd. The cost of the truck assembly through Shapeways service is about $11 (+ $5 to ship). The cost on the Form 2 was about $2.
just sharing a few test prints -

Hi - one of the benefits of desktop printing and digital modeling is that you can
scale to anything you wish and just hit the print button again....
1/35th scale version next to the 1/72nd scale version printed previously
My ultimate goal is to print every known railway gun in 1/35th scale... we will see if I get there

Re: US 16 inch Howitzer Model E RR gun
Hi - just a quick couple of pictures showing a sprue I made for some of the smaller parts for the model (1/35th scale version).
The print failed in one corner and several parts had uneven edges but it actually did better than I thought it would.
The hand wheel pic shows that detail is a bit soft but this would have been extremely difficult to make (at least for me).
Resin is still the cheaper 3rd party type, print time was about 3.5 hours and material cost was about $.8 (80 cents).
I will reprint using the higher quality Formlabs resin later in the week so as to make a comparison with the cheaper resin.
Regards

Re: US 16 inch Howitzer Model E RR gun
Still a work in progress.... I had to increase diameter for the
railings I originally had and reprint them. I included a picture of
the railing set "as printed". I also added a couple of other small parts,
started to clean up rough surfaces and gave it a coat of primer.
Still need to add some hand wheels for manual brakes and some chains.

Re: US 16 inch Howitzer Model E RR gun
I envy your abilities! I think this is a good thing to show on the forum, historical models are probably one of the reasons we all ended up on here. Perhaps at some point I'll get around to detailing my 1/2400 warships and post a few pics of them. Are you using Shapeways for printing, or do you have your own printer?
Re: US 16 inch Howitzer Model E RR gun
Hi - thanks much.... totally agree. I very much enjoy the intersection of mechanical technologies, history and modeling.
I bought a Form 2 3D printer about 6 months ago and I now only use shapeways for a few detailed parts that
are better suited for "supportless" printing. Absolute detail is a bit better using the high-end Shapeways printers but they
are just too expensive for larger parts. Most prints for larger models like the RR guns I am doing are about 1/10th the cost
using the Form 2 printer (enough to pay for the printer fairly quickly)
Kind Regards and happy modeling.
