I built some some custom 4-pounder guns, Swivel guns, and anchors using the open-source 3D modelling program "Blender". We just got in our first "prints" which came out better than expected in detail. They're a wee bit grainier than if they'd been cast (or certainly lathed). But after a little light sanding and painting, they'll be fine. And at 1/72 scale, hardly noticeable to my eyes. The 4-pounders are under 1" long. and the swivels are far smaller. The beautiful thing is now that the models are built, I can easily adjust them to print out at any scale needed. If anyone needs any, they're available at http://www.shapeways.com/shops/modelshipfittings I definitely recommend their Frosted Ultra Detail material. It looks like frosted glass, and offers the smoothest finish and detail. Now that we have the guns in hand, I can see that we need to adjust the height of the gunwales before we get into planking the upper wales and gun ports. They had seemed a bit short. But I have to raise the height by about 1/8" (9" scale). That's what I get for drawing my own plans! ![]() Anyway, it'll be good to be under way again! ![]() ![]() ![]() ![]() ![]() ![]() | ||

I have no idea how to even start. do you think something like tis could be modeled in 3D for printing ![]() | ||

In fact there is someone there who has a couple of stern and stem carvings... maybe available for purchase. The challenge is in building the 3D mesh (model). The learning curve is steep (almost vertical), and some of the software can be expensive. But I use an open-source (free) program that is nearly as powerful as the kind used by animation studios. Blender is an incredible tool. You can download it at blender.org. And there are tons of online tutorials there and on youtube to help get you started. I started with the cannon and achors. But will be adding parts like blocks, bells, windlasses, dcorative cavings, etc. Once the models are built, they can easily be scaled and modified to fit. I have mine posted on Shapeways so anyone can have them printed. Just let me know if you need them in a different scale. Also if you need a different size of gun/carriage, I can build the model and post them there. The online store at shapeways allows people to add on a small markup. But it isn't much. I do it for fun and the challenge - just another form of model building. I'll try building out some simple carvings and blocks next. Some of the limitations relate mainly to the thickness of the materials and the resolution of the printer. For example, Shapeways Frosted Ultra Detail material allows wall thicknesses down to 0.7mm. And free-standing wires/cylinders down to 1.0mm. So with the swivel guns at 1/72 scale, I couldn't include the handles as they would have been too thin. And on the gun carriages, I had to lay the rings flat against the sides as they would have been to small and thin to print as anything more than surface detail. Shapeways can print these in a range of different material including bronze, gold, and silver. But different materials mave different limitations. Right now I'm working on making 1/72 deadeyes, blocks, and other fitting for the Hannah. But If there is any interest, I can make some test pieces at more common scales for the members here to test out. What would you think would make good test that most of here could use? A 16-lb long gun and carriage from 1812 era? at 1/4"=1'? Let me know what you guys think... | ||

Sculpted figures are much harder. But I enjoy the challenge in learning new techniques. And 3D printing is fascinating. I may try some belaying pins and other finicky small parts as well. I may even try using it to print frames or moulds for building ships boats on. Maybe there is a way to put up a survey to see what parts and scale folks here would be most interested in. | ||

Plastic printed parts are not (yet) as smooth as molded plastic or metal parts. But it does provide modelers with ability to manufacture custom small parts in quantity. In some cases it's possible to make parts that cant be made in any other way. But at the end of the day, if I wanted to build a plastic model, it would be cheaper and far easier to buy one of the many kits available. I just see 3D Printing as a way to make parts that I just cant easily. Like miniature cannon barrels. And really tiny parts like the 1/72 scale swivel guns. And quite possibly ornate stern carvings... I just haven't developed microscopic carving skills like the master builders on this site. I'm always in awe of their craft. And I much prefer the look of a hand crafted wooden ship to a plastic model any day. [ Edited Wed Oct 23 2013, 10:55am ] | ||

But I have to do more research on the different crew members' uniforms. The rough first draft below looks more like a Canadian Mounty or old Boy Scout leader than it does a colonial sailor. But the technique should work once I get the proper style worked out.![]() | ||
