This is a relaunch of the project that failed to fund a few days ago, they're trying reducing the cost and relying on people picking up more kits overall to make the numbers work (1600 rather than 1200 kits). I hope it works
(3D print to show size)
OK, since the sculpting part of my Tycho AFV is done, I'm continuing the rest of the build here. If you want to see the modeling and printing portion of the Tycho, go here:
I'm building this vehicle as a light tank for use with my NOVA Corp soldiers. First off, if you haven't read the sculpting thread, here's what the Tycho looks like. The 80010 NOVA Corp Sgt standing next to it has just been selected as the tank commander:
I haven't been designing models for 3d Printing for very long, but I have already gotten in the habit of creating my designs to use small pilot holes and small pieces of raw filament to align and pin pieces together:
I basically glue the filament in one side, and trim to fit into the other side. Then test fit, and glue.
The two turret halves went together the same way. Unfortunately for him, my NOVA Sgt had to sacrifice his legs to become a tank commander.
However, it's much easier for him to fit in his tank this way:
Next up was the first round of sanding. As you can see, the print has lots of ridges. The camera really magnifies them, though - they're actually 0.15 mm apart, and they feel a lot smoother than they look. After the first bit of sanding, I did some gap filling, and filled in a couple of holes I decided not to use because they got support material stuck in them. Next up will be a light sanding of the filler (Pro-Create) and then a coat of automotive spray primer, followed by more sanding.
And here's what it looked like when I called it for the evening:
Rocky and Bullwinkle naming aside, this is the truck. I originally started building it as a follow up to the death dumpster, but it fit together neatly enough I decided to see how it looked without orking it up. I still haven't decided if I want to clean it up and gap fill, or add a bunch of plates bolts and teef.
Been working on a few big stompy robot designs since June, with an eye towards making my own independent faction for CAV, but also making them generic enough to be used elsewhere. This is the first one I've picked to work up fully as a ReaperCon entry, and be printable from a more-or-less standard 3D printer. The thing I've found is that curved shapes in the vertical axis really don't look that good. Too many "steps" as the shape is sliced into flat slivers. So, the trick was to print all the curves and other angled items along the plane of the print bed. Here's what the CAD looks like (PTC Creo Elements Direct Modeling Express 6.0).
Each color is just making it visibly separate from the adjoining pieces, and doesn't mean anything once it is printed, as you can see all the blue pieces below. It's not all of the parts, since I forgot to take the picture of the other lower half.
But, it is now all glued together, and some of the very flat parts were sanded smooth. I set out with the concept to also include some standard modelling items, so the barrel of the gun is a 5/32" (3.97mm) brass rod. I've got a couple of other ideas on some other little battle bots that use common items too... I just need to figure out what those common items could be.
First shot shows the crewed side of the upper body. The gun itself is centered over the legs, and it is currently modeled in a split leg configuration. I've got it worked up that it can stand on two legs, as shown in the CAD render above. All that would need to be done is to swap out some short pegs that pin the joints together with some longer ones that go through both leg pieces, just for alignment and stability.
Then here it is from the other side. This contains a fully decorative block of pieces, and the above shot shows a little block of deco as well. My intention is that should I keep making these, I can "upgrade" the later vehicles with missels, gun turrets, electronic suites, and other little fiddly bits. So this would equate to a Pre-Production Vehicle. Fully functional, but not something that'll be sent out and mass produced.
One final shot to show the size comparison with a Spectre CAV that I've painted up before. I'm a little worried about how big of a base it'll have to be placed on, but then again, it's in a firing stance, and that's just how big it'll be.
I've got the entire figure now drying from the slathering in acrylic gesso, which I'm using as part primer and part gap filler. Not something that would normally be used, but due to the nature of 3D printing, I believe it does well. I did do a couple test pieces back at the first of the month, and found a lot of modelling issues, but felt that the gesso worked rather well for what I wanted it to do. The plastic parts quite often had small gaps where it didn't fill in all the way, which I later changed in a couple small pieces to be 100% infilled internal spaces rather than the default 15%.
I'll wait for everything to dry, then give it a good sanding. I might do a second coat as well, I'm not sure, but I really like how it came together. That is, once I got some epoxy glue that would actually work.
