Parts too tiny?
Omg Ipledreamer this is what we have been waiting for! Please keep going!
I had to reorder filament. Funny thing: similar problem as when ordering BJD parts, which are from the same company, but ordered at different times. That stuff also varies from batch to batch. The one I got now is clearly lighter/a tad pinker.
So there will be some color variation within the body parts. Oh well, I can live with that. I want to paint him anyways, so it is just important that the filament beneath somewhat matches the colour used.
Right now, the chest part is printing, Four parts...ugh. All the separations for the rest is also done so far. You clearly need a really capable computer for that kind of stuff.

I have seen this
I am sorry, I cannot read this. Can anybody please translate it into English?
Well, I printed out the final part of the horse's neck. I was clever enough to print the pieces in such a way that the part is checkered:
That is no biggie, as I will paint the whole horse anyways.
@Ipledreamer , Is it hard to sand those? Maybe a thin putty coating would help? Gosh it's really getting exciting! What type of primer/paint do you plan on using?
When the model glue has fully dried, my husband suggested to mill a groove along the seamlines. As I also have 3d printing pen (yes, I had to have one of those as well), I can then fill in this groove with PLA filament. This will result in some type of plastic welding, which will strengthen these weak spots a bit more. After all, I am afraid that I will have to use really strong elastic to avoid sagging of the middle part.
For a primer I think I will use some clear, matte hardware store stuff I also use for faceups?
There is always also wiring??? For the middle, or, depending on size, a wood dowel? You might need a primer first for paint to stick, but I have no idea about that plastic and how well it takes to paint. Might want to experiment He's going to be the coolest horse ever!!!
Well, I do not sand the overall surface, as due to 3D-printing, it has some grip to it. What my husband suggested: when the model glue is fully dry, I will make a very small groove along the seams, to make them little bit deepr and wider. This groove will be filled with PLA coming out of a 3D printing pen (yes, I had to have one of those as well). That way, some kind of welding is achieved.
When that is done, I will have to sand the welding marks. PLA itself is pretty soft, but you have to be careful not trying to use too much torque on the Dremel. When the torque is too high, the material will just melt and create some nasty plastic, which has to be sanded again. You really don't want that.
All of that is theory by now. I think I will grab some trash PLA pieces and try it first there. Just to see if it a) works at all and b) if you get really and kind of advantage.
You mean a wood dowel through the body? I do not want to do that, as the body is jointed. For a support, it would also not be ideal. I might have to come up with something adjustable, to accomodate for jumping and rearing poses (if it can do that, I do not know yet).
But let's not take one step ahead of another. I really have to concentrate at what I am doing right now. Otherwise, this won't get finished (and I am famous for that).
Here you can see the full horse in a smaller size:
Looks nice, but sadly there are several constructional issues:
a) I had to install with my 3D-Pen several stop spots at hips and knees. Otherwise, it would buckle permanently (we know that problem, don't we?).
b) The construction of the hindlegs looks nice, but as it is only attached by elastics to the center, there is a serious downfall. The back center shows a clear tendency of sagging.
Ergo: No way a big BJD can sit on the horse as-is. I have to do some serious surgery of the horse's derriere in Blender.
I will also still enlarge the hooves and lift the last section of the neck by adding some material. That way, the whole neck will lift a bit. I think it looks a bit too short for the massive body.
On a more positive note, here are picture of the head and neck, including the jointed ears:
Maybe its because I'm looking on a desktop, but I cannot see your pics, @Ipledreamer. Otherwise, it sounds like you're doing pretty well so far.
That is strange. I can see pics. I am using picr.
I don't know what my desktop did, but now the pics are showing up.
Your horse looks pretty darn cool! How big is this one, it looks like it could hold a 1/4th BJD.
The white one is about the size of a Breyer horse. That means, much too small for an MSD.
The larger one, which will become a golden dun, will hopefully be tall enough for a 70 cm doll.
The horse is AMAZING! I think I meant a wood dowel if a heavy wire wouldn't work. Would sanding to smooth some of the joints be do-able? I don't think they're bad myself, is that what you were talking about wanting to fix?
Wow, the horse looks already great!
Certainly it'll look really awesome in the end.
No, with 3D-printed pieces you have to be super careful with sanding. It is not full material like resin (there sanding is no problem). With 3D printed parts, only the surface is solid. The rest is infill, which means the inside is a funny pattern stabilizing the whole thing (you can at 100 %, but then parts get really heavy). So if you sand too much, the pattern will show.
But I have to put together the big parts, because a 3D printer can only print certain dimensions. So the very big parts (out of which the body is composed) have to be split, printed in parts, and then glued together again. So there are seams, which are very visible. And I think it will look much better if these are filled in with something - ideally with the same filament as the stuff out which they are printed. This is what I do with my 3D pen (it is a 3Dissimo, which has several bits similar to a Dremel).
And no, you do not want to smooth the joints. They are much more slippery than resin joints, so I will rather suede them.
To be honest, if a nice, well-constructed resin BJD horse for 70cm guys existed...oh well, I think I would spend the money (and I am sorry, I know that there was Domuya Nightmare. Not my cup of tea).
Thanks for all the updates, this process has been really interesting to watch.
After seeing this, I’m now wanting a large horse myself, and I don’t have an SD. @Ipledreamer thank you for sharing your process. Maybe you could do a project journal? Just a suggestion, no pressure. I’d really like to see your horse and what you do to fix the issues you come across while making it. I love your project journals! So informative!
