Those look like some very nicely-shaped parts Anon. The hips part especially has a great form. Nice mons, nice bunns, good overall design. I'd like to see a collage of several angles to judge these a little better too.
Yep, 3D printing takes time especially if it's one of the lower-end ones like mine is. There are little infill tricks and tips for making printing speed trade-offs. Remember you're a prototype maker, a frontiersman. It's naturally going to be taking you (and all the rest of us) several tries to get designs worked out and tweaked fully. That's why prototyping stages are basically always more expensive than final production. Keep this in mind and try to be patient.
Remember, a future anon who takes a fancy to your designs and decides he's like to use your
particular robowaifu project, will have relatively smooth-sailing, since you've already borne all the design headaches for him and other ahead of time!
I think if you'll attempt to use triangles
(not just deltoid or any other angles) in your bamboo frame designs, you'll be shocked to discover just how strong it actually is. Remember: all 3 edges need to be securely fastened together at their vertex points. This is what makes a space frame out of it (look the term up).
As far as a roribot goes, do what you want. It's an engineering challenge, and one that's well-known. The Square-Cube Law
bends it's knee to no man, same as all the laws of physics too. While you're in the prototyping phases -- particularly to keep testing costs down -- I'd actually suggest you specifically work on a 1m robowaifu prototype. Smaller is much cheaper and faster, and it's why toy manufacturers basically always have lower overheads than real hardware manufacturers.
Just stay aware that the smaller design is just a prototype, and you won't be allowed to market anything that looks childlike to the average boomer eyes.
Good luck Anon, you've already come well along in my opinion. Keep it up! :^)
