Doll skeleton made of TPE?
Doll skeleton made of TPE?
I've been researching shore grades related to my project, the hardness of materials. There are 3 types of shore materials, Shore 00 which is ultra soft, probably ideal for internals of breasts. Shore A which is what TPE dolls are mostly made of, grade 30A I believe. But there is also Shore D which is for harder plastic, rulers and computer cases, etc.
TPE can have a hardness up to 85D, Human bones allegedly have a hardness of 90D on the shore scale. So this brings me to the question, does anyone think would it work as a skeleton material for a TPE doll? I apologize for being a bit of a mad scientist and slightly overzealous topic postings.

BINGO !!
A TPE skeleton in a hot cast TPE doll would just result in a gelatinous blob of different density TPE.
OK perhaps if the goal was a "Jabba the Hut" doll or one to simulate the blob from sci-fi movies.
Not really too good for a flexible and standing human sized sex doll.
That is one of the reasons they metal for the skeletons.
Also strength, ease of fabrication and common parts for joints and such.
Good catch.
Cheers!

Re: Doll skeleton made of TPE?
However with todays dolls the weight is primarily due to the mass of flesh material (TPE or silicone), the actual skeleton does not really weigh that much.
So a slight weight reduction due to a lighter skeleton would not be a real game changer.
Light weight is a positive for CF, but its cost compared to steel is still high. While lighter than steel, CF has some issues with strength and occasional brittleness. This can be overcome with sheets having the fibers in alternate orientations, but might be a challenge for tube structures for a skeleton. One big issue is that there tends to be some weakness issues at the point where it bonds to other materials, say where a pivot for a knee would be attached to a tube for a leg.
CF has a lot of good points and is a good material, but maybe not for a doll skeleton.
Sort of like it might be fine for an airplane part, but we did see recently that is does not work too well for submersibles.
Cheers!

In terms of strength though, I would think that shouldn't be an issue, at least if they were made right. At least based on articles like this: http://melbournehipsurgeon.com.au/carbo ... hopaedics/
And you're right, a carbon fibre may be achievable but wind up costing as much as the whole doll. At which point you have to ask whether it's worth it. You can source it (even as a hobbyist) fairly cheaply in a variety of shapes and sizes. eg: https://www.supercheaphobbies.com.au/st ... 72_77.html but it's still probably more expensive than the comparable steel tubing. And that's not counting assembly.
Maybe one day I'll bite the bullet and have a crack at making one myself.

Most of the innovations have been started by folks who are intrigued by finding the solution and cost does not really factor in.
So if cost is not an option , then anything is possible! We even put a man on the moon once.
Skeleton improvements seem to occur slowly for the doll. Probably since they are the last visible item of the doll.
We did get to almost universal standing foot plates, then better joints, then EVO, gear stuff, hinged wrists, and now articulated fingers.
So improvements are slowly chugging along.
Right now the issue is probably cost. Both for the material and that their trained (?!) group of fabrication folks are metalworkers.
Tooling and training would not be insurmountable, but it would be a cost and cause some changes.
Until the manufacturers see an upside, either $$$ or bragging rights, then we will keep dealing with steel.
Just my two cents.
Cheers!

I'm not sure about the point of this.
How do you think this would help?

Good point with the stainless.chippyminton wrote: ↑Mon Oct 23, 2023 6:08 pm 318-grade stainless steel. LIght, durable, and won't rust and destroy your doll when the vaginal TPE plug falls out.
But maybe ...perhaps ... just seal the damn plug in correctly in the first place.
GRRRRR
(rant over)

It's the joints that are mild steel and rust. The skeleton is already stainless and rust resistant.chippyminton wrote: ↑Mon Oct 23, 2023 6:08 pm 318-grade stainless steel. LIght, durable, and won't rust and destroy your doll when the vaginal TPE plug falls out.
ALSO TRY Reverend Jack's Anointed Snake Oil, good for cleansing stains from the body and the Soul! Step right up folks, only $5 a bottle! We got plenty to go around! Cash only please.
