Hey guys, this is still very much a work in progress, but I need some advice! I'm making a dragon doll and I've sculpted some elastic ball joints for its legs. There is also a top part to this leg which is not pictured. Anyway, I was wondering if you think using the 3D print on the actual doll would be strong and durable enough to do? I kind of dread the thought of moulding and casting these (there are holes running through the inside of the top and bottom part of the leg to allow for the elastic).
My question: what resin is strong enough to be able to use this as is without moulding and casting? And any advice on painting/pigmenting the resins?
EDIT: I'm using a Photon!
Thanks! Hope everyone is safe and well!:)

Any ABS-like resin would do fine I think
?

Great! Any in particular that you'd recommend for the Photon?

I have only used elegoo ABS-like grey, I’m very pleased with that one

One thing folks have done with similar dolls in brittle material is to not make the bar from (in this case) 3d printed resin but instead leave or drill a hole and insert a very strong wire- basically a small metal bar epoxied into place so you can stri
ng quite tightly for good posing, but without any worry you're going to break the bar.
I'd print from a material as close to the finished colour as you can and then paint with model paints or excellent quality acrylic and use a sealant, avoiding painting the ball joints if you can (as it will tend to chip and flake with wear). Check out some of the awesome full repaints of Monster High dolls on Youtube for inspiration. I highly recommend this channel:

Okay thank you! I will have a look:)

A mix of resins might be in order, here. Siraya Tenacious mixed with an ABS-like resin should do the trick.

Oh fantastic! Thank you so much for all this!

Fantastic, thank you so much for the advice!:)

You may have to experiment a bit with ratios...usually not a straight 50:50 mix. And exposure times will be different, too. Run your exposure test on any mix you settle on before printing.

Awesome, thanks for the tip:)

What sort of range of movement do you want from your BJD? If you only want limited posing, light stringing and a little experimenting with exposure times would be worth the time.
Verity Filipow

Moderate to limited posing. It's for a client, and I've stressed that these things are fragile and mainly for display only!
Kat Schulz-Booth
2020-03-26 20:05:59
Then I would play with the wall thickness and exposure times. Which resin do you normally use?

I'm a fan of ApplyLabWork mSLA grey resin. It has twice the tensile strength than Anycubic and equivalent resins.

Currently still getting through the anycubic green I have but willing to switch!

As stated above: Anycubic Resin is not good for tensile use.

A lot of people have been printing the bjd dragon from myminifactory. They hold up pretty good from what I've been told. Gonna try printing my own when the resin gets here.
Kat Schulz-Booth

Give the green a go...will the BJD be painted? If so, just go with the resin you're use to, if it holds up strength-wise.

Yes, I've printed dolls just fine and they last and Havent broken

Do you have a different brand you'd recommend instead?
Verity Filipow
2020-03-27 18:10:31
Which resin were you using?
Neal Conway
2020-03-27 18:24:53
Not that I've used but people on the Internet seem to recommend Siraya Blu as being one of the better ones.
Siraya claims to have printed a hook with it and hung a 20kg off it, summat you definitely couldn't do with the Anycubic Basic . . .
t's fairly expensive, though, at $50.00+ IF you can find it.

2020-03-27 18:25:36
Yeesh, okay. I'll have a look, maybe I'll find some over here in the UK. Thanks!:)

Ah, I'm UK too. Ebay sellers are knocking it out @ £50... for 500ml!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Holy shit! I've just had a look... so insane.. I think I'll try an ABS like resin. Maybe that's a better shot right now.
Jamie Masotti

I have been using elegoo ABS like resin
Verity Filipow
2020-03-28 22:29:08
Sorry just saw this. Yes, I'll be painting it. I'm going to try that elegoo abs like grey, as that's closer to the actual painted colour anyway!

Good luck! And let me know how you go? BJDs are a hobby for me and if I can make it cheaper, yay.
