What resin for tracks ?

What resin are you using when SLA printing tracks ?
I have been experimenting with mixing regular Anycubic resin with Siraya tech Tenacious to a 2:1 ratio hoping to get the strength of the regular resin with a little flexibility of the Tenacious to hopefully stopping it from shattering so easily.
Difference between 1/16 and 1/14 tracks.

I have printed a bunch of tracks in Sunlu Toughness resin. Been running them on my 1/16th Kranvagn extensively and haven't broken one yet. They are pretty flexible yet strong.

Tracks look good, better than printed in plastic. Is it for Panzer III/IV?
I usually mix Siraya Build with Bly Nylon as 3 parts to 1 part first, and add 10% of Tenacious (1 to 10 of the total mix) as a second.
I wasn't sure about tracks in resin because under some heat and load I'm having results like this.

Thanks for the reply's,
The tracks are for a upcoming T62 1/14 build , i won't be worrying about the parts warping with the heat, i live in Ireland , it never gets that warm, would be more worried about how they would cope with water.

I'm living in the middle of New Zealand's South Island, it's not too hot here either, especially in winter
Wonderfully understated there mate.
Brass Monkey springs to mind !!

Interesting video from Derek with Siraya resines tests for strength and flexibility. It seems like Build is the best overall for tracks, maybe with just a bit of Tenacious.

Before I respond...Disclaimer: I am no expert on resin printing. I'm just saying what my experience is with various resins.
I've watched most of these Siraya Tech vids and even bought Blue, Tenacious, and the Build resins to do some testing with. I've tried Siraya Tech resins both with Tenacious and without. With Tenacious, the dimensional accuracy wasn't great on my Anycubic Photon M3. Without Tenacious, the supports were very hard to remove. After curing, the support sanding was worse than with Sunlu Toughness. The price of the Siraya resins are also really expensive comparatively. I'm not a fan of having to custom mix paint or resin to get results I need as to me the results end up with an amount of variation from batch to batch. The Build/Tenacious/Blu mix I used was strong until the track twisted. Then the track would break.
I find the Sunlu Toughness soft to sand, able to twist without breaking (within reason), and strong enough not to have the pins pull through.

Thanks, ive never tried the Sunlu resin before, ill have to look into it.
