    Good video, thanks for the tests.
    The term toughness actually has a very specific scientific meaning. It's the area under the stress-strain curve. Thats why your bending test was the only one decently different...it was the only test that actually measured toughness to some degree. Toughness becomes really important when you're designing a structure that's able to absorb energy without catastrophic failure.
    Ultimate and yield strength are overrated material properties :)

    • @madthough2298

      It depends on what material you are trying to predict failure in. If the material is ductile you should be concerned with yeild strength, and uts if the material is brittle. That's why grades of structural steel are commonly labeled based on their yeild strength, because steel is a ductile material

    Thank You for doing this tests, I'm just waiting for Anycubic Photon Zero to arrive in monday. It was 99$ (clearance deals) with shipping in aliexpress, eu warehouse. Neither is mono lcd or 2k, but that doesn't really matter for my needs :)

    I was interested in the eSun hard tough and Siraya blu, and apparently the eSun resins are way more resilient. Did you found any other resin to be stronger than the eSun?

    I wonder if you add a small amount Monocure Flex 100 or some other Flexible Resin to ABS tough Resin Will it still keep strength + Ridgity + Toughness but also have some flexiblity for if you wanted to make a part like a moving gear , since it has slight bit of flex in it one wrong move in the gear wont make it shatter crazily.

      I am preparing some DIY hardness measuring system, but maybe I will invest in durometer (or maybe ask the Banggood if they want to send one for a review). Yes, measuring hardness would be interesting information too.

From what I've seen in other youtube videos the shore D scale would be more suitable for hard plastics while shore A might be more suitable for rubber-like or semi-flexible ones. Images of the shore scales showing different example objects are also really helpful.

  • @mrnlce7939
    @mrnlce7939 3 роки тому +2

    Was just wondering if the results scale evenly? i.e. if you double the thickness does it double the strength or is it that as soon a it gives in one area the whole thing fails (like a micro fracture).
    This question is for resin only as I believe it does scale fairly evenly using FDM.
    Great video. Keep it lit.

      @@MyTechFun Thanks for the reply. I am new to resin printing but am very surprised at this. Anecdotal evidence says that siraya blu is very tough and standard resins are not. I guess thats the difference between anecdotal evidence and scientific evidence. Unless standard resins are significantly tougher than most other brand standard resin. Interesting

    Did you post process the tough as esun specifies? Did the tough get baked? I print with both and the tough is noticeably tougher than the standard, much less likely to shatter and takes more strain mechanically before breaking at least in my experience my functional prints.

    Szia! Milyen hőmérsékletet bír egyébként a gyanta ? Autó alkatrész gyártására alkalmas lehet? Mi a véleményed én néztem pár ilyen ABS szerű gyantát de amig nem próbálom ki őket sajnos nem tudhatom milyen . Ami nekem kéne gyantából az olyan tulajdonságok mind a hajlíthatóság valamennyi hőállóság úgy 100C-ig és erős legyen . Ezért nézegetem ezeket az ABS szerű gyantákat csak ugye ahány márka annyi fajta tulajdonság .

    Hi, I have a question which I hope you can answer, I'm new to Resin printing and I wanna print accessories for 1/12 scale action figures, so they will be very tiny and some parts will be a thin, would you suggest the standard Esun resin for them to stay durable while using them on figures? I live in India and I don't really have any options for resin and I'm kinda sceptical about importing Resin. Please let me know
