eSun Standard vs Hard-Tough resin - mechanical tests

[@dpanayotv90]

Thank you for making these videos!

[@Maxlr2005]

Thanks for the test! , It is really helpful

[@EngineeringAfterHours]

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 so much, just what i need before i decide.

[@alext1006]

Thanks for your efforts

[@matop2000]

Very informative, thank you

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 :)

[@alycapo3391]

Liked and shared, looking forwards to the Esun Abs plus and potentially the Esun CF nylon

[@Ridgerunner2270]

Nice, and informative video. Thank you.

[@srijantanwar3245]

thanks for new video

[@sarcosmic-]

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?

[@pk6336158]

Same thing I realized, I ordered 2 x Siraya Blu then saw this video and cancelled my order.

[@RCProCars]

Очень ценное видео! Жаль что крайне мало лайков и просмотров ((( !!!! Спасибо за огромную работу! Это очень помогает!

[@michaellopez6123]

have you done a test with creality resin? Regards

[@MyTechFun]

Not yet, but Creality already contacted me too, they will send some resin for testing.. but probably after new year.

[@bodgab1]

Szia, sütötted 50fokon 20 percig UV curing után hard tough-t?

[@MyTechFun]

Én csak kaptam a resin próbatesteket, de nem hiszem, hogy ilyet csináltak

[@Ryxxi_makes]

can you test esun nylon carbon fiber filaments please

[@MyTechFun]

I have PC and Nylon too from eSun (no CF yet, but it will be tested too)

[@pk6336158]

How to get esun nylon,carbon fiber or high temp resin?

[@mesutsomuncuoglu695]

Did you post process hard-tough according to manufacturers recommendation? Water curing + 50'C oven curing for 20min?

[@MyTechFun]

I am not sure, these specimens are printed for me by two different persons. But they are pro, so if it is officially recommended, it is done.

[@educationaltechnology8363]

How esun performs compared to other brands

[@MyTechFun]

Few weeks ago I tested Elegoo water washable and Prusa Tough resin (you can download result in pdf too). And in week or two I will test Siraya Blu, tenacious and 50-50% mix

[@mrnlce7939]

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]

Good thinking. I should test that

[@claystudiofx]

Are all you esun resin doesn't have expiration label on the packaging ? I bought couple of esun, i only see " EXP : 12 months" printed on the bottle, but no production or expiration dates. How about you ?

[@MyTechFun]

It has manufacturing date.

[@RioElMystic-999]

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.

[@MyTechFun]

I had an experiment with mixing resins, added Tenacious to Blu kzbin.info/www/bejne/faLFkGB_frOSd68 Maybe later I will be back to these type of testing..

[@flaguser4196]

Thanks! So scientific and informative! I wonder how useful a durometer (type D) would be for similar tests (I'm trying to achieve a certain flexibility).

[@MyTechFun]

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.

[@flaguser4196]

@@MyTechFun cool! i ordered cheapo ones and waiting for them to arrive. it might not be very good for absolute measurements, but i'll try to get the same readings from reference materials (which i'm not allowed to break :-) ).

[@MyTechFun]

@@flaguser4196 If you have experience, what do you think, what type is better for 3D printed plastic? HD or HA www.banggood.com/0-100-HA-HD-HC-Digital-Shore-Durometer-Sclerometer-Rubber-Hardness-Tester-Meter-Paragraph-Tire-Plastic-Rubber-Test-Tool-p-1806123.html?cur_warehouse=CN&ID=514829&rmmds=search

[@flaguser4196]

@@MyTechFun I'm still exploring myself and waiting to get my hands dirty as things arrive. 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.

[@vassoritzen]

Is the same dimentions of fdm tests?

[@MyTechFun]

Yes, test specimens have same dimensions

[@zdog90210]

thanks for this video im making rc car wheels that will take a torque force and a axial force so strong it is so it bends

[@samjohnson3124]

kinda funny to see, its kind of a good approximation, though I think a polar-radial degree chart would be better

[@youngster30uk]

I also watched your video in siraya blu, if I am reading the results correctly, even esun standard resin significantly beats siraya on every test. Is that correct?

[@MyTechFun]

Yes. Results are compatible, I left the conclusions to viewers. Correct

[@youngster30uk]

@@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

[@jordyv.703]

@@youngster30uk I think Siruya is more scratch resistant and is harder, not necessarily tougher.

[@japanfilling]

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 .

[@adirachman8069]

maybe you must try this product: Nylon-Green Tough by Phrozen for your Hard & Tough resin test..

[@rvent3605]

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.

[@paulblythe5899]

Just ordered some to try out... what per layer time are you using, please. eSun recommend 8sec, but don't specify RGB or Mono screen.

[@angrymobstergoon]

There was no compression test, which I think where the tough resin will shine

[@poojantanawala3979]

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

[@pavano6970]

What printer do you have? I am currently using monocure tough resin. It's good but a bit brittle. Anycubic is good actually.

[@pk6336158]

This video was amazing, can you try the Jamg He Art Engineering, Jamg He High Tenacity Resin and Jamg He Engineering Pro resins? The Jamg He Art Engineering resin claims to have an impact resistance of 460J/M and the Jamg He High Tenacity Resin claims to have an impact strength of 736J/M !? 😶🤨 For reference, can aluminium, copper and or brass be compared to your test in the videos so the viewers or I can compare it to an item that the viewer or I may have at home to relate easily to🤷‍♂.
