Tenacious Resin with High Impact Resistance
Before Printing:
It is a good practice to mix resin and expose the bottom of the vat to air before printing. This replenish oxygen in the vat and helps reduce peel force.
It would also ensure print consistency if user can get the initial resin temperature above 25 and keep the environmental temperature above 20 C.
Recommend best support settings:
Tenacious has the most impact resistance of all the Siraya Tech resins and thus has the most flexibility. This means it likes thicker support to print well. Depending on the printer, you may want to check out the Blu recommended support setting as a starting point. It is best to print no less than 80um for this resin.
Before Printingsure print consistency if user can get the initial resin temperature above 25 and keep the environmental temperature above 20 C
Tenacious Support recommendation:
Tenacious has the more flexibility of all our resins Make sure the support tip diameter is 1.2mm for larger prints with a depth of 0.5mm
Siraya Tech - Tenacious
A Flexible and Highly Impact Resistant Resin
Are you looking for a resin that has great flexibility, strong with impact resistance?
Then this is the resin for you.
A thin object printed in Tenacious can be bent 180 degree without shattering while thicker object shows great strength and resilience. The transparent light yellow color makes it easy to check for the internal structure of a print and easy to dye.
Feature
- High Impact Resistance
- Flexible
- High Toughness
- This resin is best when used with high quality FEP film based vat.
High Toughness and High Impact Resistance
Tenacious 3D printer resin has high toughness and high impact resistance.
Its extremely high toughness allows the printed thin objects to be bent 180° without breaking. And you can increase the toughness and durability of fragile standard resins by mixing them with other resins.
Tips:
(1)Cleaning:
Use a painter brush (or any brush made with hair) remove excess resins on the printed part with Use 95% concentrated Ethanol (preferred) or IPA to clean. Some form of methnol should work but make sure it does not contain acetone. Do not submerge the parts in alcohol for more than 30 seconds. After 2-3 minutes of cleaning action, remove alcohol with a hair dryer or air blower. For complex part with lots cavities, it may be a good idea to clean/dry multiple times. User can check by touching the dried surface of the part to see if it is still sticky. If the dried surface is still sticky, wash some more and dry again.
(2)Post Curing:
Tenacious reached its optimal strength when the printed part is post-cured with UV after cleaned. Use 395-405nm UV light and cure for about 25 minutes. Make sure resin is completely cleaned off and there is not alcohol left on the print before curing. Curing by submerging object in water will significantly increase curing efficiency.
Due to the high percentage of polymer, it is recommended to print Tenacious at temperature 25C or above, a heater is not required. Please refer to the user guide for more detail.

It wasn't obvious to me that the Easy Grey Tenacious has different properties and cure times than the other Tenacious colors, because they're all sold under the name "Tenacious." I wish it were stated clearly, because I wasted quite a bit of resin trying to troubleshoot. I had read so many reviews about people mixing Siraya's Tenacious with their Fast resin (or other brand resins), so I was confused that adding Tenacious Easy Grey to my Fast resin didn't make any difference in durability. I decided to try printing with just the Easy Grey (not mixing it with any other resin) and followed the curing guide for Tenacious on Siraya's site... which says to cure Tenacious prints for 25 minutes (!). That seemed crazy to me, but I prefer to test manufacturer guidelines before experimenting. There was no alternative cure time for the Easy Grey. Unsurprisingly, the prints were extremely brittle and broke with the tiniest bit of pressure. I E-mailed Siraya about it and they said:"First, Tenacious Easy Grey is not exactly the same as Tenacious Clear. It is easier to print and has excellent flexibility compared to standard model resins. But it is not more flexible and stronger than Tenacious Clear.Second, Tenacious Easy Grey is engineered for high impact resistance, ensuring models are both flexible and durable, so you don't need to mix it with Fast Grey because it has better mechanical properties.For the issue you mentioned, you can try to reduce the curing time to 10 minutes because the smaller model requires less curing time. If the curing time is too long, it will get hard."I don't understand why Siraya doesn't clearly outline the different properties and cure times between the different Tenacious colors. Or just market the Easy Grey as its own line. It would be very easy for them to clarify it up front, and it would save their customers money and frustration.

Okay I have a Saturn 4 Ultra. The reality for me is that when I calibrate I find that my build plate has hot spots and cold spots. What I mean by that is that this device self levels and even with that, with most other resins I can see a difference depending on where the model is printed on the plate. The difference is small but it is there. Not with this resin. Yes I have a tank heater as well. This resin behaved exactly the same all across the plate and I dialed in and printed the miniatures above.What I noticed is that quality was "good" but not perfect. The Elegoo 8k resin has a better detail by a small amount BUT in my case the flail kept breaking. We may be a bit rough with the mini's as when we are done we just put them all together in a small box. Just doing that broke the flail multiple times.What I noticed is that before I could probably bend that flail around 10 degrees before it would break. Granted I never tried but this is my estimate as I could feel it about to break. With this resin? I was about 25 to 30 degrees before I felt it was pushing it. For me that is huge.Now as others have said, you don't mix this resin as it is already mixed. This is the grey resin and not the clear tough resin.If this resin was say 25% cheaper, this probably would be my main resin as I main print miniatures. Because it is so expensive, it will only be used in rare situations or mini's that we use a lot.

This resin isn't rubbery. Let's get that out of the way first off. It's not like printing with NinjaFlex on an FDM printer. Parts that are made with this resin will deform, but it takes a little effort, and they go back into shape, but it takes a little time. They are more like soft plastic than rubber. But that deformation and give makes them incredibly strong and able to withstand heavy impacts. This would be a great material for outer casings or bumpers or tubes that needed to have some give to them. Resin from resins printers is often really brittle, and this can be added to some other resins to make them much more usable and less liable to break. You don't have to print with 100% Tenacious (although the items I've posted above are), as you can mix it in to add impact resistance to other resins -- and that's really where its primary value lies. Alone, it's a kind of whitish/clear resin that's not clear enough to be see through, but not opaque enough to be white. It's a bit soft, so it can scratch relatively easily. It doesn't yellow heavily, but it's more the colour of 'natural' PLA filament. It also has a kind of strange refractive colour that looks very blue to purple in daylight. I'm not sure what causes that, but it's interesting.Overall, though, I'm super pleased with this resin. It's a great addition to the arsenal of Siraya resins (Blu being the one I use most, followed by Sculpt and Tenacious in a head to head with both of them being more commonly used as additives to other resins for my stuff). It's a spectacular flexible resin for the price.

I bought this item to use in a mix with the standard version of this resin in order to give a little flexibility to my prints. The flexibility that this resin gives to the prints is amazing, I no longer have to grit my teeth every time I accidentally drop one of my prints. Also while using it in a 80|20 mix I don't just burn through the more expensive resin and still get quality prints for my printer. The only reason I give it 4 stars is because the level of detail that the print gets with this resin is somewhat diminished, but it's a pretty fair trade with not having rigidness of the standard resin.

This is some really amazing resin by itself. but the cost makes it Really expensive to just use on it's own. I mainly use this as a additive to my Siraya tech fast grey. this makes my D&D and war gaming mini's super durable, this also will help supports way stronger and will actually result in less failures as well, just keep in mind that you will have to do test prints to make sure it's just right or you will have a really bad time removing supports because of overexposure. I use a 15% mix to volume. so if you have a brand new 1000ml bottle of siraya tech fast, just put in 150ml and it will be just right.

Ich habe das Flex Resin zu 1/4 mit dem ABS like Resin des gleichen Herstellers gemixt. Ich experimentiere damit Kettengeflecht/ Chainmail zu drucken. Wer hätte gedacht das es mit Resin geht.Außergewöhnlich - hält gut und ist flexibelJe nach dem wie man es mixt kann es auch sehr flexibel seinGanz klar - Next Level Resultate
