Tenacious 3D Printer Flexible 405nm UV-Curing Resin with High Impact Resistance Standard Photopolymer Resin for LCD DLP 3D Printing (1000g, Clear)

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 for some tabletop miniature making and it's alright. I mean, I haven't printed straight tenacious, so I can't attest for how strong it is by itself. Paying ~$70 dollars for a liter of this and then ~$70 on two liters of elegoo standard makes it around $47 dollars a liter of the mix. and for that, it isn't so bad! The (very thin, because we're talking about 28mm miniatures) swords now don't break as easy! They still would break in a drop if it landed on it, but you now don't break the sword (as often, anything is possible) when it catches on your sleeve! I can't recommend anything lower than a 33% content of Tenacious because then they swords will be closer to regular resin, and at that point, you're just wasting expensive resin for nothing. Swords and staves still break on drops with 33%, arms take some heavy throwing to break, and then to get the waistline to snap on a Gandalf miniature I printed, I had to STOMP him 7 times!!! Which is much better than regular Elegoo! Overall, it's still more durable however you look at it, and for getting strength for as low as $47, I think it's worth it!!!! But, if you plan on painting the models, probably use 50% or more tenacious so that they don't break as often!

I decided to give this resin a shot after I saw a couple YouTube videos using this mixed with other resins to create stronger parts. It definitely works well for this. I have found that a 10 part Elegoo ABS like resin to 1 part tenacious gets a great print that is much less likely to break if it falls off a table. Very handy for DnD figures. The only downside to this is that it has an extremely strong odor. You will not want to use this in your house unless you are able to vent straight outside. This isn't jusy a set a fan in the window type of smell. I added 4inch ducting with an inline fan to a vent leading outside to my printer so I can continue to use this without having to move it to the garage.

I used to only use Elegoo's ABS-Like Grey Resin. Occasionally, I would get portions of my prints that seemed to have partially cured resin on them, mainly on flat and outer surfaces. This would happen on two of my printers rather often. At first, I thought it was an exposure issue, however, after trying various exposure levels, it would still happen! I heard about Siraya Tech's resin line through a Facebook 3d printing group for Warhammer. Namely, people would mix about 70-80% of their Fast resin with 20-30% of their Tenacious resin. I knew I had to give this a try. The day I switch to Siraya Tech's resins, I had ZERO issues printing. It seemed like my prints were sticking better to the build plate, needed less exposure time, had more detail, and had virtually zero support failures. Now I know that I'll never switch back from Siraya Tech. I highly recommend this product, as well as their other products, not only for the quality, but also the consistency. Also, if you are printing small miniatures with breakable parts, this is absolutely the resin for you. You can flex this stuff like crazy without breaking it.

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 flexible resin IS flexible if printed thin. If you're printing thinner than about 1/4" the print remains flexible after curing. You do not want to hollow the model though or the outer shell may collapse. It is also VERY messy to clean up. The resin is like motor oil mixed with honey, it's very slippery but at the same time it's sticky. It's thicker than most other resins I've used and it does not take detail as well. If you print something like a print in place octopus or shark the print WILL break at the joints within a few bends, but if you print something normal, it will be durable and flexible. I also tried mixing this resin with eSun general purpose resin and their tough and strong resin and had very good results. The resulting print retained some flexibility but was also stronger.

Muy buen producto la ocupo como aditivo para hacer más resistentes las resinas cotidianas una mezcla del 15% mejora muchísimo la resistencia de las resinas normales

I ordered this resin for its flexibility but I found that is not flexible. It is tough but with very low flexibility.

Ik mix dit door mijn "normale" resin heen. 15% tenecious en 85% normaal zodat mijn prints minder broos zijn. Enige minpunt is de prijs

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.

So, first off....not like the description. It's not rubber or flexible. I printed a tire for an rc car as test.... It was warm and alittle flexible right out of the maskine but after washing and curing it became hard. It's so hard that I could bang on it with a hammer and it wouldn't break, pretty impressive. I am now trying to print with a mix of 10% of this to see if it can be used as an additive to strengthen other prints, as some people has suggested.
