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

This resin is xlnt and prints beautifully with the correct settings. One thing to note is this resin needs to be used at least 26Deg Celsius for best results. At first I tried it and room temperature was 22 deg and I got bad cracks and layer separation. Then I bought a resin printer heater and set it to 27 deg c and let the resin in the vat and the printer warm up for 30 minutes then printed and then everything was perfect with no setting changed beside the temperature. Strong with a little bit of flex. Odor is I would say medium compared to others, It's not odorless but also not strong as well. So I would say medium-low odor compared to other resins so all in all very good. Sirayas stock settings work well on the MONO M7.

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!

Mix about 25% of this into some ABS-like goop for some nice, high quality resin. Or use it directly for even nicer quality resin.

I'm experimenting around with some new resins, and this stuff so far has been extremely easy to work with. The settings provided by Sirayatech worked with minimal, if any tweaking and I've not had any failures since I started, they seem a lot more durable than the previous resin I was using as well. Only thing is that I didn't care for was that it wasn't as flexible as I liked, so currently I'm trying to mix with Sirayatech flexible to get results I'm happier with. The only things I noted that aren't a real issue to me, is the odor seems to be a bit stronger than the other resins I've used, but I keep my printer out in the garage so this isn't really an issue to me. It was a darker gray as well than what I was expecting going off the picture, but that makes no impact to me personally. I'd recommend giving it a shot, so far I've been getting a lot of mileage out of this resin.

If you're reading this review you probably already know what this is and what it does. Tenacious resin is flexible when cured in a 3D printer. That means you can blend it in with other resins to add some flexibility and make brittle prints a little more durable. You'll lose a little detail, but that's better than snapping all the small parts off your miniatures. The more tenacious you add, the more flex you get. You can print pure tenacious, I've never done it though. One thing to keep in mind, Tenacious doesn't like cold temperatures, so at a minimum make sure you start printing with a warm room. The UV curing releases heat so you usually can count on that to keep the vat warm enough to print, but if you're getting failure, that's a good place to start looking for answers.

Super durable, flexible, without loss of detail. I mixed it with a ABS like resin to reduce the price.

Wow! Incredible resin Paired with the siraya fep film I am getting cleaner looking, crisper prints with less warping Bang for your buck!

Ottima resina gommosa. Quello che cercavo. Semplicemente spettacolare

je l'utilise pour renforcer pour les pièces de jeu la siraya navy grey, à hauteur de 10% . Mélange bien connu et très fiable, une base pour les amateurs de figurines de jeu

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.

Quite possibly the worst resin I've ever used, so bad that I ended up pouring the remaining 85% of it in to a large vat & curing it all before disposing of responsibly. I was quite excited to give this resin a go & expected good things in the hope it'd be a cheaper replacement for the Phrozen RPG resin i currently use. Lots of vigorous shaking to make sure it was well mixed & in to the vat which raised its temperature to what is recommended. Spent a couple of hours calibrating the resin to my printer (Elegoo Saturn 4 16k Ultra) & then ran a set of prints through it which were duplicates to ones I currently hold in stock (Phrozen RPG). Washed & cured the finished prints which had a glossy finish to them, almost translucent at the thinner parts, the detail was ok but nothing compared to what you get using Phrozen RPG resin. There's hardly any "flex" in the cured resin but probably just about enough to prevent easy snapping points of limbs. When I cleaned out the vat I found thick congealed resin as I poured it back in to the bottle, had almost runny jelly consistency to it along with some very thin cured strips. A very odd experience with this resin throughout , I wont be wasting my valuable time or money with it again. I gave it two stars as it did print to an ok-ish standard but certainly not of a good enough standard to sell via Etsy etc... I've added four images, two are using Tenacious & the other two are printed using Phrozen RPG.
