Siraya Tech Tenacious Highly Flexible 3D Printer Resin, Flex Black, 1kg

Absolute must for making minis. I recommend mixing this with a tough or abs-like mix at around 85% abs to 15% tenacious. Solid resin with amazing clarity of detail. My models are able to bend beyond normal constraints and fear of dropping and breaking are almost absent.

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 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'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.

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.

This stuff is excellent. Mixed with my normal resin at 20% and results are almost plastic like in flexibility. Have to say this is a must have for resin printing.

Wow! Incredible resinPaired with the siraya fep film I am getting cleaner looking, crisper prints with less warpingBang for your buck!

Excellent product and service

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

メーカーが二年以内に使えとHPに書いている商品にもかかわらず、一年半以上前の製造品が送られてくる。

I've been mixing 80% Fast/20% Tenacious for a few years now, with the correct settings it's the best Quality prints I've ever had.
