Siraya Tech Tenacious 3D Printer Flexible 405nm UV-Curing Resin with High Impact Resistance Standard Photopolymer Resin for LCD DLP 3D Printing and 8K Capable (1kg, Obsidian Black)

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.

Good resin. Easy to print with, very flexible.

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 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.

Not the easiest resin to print with but it is nice to have around. I needed it for it's unique hardness qualities and though it's didn't prove to be as flexible as I had hoped, it was still the most flexible resin I had ever used within the cheapest options I had to choose from. I'm not planning on buying this item again, but if a situation arises I know that I can still trust it to print without too much headache.

Printed quick and easily on my Saturn S4 U, and had a nice flexibility to it when cured at room temp, but when cured in 60C water the hardness increases, and barely has any flex to it. It has a nice rigidity with enough elasticity which seems like it will resist shatter when under stress. Feels like it rivals Siraya Tech's Blu Nylon Black when it's been heat cured, which could make it a good value alternative. Has a nice transparent smoky blueish purple color.

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

Would be unfair to rate this lower because I DID have some issues, however that's because I use this resin a little differently than what's recommended. Overall it's very good. It prints easily and is quite flexible. I purchased this to mix in with an ABS like resin for mini printing. My main problem with the cheaper resins is that they're super brittle and easy to break off things like arms and swords. Introducing some flex resin helps to solve this, however the flex resin is very expensive. I had a look online and saw a few people recommend a mixture of the two to save costs, and its worked out very well for me. The prints are flawless. It also helps if you get 3D designs made by a pro! Anyway, the issue I had was with a very large hollow piece. After printing, and curing, the piece started to warp and crack on the outside, while in the inside remained semi flexible. Now this could either be due to improper mixing, or more likely, uneven curing, since I couldn't get the UV inside to cure the interior or the object. The outside was likely OVER cured too. Only 1 part of about 20 for this model turned out like this and it was the first one printed. Everything else since has been flawless. Mixing them works so well I will continue to do so until prices of model specific resins drop... hopefully.
