Siraya Tech Tenacious Flex 3D Printer More Flexible 405nm UV-Curing Resin with Faster Rebound High Impact Resistance High Precision Tough Standard Resin for LCD DLP 3D Printing (1kg, Flex Black)

When printing alone with it, it resembles a very very soft rubber, almost like a rubber band. Geometry is important when printing with the resin alone because it’s so soft, supports will deform. I needed it to be more rigid so I combined it with any cubic black tough resin in a 3-1 ratio. The parts come out as a semi soft TPU and they do not break. I really like this resin. Do not buy any other flexible resins. They all fail

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.

While it's way too expensive to use on its own, I mix this ~1:4 with Sunlu Plant-Based and the results are incredible. Small thin parts bend over 45 degrees without snapping, and I can drop prints from standing height onto tile floor with no breaking. I print a lot of spindly miniatures and am quite clumsy, and this resin is quite literally a game changer.

This is a must-have for me now. I mix it with Anycubic ABS-LIKE Pro 2, with fantastic result. No more brittle parts that break, now they bend a little and snap back. Great for minis.

good resin as additive for others to make them more flexible - using by itself not good for my applicationbut adding to other resins like ABS like or standard make them less fragile and prone to crackingbut itself too sticky ( hard to take off the build plate )

I often use this in an 80/20% mix with 80% Siraya Tech Fast to give it impact resistance and flexibility. Your exposure and curing times will need dialing in, as the material changes its properties quite a bit. Once you've got your settings in order this stuff is a breeze to work with. When used straight, the strength and flexibility are impressive. If nothing else, I'll always have a bottle around to toughen up brittle materials. I haven't tried it yet, but I'm curious how this would work as a surface treatment.

Not as flexible as TPU but it is tuff like it. It will not break. Seems to print nice, this is the first print with it

Me gusta el producto sobre todo por el respaldo de la marca, en su web están los parámetros para cada tipo de impresora y eso ayuda mucho

Bought this originally as an additive for model prints. But recently had to print some structural braces with a little flex so experimented with this. I am seriously impressed. My end product could hold substantial weight ( pair of synthesizers) and was flexible enough that solid prints wouldn't chip or break even when hammered. Bougt another bottle immediately. Highly recommend for anyone making parts that need to resist wear and stress.

Es una resina negra pero muy traslúcida,su uso principal era para hacer llantas 1:64 las cuales salen muy transparentes, si la quieres para eso mejor compra otra resina, al lavar las impresiones no debes dejarlas más de 5 minutos en el alcohol, lo absorbe muy rápido y se quiebran las piezas, el empaque no tiene un parámetro de exposición aproximado y su soporte técnico no es muy bueno.

Muy cara, pero mezclandola con otras resinas (10-12% de esta, el resto resina normal), mejora flexibilidad y resistencia sin afectar los detalles de forma evidente

Sulla confezione non si riporta ne data di produzione ne numero di lotto, sul sito siraya tech indicano 6 mesi di scadenza me è possibile? Resina tendente al giallo.

Genauso wie es sein soll. Würde es jederzeit wieder kaufen.
