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

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

I wanted a flexible resin to solve a problem. Boy, is this flexible. Press it hard and it flexes. It does take a while to recover if the part has thick walls, but it does recover. I tested its strength by whacking it hard, repeatedly, with a hammer, and I am sure I could hear it just laugh. I couldn't break it. Then I printed the part with walls 0.4mm thick and squeezed it and flexed it. It took quite an effort to get one wall to crack, so I'm happy that it is both flexible and durable. It is not straightforward getting the printed part off the build plate. I use a flexible plate, but when I flex the plate, the printed part just flexes too. Reach for the very sharp spatula. Pity about the price. Pity the Black colour is not readily available. I found the 'clear' cures with a slightly yellow tint (as stated by the manufacturer). I recommend this resin if you need some flexibility and resilience.

Just bought this clear resin and I’m really disappointed by its shore hardness. I’ve printed both Obsidian Black and the softer Flex Black and was impressed by both of those. The clear resin is almost solid. I’m wondering if I got a dodgy batch.

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

Absolute lifesaver for doping the more brittle ABS-like resins on the market. I mix it in about 20% by weight, cut exposure about 20%, and my models now bend/break like they're typical cast plastic instead of glass, with no loss in resolution.

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

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.

Love the product, I mixed with Navy Gray so that my Resin is not as brittle after cure.
