Siraya Tech Tenacious 3D Printer Resin Flexible 405nm UV-Curing Resin with High Impact Resistance Standard Photopolymer Resin for LCD DLP 3D Printing

Bought 3d printer and all accessories of which this is one for my son he is really pleased with the results so it’s five star rating from me

After purchasing two different colours I checked the Siraya Tech website for data sheets and realised that the different colours are actually different products which fall under the Tenacious label.Easy grey and navy are 73 shore D - Think ABS plastic or very hard rubber.Clear and obsidian black are 65 shore D harness - Think shopping cart wheel.Flex black is 70 shore A - Think shoe sole.By sheer luck I needed to print parts and flexible and hard prototypes and the two resins I've bought are flex black and clear, so no money wasted and the prints came out fine. Getting the softer material off my flexible print plate was a bit of a task but a sharp scraper did the job.

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.
