Siraya TechBlu 3D Printer Tough Resin with High Toughness Resolution Strong and Precise 3D Printing 405nm UV-Curing Rapid Resin for LCD DLP 8K 3D Printer (1kg, Clear V2)

Updated 2: Tried Tough Clear, and I am impressed. Has good strength with decent flexibly. It is nice and clear, but does have a yellow hue. Even after following their blog post about heat treating in 60C water for 10-20min then sitting in the sun for 30 min. The clear isn't crystal clear, but clear enough for what I'd doing.Updated: Wish there was a separate review for each Blu resin, as each one has its own quirks and features. I finally got the nylon mecha to print what I wanted, and I think my issues coincided with software and hardware updates to the slicer and printer. Blu Lava Black came out great, and looks really promising for some applications I want to try and use it for. The print came out great, and dried/heat treated at 65C for 20min, then water cured for 10min. Part looks great semi-matte black finish.Blue Nylon Black has a bit of a bluish color to it. Made some lids, handles, and few other things with it, and has printed great every time I've used it. Has good impact strength, and should handle accidental falls of 3-4 feet no problem from parts I've performed drop tests on.I have had nothing but great experiences with Siraya Tech's filament and resins, and I haven't had a single failure while using any of their resins, until this one. A whole bottle, and not a single successful print. Used on a Saturn 4 Ultra using Siraya Tech's provided profiles for this printer, but I just getting failures in ways I've never seen. The failed parts that did come out look great, and surface finish as well the scratch resistant properties of the resin are really good. Just wish I would have actually had a working part after spending $70 and wasting 3 days. This stuff is thick and messy, with a lot of residual resin getting left behind, so make sure you clean well after using. Not a user friendly resin from this experience. That being said, this stuff is strong! I am really impressed with the strength of the parts I have made with this resin.

I can't sing the praises of this resin enough. Not only does it print beautifully, but you can get all the details you'd ever want just by being careful with your layer exposure settings (< time = more details).You can get any amount of flexibility/hardness depending on the amount of time spent curing.5 minutes or less of curing, and it's so flexible that it's basically a nylon. 5 to 10 minutes of curing it's not nearly as flexible, it gets harder but still doesn't break easily.It took me 30 minutes of curing to get it to a point where I could snap off supports with my fingers; anything less than that, a good pair of toenail clippers will be required.Ideal print settings on a Creality HALOT MAGE (regular, not pro) are 0.25mm layer size. 1s light delay. 2 - 3s per layer with 3 to 5 bottom layers at 10 to 30s, depending on the weight of the model.At 10s, you can easily just tug firmly, and it comes right off the build plate. At 30s, I was using a metal spatula and a rubber hammer to get it off, (it still didn't break, but I did have to completely realign my print head).If you want a really cool effect, mix this 50/50 with the Sunlu "abs-like" resins in blue or red.It also mixes so well with other resins. It's my go-to resin to fix other resins. I even used this to fix the super crappy Yousu silver resin.I wish I could buy this stuff by the drum.Long story short, this is the best resin I've ever tried, and completely worth the money.*I use the AnyCubic Wash and Cure 3 for curing, but you can also cure in direct sunlight, and the properties get really interesting.

This is the best resin I've used so far. Any issues I've had with it are from my own lack of knowledge in 3d printing. It's sturdy, you can paint with inks over it and make lightsabers and fire and stuff. All in all, it's pretty great.

I've been resin printing since 2017, using a Qidi S-Box (largest MSLA print at the time for under $1000), and since mid summer of that year, I started using Siraya Tech resins.I've used other brands, like anycubic, Elegoo, and bunch of other brands.But eventually I end up coming back to Siraya Tech, the quality of resin for the price is really good.Over the years I've used Tenacious, Blu original, Build Smoky Black, and many others.But recently this past month, I bought a Elegoo Saturn 4 ultra, and it's been since March of 2024 that I made my last resin print. So I wanted to see what Siraya Tech had to offer lately, and saw a sale on the Blue Tough Easy Grey.And I have to say, the stock resin profiles on the Siraya Tech website for the Saturn 4 ultra have been really great! I thought I would have to spend hours tweaking profiles to get perfect prints. But I just had to load the stock profiles and go, which is something I'm not use to. It even makes really decent prints on the Elegoo high speed mode.As far as odor,it's not that bad compared to other resins I've used, your still notice it but it's not a really strong smell.Toughness, I've been using it to prototype linear screw drives, and it has been holding up pretty well, I'm not 100% on the wear resistance.But either way, I'm like always, pleased with the quality and price of Siraya Tech products, so I end up buying 4Kgs of resin during their sale, used up 700Mls so far
