Blu 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)

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.

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

This resin paired with my Elite designs from Lyles3DPrinting (L3dP Garage) is an absolute winning combination. The detail, strength, and surface finish come out exactly how these parts were engineered to perform. Printed on the Elegoo Saturn 4 16K, the results are consistently professional-grade. If you’re chasing precision, reliability, and top-tier output, I highly recommend both this resin and this printer. Built to perform. Printed to dominate. 🏁 -Lyles

I got a bottle of Blu (clear) v2 because of a recommendation on Zack Freedman's youtube channel. He used Blu to build high impact parts for a nerf blaster and found it was the only resin that didn't break in stress testing. Having just tested my first parts off the plate with it, I can confirm that it is ridiculously tough. Most resins, when printed in a cube or brick, will either be rubber-like or shatter into ultra-brittle dust when hit with a hammer. Siraya Blu is different. It's glassy, tough, and isotropic like molded PA66 or PC. I printed Tableflip's Cones of Calibration with it, and tried to smash them with a hammer, and they took several hard blows on concrete. I am going to try printing a pneumatic manifold and burst testing it just to find the limit of this resin. The downside is a loss of X/Y precision due to some light bleed and a rather difficult washing process. I find there's about 0.2mm of additional scum on top of walls that isn't quite cured, but doesn't quite wash off. This might be a problem with my old FEP film, I'll have to compare to a fresh one eventually. For now, a little extra scrubbing is acceptable.

Always good resin. Worth every nickel.

I buy this resin frequently so I bought one for a later project. Got this March 20 and today April 24 is the project day. I couldn't for the life of me figure out why it wont print. I spend money changing the fep, changing the screen protector which is also more money, empty the vat and cleaned it about 3 times and so many more things, strained it then I finally read the box and it expired last year October, well away from when I ordered it. I wasted allot of money. I learned my lesson but I should have not gotten a 6 month old bottle in the first place

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.

Nice
