Siraya TechSimple Water Washable 3D Printer Resin - Low Odor, Easy to Print, High Precision 405nm LCD UV-Curing Aqua Resin - Ideal for 8K Capable LCD, DLP 3D Printers - Tough and Clear (1kg)

I’ve been a loyal return user of the original water washable resin from this. Company for a couple years now. I decided to try this V2 version for something different.Great choice. It seems to pick up more detail than the previous version, and the darker color helps in verifying how the print came out before committing primer to it.Interesting thing is even after curing in the UV chamber there is still a rubbery feeling to the print almost as if it isn’t cured. But it is and feels very strong.I’ve returned a couple times here to purchase more. I like it.

I was a little skeptical at first because it is so thin when poured but it prints really good.

This resin works great with my Elegoo printer.

The resin works great, used the same print settings as Siraya Tech Fast Grey and it worked flawlessly printing a base and some small test symbols, cleaning it i basically first cleaned it with just water, removed the supports then used 99% IPA on a large paintbrush to remove remaining resin, did 2 passes IPA then water.The thing i wasn't sure about was curing, i plan on painting it with transparent resin and need to fill the drain holes first but if you cure it with a UV lamp it will yellow so i printed several bases.Each with it's own curing process, the first i didn't bother curing but on all of my bases i noticed it would start to inflate at the bottom and slightly warp so i used a hair drier to heat it up and pushed it back in and it sort of worked. I think it warps like that when it's not cured and once it cures it gets back to it's original shape. A big issue is that if u leave it without curing it can take weeks to fully cure, so i basically cured it 7 min on one side and 10 min upside down, it would yellow a bit but using a hairdryer removes some of the yellowing and it will disappear after days\weeks almost completely.The warping issues is most likely due to how i modeled the base, think it's best used on small fully solid objects instead of large hollow objects but it works regardless.

Siraya tech never fail to me,.. I use other brands before but that one is really good.!! Clean results and the cure is excellent!.. I’ll recommend,.. make sure when ad resin specifications, download the community specs results,..( users of Lychi Slicer) that give you the best exposure time for your printer.

Haven't had any issues with it and it seems to print well. I use an elegoo Saturn (and at one point the original Mars) and I haven't had any issues with it. printed many minis and dice masters with it. good product. It does have a resin smell though I'm unsure if there is any 3d printer resin that doesn't though.

[EDIT Aug 24, 2020I have several prints from around the time of my initial review (July 8). For this test I printed 3 models with each resin mix: 100% Simple, Simple mixed with 30% Blu and mixed with 50% Blu. All were washed in 99% isopropyl alcohol, 20% iso and 35% vodka then rinsed with tap water and cured with a UV lamp. To date I've had zero issues with "melting" as others have reported. I used the same settings as I do for Blu (which come from the Anycubic Photon Google Sheet that is available in a number of enthusiasts groups).The 100% Simple is about as brittle as other standard resins, subjectively. The 50% mix was a little sticky after the wash/rinse for non-99% iso washes, and I didn't notice a significant difference in subjective toughness compared with the 30% mix. I did notice a marked increase in smell as I increased the quantity of Blu. ]I am a fan of the Siraya Blu and when I heard about Simple I had to find out if the low odor and clean up with 15% alcohol claims were true. I was too excited to try this and loaded up a model that has settings for Blu without really thinking about it, and Simple printed beautifully. I also found that the smell was hardly noticeable.I put the prints in my ultrasonic cleaner with an approx 20% IPA solution and cleaned them for three minutes. I was very pleased that there wasn't any obvious resin on the surface. Blu, on the other hand frequently felt gummy despite being cleaned with 99% IPA. While removing the supports they felt stiffer and more brittle than with Blu, but this resin isn't claiming to be tough.I'm going to try mixing this with Blu to see if it gains flexibility while retaining its low viscosity and easy clean up.

Hooo boy, yeah, I'm gonna buy more of this stuff.A friend gifted me a new ANYCUBIC Photon. I originally picked up 500ml of the ELEGOO clear. Now, I'm not a long time pro in resin printing. But somehow I feel like the calibration print test that comes with the printer should result in a mucked up FEP liner. Half the prints stuck to the bed liner and I wound up poking a hole due to aggressive scraping. My bad. But c'mon.Swapped out the FEP, tried out some 3-in-one PTFE lube on the vat floor, just in case. Ran the test print and what a difference. Now, the print time wound up being comparable to the ELEGOO clear, about 17 seconds. But the prints showed minor differences between lengths of 9-17 seconds. Even the bad prints looked okay, and didn't stick to and destroy the FEP. The properly cured samples are pretty gorgeous. Getting ready to test it with a more intricate print, but I'm already sold on this stuff. And can I just say, the label looked so generic to me I didn't expect to find any info on cure times. Nope, I was wrong, their site has GREAT data on their various types of resins. Can't wait to sample the others!I haven't tasted the resin, so I don't know what it pairs with. If that happens I'll update.
