Siraya Tech Simple Water Washable 3D Printer Resin, Clear, 1kg | Low Odor, Easy to Print, High Precision 405nm UV-Curing Aqua Resin, for LCD DLP Printers

Prints great, cleans great, looks great, very durable. I was really impressed with how it *just* worked. I would give this 6 stars for "easy to clean" if I could. This is a great alternative to "water-washable" resin. Cleaned super well with only 15% Ethanol in water using only manual swishing, I didn't have to do any extra steps to make sure it was clean. It post cured *very* quickly. No smell or tacky-ness after about 30 seconds. It is very stiff (only a little flex) but is super strong rather than being brittle. I may even use this for mechanical parts that need to be rigid. Very low viscosity makes it run like water, which makes draining and cleaning way easier. The smell was very low, comparable to their "Fast" resin. The transparent-ness was great. Frosted look comes from the pixels on the screen and is solved by a clear coat. It had very little yellowing, which is excellent for a resin (additional UV exposure may cause more yellowing) Spray paint Primer adhered great, no issues. See pictures for the detail/quality of the print. Printed on Elegoo Mars, 8s exposure.

[EDIT Aug 24, 2020 I 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.

so far best resin i have worked with for minis. the main draw is it has a very mild odor and is incredibly easy to clean even with just warm water

On my elegoo mars, this Printed great with the recommended times from Siraya's web site. Didn't appear too temperature sensitive (the ambient temp was 65F). I printed three 32mm scale miniatures on the plate, and the figures came out fine, and I was able to wash them in a mix of 20% IPA (91% concentration) and 80% water, and they came out just as clean as using IPA only. After curing, they looked "frosted", but that's to be expected, no surprise or disappointment there. I believe you can get rid of that with just a quick spray of a clear coating (I'll have to try that to see) Durability-wise, the prints had no flexibility at all, but are very tough. I was able to drop the miniatures with no cracking of the major parts of the body, though small parts, like swords and spears, snapped right off since there was no flex. I could easily see replacing most of my other resins with this for day to day printing of parts that don't need to be flexible. The quick printing, and easy low-alcohol cleanup are a huge bonus. Going to try it in my Sonic Mini soon, since print times on that are 30-50% faster than the Mars or similar printers.

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.

Prints really well - I am happy with it.

I am very pleased. It doesn't smell as bad as people made it seem like. It cleans fine with 80% ethyl alcohol. It is a bit more clear than the Eryone clear. This resin is not as brittle and does have a tiny bit of flex, making it more durable to drops, damage and usability. On my list of must have. Current print settings on Photon: 13s exposure time 80s base layers lift of 1mm/1 retract 3mm/s Curing on UV light for 4 mins

It’s easy to print and clean up with water. I print windows for trains and it came out nice. I sanded the inside and out then sprayed auto detail clear coat to get the clarity.

Très bonne résine washable, facile d'accès aux débutants. Super résultat et super content, avec une saturn comme avec une Alkaid elle top.

Best value and save more money using water to wash. However need to cure for 30mins in a proper UV light curing station. My first model has crack all over. After some research, it was recommended to cure for 30mins which I only cure in a uv box for 3 mins. My 2nd attempt with 30mins curing time turn out really good, no more cracks.

Great great. Resin.

This stuff is great. It doesn't smell too much and is easy to clean up. It's a bit less brittle then other similar resins. I like it a lot.

The only issue I've had, was the provided Chitubox profile for this resin on my Elegoo Saturn 2 had too short of a layer time, causing fine-detailed parts to have repeated print failures. Otherwise it's a great product, with a mild smell when the hood is off the printer (it has an included activated charcoal filter inside). Cure-time seems rather long, and one of the details not mentioned in the description is the need to use a 15% IPA/85% water mixture for cleaning. You only read that on the SirayaTech website's spec sheet. But the resin is very liquid (at 24-25 degrees C), so you can also just let the print drip the excess and not have to worry too much about washing before curing.
