Siraya Tech Simple 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 (Grey, 1kg)

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.

Good stuff. Effective and precise prints. Only defects in prints are due to cheap photon zero printer quality. Shake, pour, print, clean (alcohol only!), Cure, done. It's that easy.Once cleaned* and cured it was slightly tacky and flexible. Withstood a drop from about 4 feet. Overall very happy with the quality and price.*Do not clean with water. Move from printer to alcohol solution immediately. Cleaned in 80% alcohol solution without problems.

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

The media could not be loaded. This resin does polish up very nicely however it is brittle and not very durable. Corners easily chip off. But despite that it is really easy to work with. It is cleaned up nicely with a little IPA in water.The standard profile of settings was good for my Mars 4 9k Ultra with just a few exposure tweaks. It sands pretty well but is a little soft and easy to sand off numbers or fine details. Again it does polish nicely.It does Inhibit platinum cure silicone, even the Siraya Defiant silicone.All in all it is really clear with some polishing and works for what I need, However I will be getting A different type of resin when this runs out.

[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.

This resin works great with my Elegoo printer.

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.
