Siraya Tech Simple V2 Aqua Gray Resin - Water Washable 3D Printer Resin - Precise Detail, Low Odor, Easy to Print, Non-Brittle, for MSLA, LCD, DLP 3D Printers - Easy to Clean 3D Printing Liquid 1kg

[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.

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.

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.

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.

The media could not be loaded.  This is the best performing (and best looking) resin I've used so far. It's a very thin watery consistency that picks up very intricate details and cures very well. Buy it and try it!

Prints really clean out of the vat, but once cleaned in alcohol and cured it gets cloudy and yellow for a few days before the yellow fades back to near clear. I bet I could get rid of the surface level cloudyness with a cleaning/finishing solution

I really feel I am getting the best prints I have ever gotten out of my Elegoo Mars. I am also able to trim down the exposure time by .5-1 second, depending on the layer thickness, so that speeds up printing for me. It cleans up really easy, but I think 15% alcohol might be a bit conservative.And due to a super low viscosity, it drains off really well when you let your build palte sit at an angle for a while to drain off excess resin. I go with a 50% alcohol mix, swish around in bath 1 for about 20 seconds, then move to bath 2 for a 20 second swish and it is cleaned perfectly. I find I do not have to brush or scrub any areas to remove any resin. It really does help extend the life of my alcohol with the clean draining and lower % alcohol needed.I am not really looking to print much at all in a translucent black/grey, so I add just a bit of any other type of white or grey resin to the bottle, just enough to make it a bit more opaque and this works great. This may slightly affect the alcohol % to clean, but not enough to worry about. I keep to a slightly short post-print cure so my pieces are not super brittle and I am really happy with the results I get.The only caution I have is your printed piece will be very susceptible to moisture damage, so do not overly soak your piece, this also applies even after curing, so do not also excess moisture to collect. Painting with usual acrylic paints is no issue and it paints up great.

Got good results with 12sec/2.75sec cure time. Wash with watered down Dawn Dish soap and you won't have any slime stickiness on the surface. Cure as required.

Incredible product. Had a few issues with settings on my printer but Siraya Tech Support was able to sort me out. 10/10 customer service.

Each resin brand, line, and even bottle behaves differently. I found this one is more fragile when curing because it actually prints with better accuracy than another brand of water-washable that I tried - so I found problems in my STL designs, fixed them, and this resin handles it better than ever.The advice given for my printer on exposure times by the brand is way off, so you'll need to fine tune.It seems to smell slightly less and react to the heat less with less fumes than another brand I tried.

I have previously used Elegoo water washable resin with good results. However the prints are a bit brittle and Sirayatec resin is supposed to be more durable.First, let me state that the prints are good, I have had no issues and the resin prints about 20% faster and seems more durable. However the prints remain tacky and smelly after cleaning and curing. I washed them again and cured them longer with no success. I tried to find an answer online, but all I could find was that the resin was maybe not properly mixed. So for the next print I shook the bottle for a minute before pouring the resin, but with the same result. Even after priming the prints remain tacky for weeks. Today I tried washing the prints in alcohol after washing with water but before curing and they turned out great. I then washed the prints I had primed earlier in the alcohol and the primer came off, after that they were not tacky at all.In conclusion this is a great resin for printing, but it needs to be washed with alcohol. You can do the rough cleaning with water but you need to finish with alcohol. Since I specifically wanted a water washable resin I'm disappointed.

He probado por primera vez esta marca de resina es Grey V2 , se supone que es lavable al agua, ni agua caliente ni fria... SE LIMPIA CON ALCOHOL y HUELE MUY FUERTE , con mi Saturn 2 necesita 3s de exposición pero bueno... Me decepciona que diga que es lavable al agua cuando no es....-1° Foto es lavada con agua.-2° Resina directamente en agua caliente como recomienda el fabricante.-3° lavada con alcohol.
