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)

This resin is much less viscous and sticky than my printer's brand of transparent resin. For this reason, I can reduce the exposure times and get a cleaner looking print. The resin drips and washes off better too. I do wish they could create a clear resin in their ABS fast line, but others get around that by adding tenacious to it, which I have not yet tried. Clear resins don't stay clear after washing and curing UNLESS extra steps and products are taken/used, but there are videos out there that explain how to do this.

Super easy to use. The setting presets on Siraya Tech's website took a lot of the guesswork out and I've been pleased with the results.

Low odour, easy to clean

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.

Not only does it not smell bad but easy cleanup as well, I have tried a few dif resins and have found out this by far works awesome even when temperatures change within 20 degrees. It does NOT affect the print in any way, started printing in 74 degree ac quit while I was away came back at 83 degrees and it looked just as good as it did at 74. Was very impressed no loss of detail nor did it lose printing qualities. A++

Great detail and no failures since I switched to Siraya Tech Simple.

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.

[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.

Update: After burning through an entire bottle and a half of this material and messing with different settings, I think I've figured it out. I'm bumping it up to 4 stars for this reason. The issue I was having with this was that I was washing it for too long before curing it. I find if you put this into a water/alcohol solution for more than 2-3 minutes, it basically makes the entire print rubber and incredibly difficult to work with.I bought this more expensive "water washable" resin as it claims to be non brittle, well, that isn't the case. Printed off a test miniature model from One Page Rules (Gator) and just the same as with the Elegoo water washable, which is a lot cheaper by the way, it snapped effortlessly with basically no bend at all. The resin itself is great, if you don't need any flex, but if you need something that isn't too brittle look elsewhere. It's a little bit better than the Elegoo in that regard, but it's a lot more money. I'm also having an issue with some kind of black substance floating around in the resin as well, I have to filter the entire bottle every print out of the vat and back into the vat to try to keep it out, whatever it is. I find this product to be basically worthless for minis, I just had 3/10 minis snap while removing the supports. When printing the supports are so flimsy they actually move around and I've noticed that they keep fusing to the model, where they shouldn't even be touching the model at all.Won't be buying this ever again, I only wish I didn't get two bottles.

Best resin i used ever! very liquid and very easy to warm it up since its viscosity is to light.Didn't have any fail in more than 3L printing.Great Resin

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.

Resin prints great but warping during cures, need to follow instructions to us 15% alcohol for best results as using water causes some parts to get brittle when not dried

Items supplied asper description. Will update after testing in the printer
