Siraya Tech Fast ABS-Like 3D Printer Resin 405nm UV-Curing Non-Brittle High Precision 3D Printing Liquid Standard Photopolymer Resin for LCD DLP 3D Printing(Grey, 1kg)

This was the first resin I started using with my Creality resin printer and it worked well but I wanted to try some others. I tried both Longer and Anycubic resins that were also rigid-type resins. With those I had issues with these resins not reproducing detail as well as the Siraya resin and also with them being more brittle such that the parts shattered easily when trying to remove them from the build plate. I tried adjusting the initial layer settings on the Longer and Anycubic resins but then had issues with them coming detached from the build plate during printing. When they did stick, the resulting prints showed deformations in areas of fine detail. So, I went back to the Siraya resin and these problems went away and I started getting near perfect prints once again. One thing I did find is that the parts need to be cleaned in fresh alcohol so when I print multiple pieces in a single print, my procedure is to do an initial wash in an alcohol bath using a chip brush to remove the uncured surface resin. I place each part on a drying rack until all parts have received this initial treatment. Then because the second and subsequent parts had been washed in the alcohol that contains some of the washed off resin, I will do a second wash in a fresh batch of alcohol on all of the parts (except the first one cleaned). Then I use a hair dryer on the high setting to thoroughly dry all of the parts. Lastly, I cure all the parts in a UV chamber (cardboard box lined with foil) for 10-15 minutes on each side. I dont think over-curing in UV is an issue as I have accidently left a part in the chamber for about 12 hours without any ill effects. For settings, I am following the recommended settings shown in the spreadsheet from Sirayas website. I couldnt find any similar instructions for the Longer or Anycubic resins which is another reason that I dont care for these other manufacturers. One thing I would like to see is for Siraya to offer their resins in larger sizes such as gallon or 4L containers as long as this would not adversely affect shipping costs.

Im in the middle of an engineering project (basically a custom RC plane), and needed some small, precise parts that still need to take decently significant loads. Of course print quality and resolution is a more a matter of what printer you have, but I can say this stuff printed fantastically on my Photon Mono S with the settings recommended by Siraya Tech (you can find a spreadsheet on their website). The parts that I got are incredibly strong. I know this is an ABS-like filament, but Ive legitimately gotten better performance out of these than actual ABS from an FDM printer. That is most likely because printing orientation does not matter nearly as much, so the parts turn out mostly isotropic (equal strength in all directions). Ill describe some of the cases I used this for below. MY USE CASES: One of the parts was a stepper motor gear (28BYJ-48) that needed to deal with up to 0.1N*m of torque. I can tell after a lot of use, the section that meshes with the stepper pin has worn down from perfectly tight, to having maybe 3-5 degrees of slack, but its still perfectly usable. Many of the parts require linkages between them, so I printed 5mm pins. In my case, I had to reduce the size of the pins to about 95% to avoid clearance issues, but once they were in place the pins had very little friction while still providing very tight joints. Additionally, those pins could handle a surprising amount of shear force. I tested with a 5kg weight, so statically thats about 2.5MPa, but I also drop tested with that rig, so it could have easily reached 25MPa at one point. CLEANING: Specifically regarding this resin, you have to empty and clean your vat within 2 days if you dont plan on printing again. This stuff will separate into layers in about that time and becomes harder to clean off the vat. Also, water curing has yielded good results for me. If youve never resin printed before this part is for you, otherwise move along: Cleaning the prints is quite a hassle. They come out coated in liquid uncured resin which is, in the case of this resin, definitely a nasty skin irritant and potentially toxic if ingested (most resins are). Youll need LOTS of isopropyl or denatured alcohol, at least like 2 or 3 tubs or large tupperware containers, lots of paper towels, definitely more gloves than your printer comes with, and some way to get rid of the fumes. The alcohol is smelly enough, but this resin is definitely nasty stuff to be around. You have to be very careful not to get it on your skin or other surfaces (as it is quite drippy off the printer). With this resin, I got the best results by cleaning with alcohol from a spray bottle, then rinsing in water for 30 seconds, and then submerging in a cleaner tub of water before leaving in the sun (for 45 minutes) or shining with a bright UV light (1 minute or more, flipping the part with tweezers). I tend to keep one tupperware container for the alcohol cleaning process, which is very thick with uncured resin, one container for dirty rinse water, and one for clean water (and a bonus extra container to place all my contaminated tools and paper towels). I can usually run with this setup for several prints without changing out the liquids, which is nice because you CANNOT wash this stuff down the drain (unless you want even more micro-plastics in the ocean), and it absolutely has to be cured before you dispose of it. I typically save my 2-liter bottles and old mouthwash bottles, dump everything into those, and leave them out in the sun for a day before putting in the trash. CONCLUSION: If you can deal with the hassle of cleaning and PROPERLY discarding of the waste, then this resin produces results that you simply cannot get with other printing methods. Sure, FDM printing is less toxic and usually easier to get larger prints with, but the precision and speed of resin printing is unmatched. Usually that comes at the cost of poor physical proteries, but with this resin, you can get really small, precise parts with fantastic physical properties.

Im pretty new to resin printing and Ive tried 5 different resins from different brands so far. This Sirayatech fast grey is far stronger and more flexible than the basic resins Ive used. The drawback to this is it can be a bit more difficult to remove supports, and must be printed with slower lift speeds than Ive achieved with other resins, its worth it for the added strength though. Holds detail very well, not quite as good as phrozen 4k, but better than Anycubic standard and standard+. For reference my perfect setting for accuracy on a photon M3 is 40um layer height 1.8s exposure, 3/3mm lift height 40/80mm/m lift speed, 80/40mm/m retract speed. 4 burn in layers at 24s exposure. Im working my way up on speeds, Im sure I can print faster, but the 180-240mm/s I was using with the phrozen resin failed and Ive only validated this one at slow speeds so far.

I got the metal gray as it showed that it was darker than the navy gray, but mine is much lighter like the regular gray. Other than that, I’ve purchased quite a few colors of this specific resin and they’re all amazing quality, super high detail, and prints quick

Okay so now that I have gone through about 4-5 bottles I can say with confidence that this is the best budget-friendly resin on the market. I almost never have failed prints, the quality is always great and overall, I am just so pleased with this product. Using the settings I use on my Elegoo Mars 2 Pro I get perfect prints every time. I am not the best painter but you can see the detail in the tentacle of the second bust. I included my perfect print settings to help others who may struggle.

I have been using the smoky black resin mixed with some Anycubic clear for about a year , it’s the best thing I have found , it makes the prints not nearly as brittle and I don’t have to expose them to a bunch of light . My mix ration is about 60% clear Anycubic to 40% of the siraya tech . It’s saves some money and just plain works for me . I mainly use mono x 4K and 6k printers but I don’t think it makes a difference that I have seen between printer makes/models . So happy I found this stuff , before using this my prints would break if I just looked at them wrong, much less knocking one over on a counter or shelf. Happy Printing !

Excellent resin for 3D Printing!

This resin is absolutely superb. I undertook a challenging 3D print job that consisted of very large pieces that needed precision to with interlocking gasket faces to be assembled. I tried several resins, but I was encountering multiple issues that resulted in print failures: separation from supports, drooping and distortion from the build plate, warping and bowing of the sides, and pitting from shrinkage. Basically nothing was turning out properly to my liking, and to get it even close required laying out a dense forest of supports just to get each print to hold on. And the stuff was soft and scratched easily even after curing. I switched to the Siraya Tech smoky black and the results are like night and day. Ive had virtually zero warping and distortion, and parts are fitting together with precision that exceeded my wildest expectations. Ive had zero print failures, and even am using significantly lower density of supports, which both saves on resin, and post print cleanup. In terms of cleanup, the resin sands, files, and polishes nicely, and the translucent color helps a bit with dry fitting prints. Id recommend wet sanding in order to keep down on dust. After curing, the resin is sturdy and decently scratch-resistant. It feels something similar to Lego plastic. Surface takes primer and paint well. Printing on a Saturn 2, exposure calibration was a breeze (2.5 seconds). Additionally with the plug-in air filter, and odor is minimal.

I did not expect this to be this good... Im going to order more and maybe try the grey/navy grey

Updated after I received the bad bottle. It was replaced for free and Ive purchased a couple since with 0 leaks. AMAZING! ***Well this resin was recommended by a source so I went with it. I have painted many miniatures for him that were printed with this resin and I really liked the way they came out. So I ordered myself a bottle and it is fantastic resin. My issue is that when I ordered the second bottle, it arrived with a broken seal and most of the contents had leaked out into the product box. What. A. Mess. I am not going to bomb this product with a 1 star review because the resin really is fantastic if youre ready to flip a coin on whether or not youll receive any lol. It is also worth nothing, that the bottle caps on the bottles were both different, so my guess is perhaps I received one bottle with a new cap design (youll find many other reviews here stating they also received leaky bottles) and one bottle with the old cap design. The one non leaky bottle I got came fully in tact and in perfect condition, filled to the top with that sweet, sweet grey wizard juice. Overall, Id say that my experience was isolated and Amazon will happily refund me or exchange the resin at no cost to me. TL;DR - Fantastic resin, poor packaging on old bottles that causes leaking, but there are new bottle caps that keep everything in tact, just a matter of hoping you get a good bottle. :) A few tips and tricks for those new to resin: Use denatured alcohol instead of isopropyl alcohol. IPA right now is nearly impossible to find and youre limited to how much you can buy due to COVID-19. Denatured works just as well (perhaps even slightly better), it costs a bit more by volume but I havent noticed clouding in it as bad as when I tried cleaning my prints with IPA, which leads me to believe a little denatured alcohol goes a long way by comparison to IPA. With this resin Ive only really needed to cure with UV for about 5 minutes on most miniatures Ive printed, any longer and it tends to start getting brittle. In a test where I exposed the resin to 18 hours of direct UV contact, there was no discoloration.
