SUNLU 3D Printer Resin, 1kg Fast Curing Standard 3D Resin for LCD DLP SLA Resin 3D Printers, 395-405nm UV Light Curing 3D Printing Liquid Photopolymer Resin, Low Shrinkage, High Precision, 1000g, Grey

I used this resin in phrozen sonic, works very well on default settings. Flows well, very good resin. Ive only been 3d printing for about 2 & half months good for beginners

I wanted to get a transparent resin that was not as expensive so I wouldnt feel bad about failed prints while learning (and so i can see all the way thru the objects) & this has worked perfectly! no odor when the machine is covered by the UV hood

I notice that the resin separates easily if you leave it in the vat for any amount of time after printing. You have to mix it up before printing again. This might be caused by the temperature in my basement, which is around 68 degrees fahrenheit. The prints that I have done feel very brittle and prone to breaking/chipping, especially thinner or point parts. The quality seems comparable to the Elegoo 8K resin which costs twice the price. Overall, I prefer the Elegoo 8K resin, but Im turned off by the price. I dont think I will buy SUNLU resin next time. Ill try another brand. Printer: Elegoo Saturn 2 8K

A lot more bang for your buck

This was a mix of clear and clear blue, (imagine those rim videos where they get dipped into a solution to make an effect) but hands down, this Sunlu clear blue resin produced an amazing result. Ive used other translucent brands and typically end up with a foggy haze that takes some amount of post clean up, sanding at multiple grits and a polish to get some level of bare min clarity. This however was straight off the printer, a light alcohol spray rinse and scrub with a tooth brush and allowed it to dry in the garage for the afternoon before hitting it with a cure light for about 30 seconds on each side.. No special voodoo required, just a fantastic result with min effort.

ODOR: Much better experience with this one. With the Comgrow, I could smell it once I started going upstairs to my 3D printer room. SUNLU has a very low odor, something similar to Phrozen or Siraya Tech. Every resin has a smell, and this one is lower on the spectrum of being too much. 7/10 STATS Density- 1.11-1.15g/cm3 Bending Strength- 40- 60Mpa Viscosity- 100-300cps Tensile Strength- 30-50Mpa Hardness- 72-88D Shelf Life- Not Given Elongation- 10.002 +/- 10% Body Shrinkage- 3-5% Wavelength- 405 UV Light Printability Okay, the color is closer to a white than grey, until you cure it, then its closer to grey, but still whiter than most greys Ive used. Once this resin was dialed in with the Cones, I was down to a 1.75 second per layer cure time. After printing some models, this was adjusted to a 1.8 seconds per layer just to make sure there was enough strength between layers to prevent any separations between layers. Details are crisp and clear. Supports slip off like a dream. 9/10 Curing Time For our testing, 8-9 minutes was our standard curing time in our Anycubic Wash & Cure Plus. After curing, the resin appeared and felt solid as if the model was cast in plastic. Smooth as butter. 9/10 Dimensional Accuracy and Shrinkage For this part, we ran the new RP tester from Phrozen. I was shocked to see that everything printed, even the tiny little hairs, though, if you have meat hooks like mine and arent careful, youll snap these off, which do so, so cleanly, youll think they didnt print at all. Dimensional Accuracy before printing was spot on when measuring with calipers. Shrinkage was well within my specifications. Larger posts on the RP tester seemed unaffected, while smaller posts were accurate within 0.03mm. 9/10 FINAL THOUGHTS This really surprised us. Going into these tests, I was hopeful, but was more than willing to just let the resins speak for themselves. This one is above and beyond way better than the Comgrow resin. Low odor, no dyes that dye your IPA, Shrinkage that tests better than some of the more expensive options out there, and a cost that doesnt break the bank. They seem to have a bundle deal on their website that pushes the cost down further. If you order 5 bottles, its $99, which takes the cost down to $19.80/bottle. What I ordered from Amazon appeared to be a round bottle. What I got was closer to a flat bottle akin to an oil bottle. This was fine and reduced the form factor on my shelf. Curious though, did Amazon send me the right bottle? A damn fine alternative to more expensive options. 8/10

I purchase 5 different 1000g bottles of this resin, ALL 5 failed to print the bottom layers correctly. I tried the settings on the bottles and on Sunlus website, and all kinds of settings in between. I even contacted Sunlu and sent them screenshots of my settings and they came back with You can try setting the exposure time to 3s which is one of the settings I tried and sent them a screenshot of! SO I wrote back pointing out that I tried that, and it was in one of the photos I sent them and they wrote back The main reason may be caused by exposure time. If you need a refund, you can contact the store.! (Terrible support experience). I really wanted this resin to work, the price was right and the colors are perfect for what I wanted to use them for. I am using a Elegoo Mars 2 which I have had no problems with ever, with any resins Ive ever ordered. It looks to me like excess resin is curing beyond the models edges, I even reduced the bottom exposure times below their suggested minimum of 20 down to 10 seconds with a normal exposure down to 2s and still got the hole at the bottom of the model filled in with lumps of cured resin. UPDATE: I dont think there is anything wrong with this resin. After talking with Elegoo they explained ALL transparent resins will have anomalies like extra exposed resin beyond the boarders in Cavities, especially on the bottom layers because the light bleeds through the transparency of the resin. I tried another brand and had similar problems. However, you would think that Sunlu, being a printer and resin manufacturer would know this and explain it to me rather than throw silly suggestions out there of common things I already tried just to get rid of me. Im adding a couple more stars for the resin as it produces beautiful results as long as the bottom doesnt have cavities or you require critical specs on something like parts that require precise measurements. As far as their Tech support, dont count on it.

don;t know gave as a gift grandson says it goo resen

I started using Sunlu resin when it was relatively new on the market and I was impressed with the quality and the price. Ive been buying the 1kg grey standard resin. At the outset, I didnt need to change any exposure settings to get crisp detail and clean prints. LATELY though, I feel like the QC of the product has gone downhill quickly. Prints have been failing left, right, and center, on files Ive printed a dozen times before. Failures included failure to get good bed adhesion (yes, after leveling...), ODD failures such as the quality of the supports degrading and ripping in the middle of the supports, and peel cracks in the print where the exposed layer didnt adhere to the previously cured layers. Print detail quality is much softer when I *do* get a successful print, and it takes much longer to wash the print in IPA than it used to, even when using brand new clean IPA. And most tellingly, the IPA gets fouled a lot faster from heavy particulates. I think with some settings tweaking to increase per-layer exposure times this might be an okay resin, but when you have lots of pre-sliced models already on a drive and a cottage business to run, you dont want to waste your time going back to re-slice every single file with new settings. I just went back to my old standby resin. Its more expensive but without changing a single thing on my printer, the prints just started coming out beautifully again. I wish I could use Sunlu but until they address their quality issues (which, again, were GREAT when I started using them!) I just cant afford to waste time and money on failed prints.

This really is great resin. It prints great. The only downside is that the parts are noticeably more brittle than most other resins. I use this resin for larger prints that are thick enough that breaking it is not really a concern, like buildings or large miniatures. Thats where this resin shines, it makes larger prints way more affordable to print. I gave it 4 stars because its not perfect but its damn good especially considering the price.
