Extremely impressed! This stuff is some of the least expensive out there, and works great! Prints come out perfectly and clean. I even forgot I hadn’t cured some recent prints yet because they were so clean post washing and dry. Love this brand!

Great quality and a great price. Easy to use and clean. Great prints. Normally a print needs 8 sec on my 2K Photon, I got this down to 6.5 sec with this resin.

I use this for all my 3d printed statues and cosplay props. Its rigid but not brittle. So it works perfectly for statues. The price point for how this stuff prints is amazing. Im able to use the same printer profiles across all sunlu resins that ive tried, which is a huge time saver.

This is my go to resin. Works great in every printer I've owned (Saturn 2, Saturn 4 Ultra, M7 Max)

Color: 1kg Beige

I purchased the beige resin. I'm a little dissapointed that the default picture on the store is indeed beige, but the actual color of the resin is a peachy "skin tone". The resin itself is thin, which is nice so that it flows well in the vat. It does require a bit more exposure time that my sirayatech resin does (somewhere around 3.5 seconds on an anycubic M3 max). That said, I had no failures out of the bottle using the default Lychee slicer layouts and supports. Lychee is nice because you can enter your machine and resin and there's a good chance it can provide a profile that will get you started. As for the actual prints, they came out crisp and clean. Though I will say the surface texture is noticibly chalky compared to more premium resins. The resin is extremely brittle. Which is typical, but not at all abs-like. The instructions warn not to leave the resin out, and if it would sit more than a couple days, to return it to the bottle. I can confirm that it starts to separate out this quickly, and when it does so, it separates like spoiled milk, with the resin looking splotchy and curtled. Not a big deal, you just have to shake it back up and its good to go. But again, more premium resins can last for a week in my vat with minimal separation. And when they do separate, usually the color falls to the bottom evenly. Overall, I'll probably purchase more of Sunlu's resin in the future. This performance was acceptable for the parts I generally produce as they need to be painted anyway. And hey, it's half the price of higher quality variants. Just make sure you shake vigorously and return leftover resin to the bottle if you're not going to use it.

Okay, I'm not a 3D resin printer expert but I did get this to work after a bit of trial and error and would like to offer a few points for consideration: (a) This is a thick resin. When starting a print, the motor and gear couldn't push the resin fast enough. Therefore, it seems to like to be a bit on the warm side to make it a little runnier. If that does not help, what did work 100% of the time is to use the front panel and sink the build plate into the vat and then start the print. That way it didn't have to push around so much material and printing started perfectly every time. (b) Be careful of void that generate suction. I got into the habit of putting in supports even with not needed to eliminate the suction. (c) Solid forms are still hard and of course, use more resin. Hollowing out will give large forms the soft feel. How thick depends on what you are attempting to achieve, but I just offer this as a note so that you can start experimented from the start. I have not been successful in creating a gadget for an enclosure. I'm still trying to figure out out make those work well. Anyhow, do expect some serious trial-and-error but when you get dialed in, the results are pretty neat. BT recommended if you like to experiment

"In my workshop, I run various resin and laser printers. I have recently added the UniFormation GK3 Ultra to my setup. As resolution is key for my work. I needed a reliable 'workhorse' resin for a complex prototyping run and decided to put this 1kg bottle of SUNLU Standard Grey through its paces. The fluidity right out of the bottle is excellent; it flows into the vat smoothly without introducing the stubborn bubbles that can ruin high-detail prints. I was running a long, intricate design, and the dimensional accuracy was spot on—I saw no noticeable deformation or shrinkage compared to my digital models. While working at the bench for several hours, I also appreciated the minimal odor. It didn't overpower the space during the printing cycle. Post-processing was simple with a quick isopropyl alcohol bath, leaving a clean, smooth matte finish that is immediately ready for the next stage of work. For the price and the stability it provides, this resin is an incredibly cost-effective choice for anyone needing high-precision results.
