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.

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 it's closer to grey, but still whiter than most greys I've 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 aren't careful, you'll snap these off, which do so, so cleanly, you'll think they didn't 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 doesn't break the bank. They seem to have a bundle deal on their website that pushes the cost down further. If you order 5 bottles, it's $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 wanted to print something that would genuinely feel like silicone or soft rubber for some grips but Siraya's rebound is too viscous for my m7 max. I tried a variety but the Sunlu was amazing. Closest to the softness of the Rebound, half the cost and yet somehow significantly less viscous. It was hard to find reviews on it, let alone where people weren't just using it as an additive to reduce other resins brittleness but I can attest in both regards it worked very well. True to its 66a claims and even compatible on large format printers it was fine. The cleanup with IPA was like any other resin. The results were invulnerable and while it doesn't have the same rebounding, it was extremely durable and flexible. Significantly easy to use without any failure, even on my first print with 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
