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

Good price and predictable results.

I’m new to resin printing and I haven’t tried any other types of resins, but I’d say this is a good starting point

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!

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

Works and that’s all it matter when it comes to resin.

"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.

I keep this resin in stock always, use it to make very detailed anime figures. It's a nice color to be painted over. Allows for fantastic print quality and any texture. Very durable once printed!

It good
