phrozen Aqua-Gray 4K Resin for High-Precision 3D Printing,405nm LCD UV-Curing Photopolymer Resin for Low Shrinkage, Great Detail, Low Odor, Non-Brittle (1KG)

Excellent print quality. Follow the guidelines laid out by layer height, Phrozen lists them online for ease of use. Just wish I could buy this stuff in 5kg jugs or more. Gets expensive buying singles, amd even with Phrozens sales from their website, the shipping is insane. Amazon is the way to go for this stuff right now. Update: 5-5-21 On my fifth bottle(consecutive orders over last few days). Consistent results every time. Very good detail.

Holds the details for the smaller prints. Little shrinkage for the large multi-piece prints. I pay the extra couple of dollars for this resin over others Ive tried for its reliability, quality and ease of use. Would recommend. Just make sure to leave enough for me.

I have the Phrozen Sonic Mini 4K printer and I have used both rapid resin and standard resin and the print speed over longer prints is a pretty big difference. This has worked really well for small and large prints and the smell isnt too bad. I really like this resin from Phrozen and I will likely keep going with this brand to keep it consistent with my printer.

I have been trying to get good prints out of this resin since buying my Phrozen Sonic 4K, not the inexpensive 4K Mini, I have the dental lab version. I have had endless issues with prints falling off of the build plate, deforming, sagging, stretching, detaching, you name it. At first I thought it was just a bad batch of resin, so I bought more and tried again. Nope, this resin just plain sucks. Most of what I do is 1/87 scale models and miniatures, primarily vehicles and equipment. Its just terrible. Yes I am experienced in 3D printing for many many years, yes I tried changing my exposure times and lift speeds. Yes I tried the suggested settings from Phrozen. No I dont have ANY problems like this with other resins. I found that mixing this stuff 50/50 with Siraya TECH FAST ABS Gray works pretty well if you need to use up your 4K Resin and dont just want to dump it. The Siraya FAST ABS is all around much better stuff. Sorry Phrozen. You guys make fantastic printers, some of the best actually, but Im done buying your garbage resin.

I ordered 2 bottles of 4k grey resin to Chile. 1 month later, I got the 2 resins in the correct package, but to my surprise, when I opened them, they were 2 bottles of phrozen abs-like resin. I wont go thru the process of getting them back.. so i am stuck with these resins. I tested them. Worst resins I have test. Printed in phrozen mighty 4k, they where so stuck to the base plate, that when I was going to remove them they shattered in small pieces. bad resin. not what i ordered.

Best for sonik 4k mini

Works very well never a problem with Phrozen

Just what I needed. I started with MatterHackers build series resin.. huge mistake. Printer: Phrozen Sonic 4K

Perfect for our Phrozen 3D printer! No complaints here !

I can’t get the settings dialed in and far too many prints fail. Switching to Siraya Tech Fast Navy Gray.
