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)

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.

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.

For a novice printer like myself, this is the absolute best resin I could hope for. Absolutely no failures, printing everything I threw at it with high fidelity on the default chitubox settings in a Phrozen Sonic mini. Printed upwards of 30 miniatures, and some much larger pieces (like the tank and also a small cottage) before running out. Tried another cheaper brand after this and was floored by the lower quality, will be going back to Phrozen for faster print times and ease of use. 10/10 especially for first timers

Works great with my Mini and Mighty 4K

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

I’ve really struggled to get this resin to print well with my Sonic Mini 4K. Lots of failed prints where other resins work well.

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.

This is a great resin. Flexible enough to bend slightly without breaking before being cured. Really helps when printing and clipping supports off models. Low odor. Purchased many times.

Holds detail well, and seems more solid than a lot of resins that we have tried - we will be buying it again. It was also the first resin we used, with a 1L bottle coming with our Sonic Mini 4K.

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.
