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)

This is easily my favorite resin. Works great with stock settings in my slicer. Prints great detail !!! For minis ... this is my favorite resin !!! I actually mix this with Aqua Green and it’s a bit less brittle. I’ve been having great success with both the grey and the green !

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 got this as my first-ever resin for my Epax E10 to make the most of the high-resolution screen. I printed a miniature with long thin weapons and many small details. Printing at 0.5mm layer height with 2s exposure worked great, and supports pulled off painlessly after washing but before curing for 2 minutes. I use 4 base layers at 15 seconds each. For more challenging prints Ive had to raise the exposure up to 2.5s to give the supports enough grip on the large pieces. The finer parts like spears have a surprising bit of stiff flex to keep them impact resistant (but not bend resistant). I have some flex resin on the way to try mixing this with just to experiment for more injection-molded-like durability, but this stuff is already better than I expected. I knocked a star off because the fumes really made my big open basement unbearable without a respirator. You always need one anyway, but I thought the claimed low odor would do well in such a huge space.

Works very well. All prints have been perfect so far. Definitely will get it again when I need more resin.

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.

Easy to dial in and the print quality is outstanding.

Very nice quality resin, especially for miniatures. Uncured resin cleans very easily with IPA compared to other resins Ive tried. This is my new go-to resin for miniatures!

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

It works well for me.

Works great with my Mini and Mighty 4K
