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.

Prints great and easy to work with!

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.

Works great with my Mini and Mighty 4K

I’m new to resin printing, but in the past 2 weeks I’ve tried both the Anycubic Eco Resin and this Phrozen Aqua-Gray 4K. The Anycubic Eco has been much better both in terms of build quality and smell. This Phrozen resin is very smelly to me. I’m sure it’d be fine for those that have good ventilation, but it was terrible for me as I only have one small window to vent my space. I’m not sure how this qualifies as “low odor” but I’d very much recommend using only in very well ventilated area and possibly even a respirator. The build quality was fine, but I actually got better prints with the Anycubic Eco resin. The Phrozen came out brittle. This very well could be my print settings as I’m using Chitubox’s default profile for this resin with my Phrozen Sonic mini 4K and I had to create my own profile for the Anycubic Eco (0.05mm layers, 9 second exposure, 60 second base layer exposure, 8 base layers). Lastly, it’s much cheaper buying directly from Phrozen. Not sure why Amazon tacks on an extra $10/kg. Overall, it was definitely usable, but it seems like there are better products out there in the market.

I just recently purchased a Phrozen Sonic Mini 4K and managed to grab some Aqua 4K Grey as well (it is hard to find in Canada so had to order it here). I havent used other brands of resin yet, but so far Aqua 4K resin works great! There doesnt seem to be much shrinkage; the resin smell is relatively mild (in my opinion); print quality is fantastic and works really well at 2.5s exp @ 50um and 1.9-2s exp @ 30um layer heights. I accidentally dropped part of a model, comprised of detailed fingers/nails, from about a foot onto my desk and nothing broke. You can snap thin parts if youre not careful but the prints seem durable enough for gaming and certainly strong enough for show-pieces. Overall Im quite happy with this resin!

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

It works well for me.
