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)

Good quality

Prints turned out really nicely. Used a Mini 4k Phrozen Printer.

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.

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 really like this product Amazon was really good for replacing the one that was damaged by the delivery driver putting the box by the rear tire of a car that ran over it but beyond that once I actually got the product and started using it it’s great does exactly what it’s supposed to and the prints are beautiful

I used to avoid Phrozen resins completely (I got a few with the printers and then a few more when they ran a sale on Amazon, and they all came in leaky bottles and they required massive supports). I avoided them for several years. Then I got Mini 8K with a bottle of their 8K resin, and the new bottle doesnt leak (and the seal is excellent) and it was very easy to print. So I tried the 4K resin. Its very similar to the 8K resin, slightly slower, marginally lower resolution that you can only notice with a small 8K printer. It has excellent printability and is easy to clean. After the IPA bath, its not tacky at all. I wave a UV light over it to cure any remaining wet spots and its done. I dont do the regular all-around curing on it, and it stays slightly flexible! Its actually hard to break, it will bend to the point that it doesnt recover the original shape, but it still wont break (you need to varnish or prime it, or it will keep curing and getting harder and more brittle). Even better, I found that it does not need to be primed: acrylic paints stick to it just fine, including contrasts and washes. The ivory resin has a pleasant color to serve as a base, and the grey resin can be used as-is in the shadows if you do zenithal priming with white.

This product is night and day better than the non 4k product. There were details in my prints that I didn’t even know were there until I used this product. I had printed the same thing using two different types of resin and the 4k was obviously superior. Make sure to shake well before use, still kind of a noob but I think it needs shaken well or it will leave a sticky residue. Picture quality isn’t great, it looks 10x better in person.

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

Prints great and easy to work with!
