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)

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.

Es una resina muy buena, todas mis impresiones las hago con 30 micrones y el patron de impresión baja bastante frente a otras resinas. Recomiendo al 100% esta resina.

The resin is great to work with. Unlike the Phrozen Aqua 8k resin which is brittle after printed, there is a some a good amount of flex with the material and the supports just peel away and leave little damage to the part after just printed and washed. The resin consistency is really good too and I keep track with the resin with a resin calibration test (Cons of Calibration) with every print to keep track of the exposure and the exposure doesnt change on me. Ive tried several resins including a mix of Fast with Tenacious before to get flexible parts and even used onyx resin but this is better for miniatures and figures.

Great print quality. Works great with the manufacturer recommended settings. I want to check out the water washable stuff next. No complaints thus far. I use a Phrozen Sonic Mini 4k with this resin. I have used other resins with this printer to great success but something about this resin stands above the rest in regards to overall print quality. I just wish they made a 4k water washable with the same level of detail. Maybe one day!

Used in a sonic mighty 4K Chitubox included resin profile works without modification. Prints are clean. Vat life seems good, part isnt as horribly brittle as some other grey resins. Would buy again.

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.

Good quality

Phrozen does not make a green or clear 4k resin only grey and ivory very misleading for those that dont know! Please remove those colors from the page!

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.

Works great with my Mini and Mighty 4K
