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)

Delivery was much faster than expected. Good quality printing resin. Will buy again.

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.

Very nice details and fast curing.

4k sonic mini. I feel like I didnt see a difference in the details

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!

Print quality is soo crisp. Details are impressive. Nothing can beat that!!! So happy with this product. I ordered 60plus bottles of these for the past 6 months, and I am ordering for more. 5 stars for this product. Clap, clap, clap.

Not much to say here. Its a little bit expensive, but there isnt better resin out there for the Phrozen Sonic Mini 4k.

Item is being sold as a non-toxic solution. Bottle says it is definitely toxic and carcinogenic.

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.

Grey prints real nice. Item arrive as dated. All good packaging. will buy again when in need.
