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 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.

I ordered 2 bottles of 4k grey resin to Chile. 1 month later, I got the 2 resins in the correct package, but to my surprise, when I opened them, they were 2 bottles of phrozen abs-like resin. I wont go thru the process of getting them back.. so i am stuck with these resins. I tested them. Worst resins I have test. Printed in phrozen mighty 4k, they where so stuck to the base plate, that when I was going to remove them they shattered in small pieces. bad resin. not what i ordered.

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

Very nice details and fast curing.

Just what I needed. I started with MatterHackers build series resin.. huge mistake. Printer: Phrozen Sonic 4K

Print quality is only a little better than abs like resin. And youll need to increase the cure time on the initial layers

The print quality is amazing. Dosnt Crack or break when printing. Easy to cure and the smell of the resin is not strong . And the color you pick is spot on to what is shown on the website .I give this resin a 5 star review.

Excellent results. Once cured, holds paint great.
