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 got this as my first-ever resin for my Epax E10 to make the most of the high-resolution screen. I printed a miniature with long thin weapons and many small details. Printing at 0.5mm layer height with 2s exposure worked great, and supports pulled off painlessly after washing but before curing for 2 minutes. I use 4 base layers at 15 seconds each. For more challenging prints Ive had to raise the exposure up to 2.5s to give the supports enough grip on the large pieces. The finer parts like spears have a surprising bit of stiff flex to keep them impact resistant (but not bend resistant). I have some flex resin on the way to try mixing this with just to experiment for more injection-molded-like durability, but this stuff is already better than I expected. I knocked a star off because the fumes really made my big open basement unbearable without a respirator. You always need one anyway, but I thought the claimed low odor would do well in such a huge space.

This is a great resin for miniature printing. Dial in your exposure settings and this resin will yield great results.

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!

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

(UPDATE 10/14/20) so now with stocks lasting Ive been able to pickup 6 more bottles for a nice stock of resin. Already gone through 1 1/2 bottles in the last week sense October 5th. I have notice with this new stock the sediment issue I said bellow is not affecting me so quickly as the first sept batch did. This batch is doing much better. Still separates quickly and needs mixing every other print. But at least now I know what to expect with batches that are not very good. So been using this resin now for a week. I was only able to nab a single bottle before selling out and hopefully get more with restocking. The review. So far my week of use and constant printing Im loving this resin! The detail and fast curing with a monochrome setup is great! Im using a mars 2 Pro at 2sec times. The details are fantastic and on par with some higher end resins that would normally cost around $70-$80 for a bottle. This new 4k resin knocks it out of the park... But it isnt without fault as well. I didnt notice until I was passing my 5-6 days of printing, that the resin does have 2 issues. 1st: it separates very quickly, so this does need regular mixing. Most resins I use I can sit for 3+ days before noticing separation. This resin does it within 24hrs of sitting. So mix often! 2nd: I noticed a problem with sediment build up. My preference in resin is elegoo abs and FTD Industrial Blend and both those resins I never had to consider sediment build up. But with this new 4k resin I started noticing support failure after day 4, day 5 print fails. I cleaned my vat and clogged the strainer because the build up was that bad after almost a week. That sediment also was sticking to the models to, so I had to use my brush to clean it up. Best way to put it is this resin prints fantastically well for how cheap it is IF! you have a monochrome screen to print with. But comes with the maintenence of a resin from 2018.

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.

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

Works great with my Mini and Mighty 4K

Very nice details and fast curing.

Very nice quality resin, especially for miniatures. Uncured resin cleans very easily with IPA compared to other resins Ive tried. This is my new go-to resin for miniatures!
