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)

Very nice details and fast curing.

Holds detail well, and seems more solid than a lot of resins that we have tried - we will be buying it again. It was also the first resin we used, with a 1L bottle coming with our Sonic Mini 4K.

This is easily my favorite resin. Works great with stock settings in my slicer. Prints great detail !!! For minis ... this is my favorite resin !!! I actually mix this with Aqua Green and it’s a bit less brittle. I’ve been having great success with both the grey and the green !

For a novice printer like myself, this is the absolute best resin I could hope for. Absolutely no failures, printing everything I threw at it with high fidelity on the default chitubox settings in a Phrozen Sonic mini. Printed upwards of 30 miniatures, and some much larger pieces (like the tank and also a small cottage) before running out. Tried another cheaper brand after this and was floored by the lower quality, will be going back to Phrozen for faster print times and ease of use. 10/10 especially for first timers

Prints come out extremely well and outstanding detail. I am a beginner in resin printing, and this was very easy to use.

Excellent results. Once cured, holds paint great.

The resin works well in my Phrozen Transform Fasrt.

(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.

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

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.
