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’m new to resin printing, but in the past 2 weeks I’ve tried both the Anycubic Eco Resin and this Phrozen Aqua-Gray 4K. The Anycubic Eco has been much better both in terms of build quality and smell. This Phrozen resin is very smelly to me. I’m sure it’d be fine for those that have good ventilation, but it was terrible for me as I only have one small window to vent my space. I’m not sure how this qualifies as “low odor” but I’d very much recommend using only in very well ventilated area and possibly even a respirator. The build quality was fine, but I actually got better prints with the Anycubic Eco resin. The Phrozen came out brittle. This very well could be my print settings as I’m using Chitubox’s default profile for this resin with my Phrozen Sonic mini 4K and I had to create my own profile for the Anycubic Eco (0.05mm layers, 9 second exposure, 60 second base layer exposure, 8 base layers). Lastly, it’s much cheaper buying directly from Phrozen. Not sure why Amazon tacks on an extra $10/kg. Overall, it was definitely usable, but it seems like there are better products out there in the market.

(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.

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.

Best for sonik 4k mini

Perfect for our Phrozen 3D printer! No complaints here !

Works very well. All prints have been perfect so far. Definitely will get it again when I need more resin.

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.

Got it for my brother for the 3D Printer and he’s used a lot of ink so far, it’s a bit pricey per bottle.

Its resin. It works. Nothing unusual
