LONGER 3D Printer Resin, 405nm Standard Rapid Photopolymer Resin for DLP/LCD 3D Printing, High Precision & Quick Curing & Excellent Fluidity & Easy to Clean (Transparent Red, 1000ml)

Product arrived with resin leaking all over inside the packaging because the cap wasn't screwed on properly before shipping.... You really gotta be careful about touching UV resin since its carcinogenic.Update*Seller reached out to me and sent me 2 replacement bottles, one of them was fine, but the second one was also uncapped slightly which leaked all over in the bag. It could be that the amazon warehouse is storing them improperly and that there could be pressure built up in the warm summer, but i'm glad the seller tried to make up for it.

The media could not be loaded.  I purchased a Longer 10 about six months ago for the purpose of printing gaming minis. I have loved everything about it. I had an opportunity to get a deal on some non-Longer brand resin so I thought I would give it a try. What could go wrong. The first print seemed to be ok but the follow prints did not go so well. I messed with setting on the software and the models to no avail. I reached out to Longer technical support. Although this review is not about their support, it is five stars also. They have since emailed me multiple times to follow up to make sure the issue is resolved. After a few attempt to resolve the issue I was having, the tech asked what kind of resin I was using. They suggested I try to eliminate one of the variables by switching back to Longer resin. From the first print and to every print here after using the Longer resin, each was crisp and clean. I wish my photos could better convince you.

I really like this resin. The only reason it isn't 5 stars is because the bottle arrived saying it was 500g by weight when the item says it's suppose to be 500 ml by volume. Unfortunately 500g by weight is less than 500ml

The resin worked fine, after all the comments about smell from resin printers I was surprised to find it not that offensive. I had previous experience with non printing casting resin and that is very obnoxious. The printed object came out pretty hard with good detail before UV curing so I am very pleased with the results. Cleaned up well and easily filtered back into the bottle.

After printing for a bit with regular red resin I decided maybe trying out the water washable resin might be a good idea, it would cut down costs on IPA and washing my hands frantically in water after a spillage is much easier for my monkey brain than IPA. I'd heard all the horror stories and was prepared for less than ideal prints and was surprised to find a highly detailed print on the bed the next morning. Cleaning was a breeze and I left a happy camper. Pictured above is my first attempt at a print with this resin, a few of the errors are my shaky hands and my clips battling with the supports. I liked the resin and will definitely be buying a few more bottles. Just remember that this stuff is still toxic and should be treated the same way you treat normal resin. Anything you wash off the print needs to be cured and disposed of responsibly :).

Very new to 3D printing. Started with my ender and added an Elegoo Mars 2 to my household. Purchased the water washable due to I wasn't sure about buying alcohol so I wanted to find other alternatives but wanted something to play and test the new 3D printer out.This stuff works. Very easy to work with and has a slight smell, but that's a given with any resin. Easy to clean up as well. I purchased the wash and cure station and water seems to be the way to go with how much I clean it out!Have some white spots if not cleaned all the way. But I paint everything so it's doesn't matter.I wash for 5-7 min and cure for 2. Not sure if that's right but seems to work for me without everything breaking 🙃

works well in both machines stuck to build plate well and cleaned with IPA as well as several de greasers like simple green and mr clean

Not a fan of this. It works but it just doesn't cure like the other resins I have used. I've tried tweaking the profiles and everything. I get warping in the edges of the prints where with the same supports in a different resin I don't.
