RICH-OPTO 3D Printer Resin 1kg LCD 3D Printing Liquid UV-Curing 405nm Rapid High Precision Quick Curing Standard Resin White

I admit it.. I'm a newbie. My experience in SLA printing is somewhat limited but I do have a fair amount of experience in FDM printing. I recently purchased a new Photon Mono printer and in my search for a cost effective resin, I stumbled upon this gem. Within a few days, I am printing complex, detailed parts with precision and absolute success. I couldn't be happier.The resin is almost transparent which I like. It's also pretty much odorless and easy to clean up with IPA. I'm printing at slightly cooler temperatures than recommended but I have compensated by increasing exposure just a bit. I printed the items in photo with 3 second exposure times and as you can see, they came out flawless. The detail is well beyond my expectations. The cured items are clean, sharp, and don't seem at all brittle. I'll definitely be buying more of this resin and can't wait to try the different colors.

The red is nothing like the picture, nor could it be called red. It is the color of pepto bismol only not quite as red.I would have been willing to give it three stars but is brittle as well. I'd post a picture for the color but I couldn't release any of my calibration prints except in fragments.Maybe other colors are better.EDIT: Added picture of calibration print made at 4s/layer. A proper exposure would be 8sec/layer or more; but you can see the "red" color and the fact that it is unusually brittle.UPDATE: Upped rating to 4 stars after I was contacted by Rich-Opto. They changed the description from "red" to "pink" and offered to compensate me for my dissatisfaction. 5 stars for customer service.FURTHER UPDATE: Customer support continues to be great. I found that (on my LD-002r) optimal layer time was 6 seconds or a little more. It really-really sticks to the build plate. I have reduced first layer to 4 layers at 30 seconds (down from 50 seconds) . I'm now very happy with this resin; upped to 5 stars.

For reference, I have a Anycubic Photon Mono X with a flexible build plate. I modified the default printer settings from 1.5 seconds per layer to 2 seconds per layer with a one second off time and 7 mm of lift. These settings have resulted in super clear and crisp models.I had some issues with the first bottle, contacted support, and they sorted everything out for me with super fast response time. I'm a bit of a night owl and expected to be playing email tag with them over several days, but, that was not the case. Even with the back and forth, all was sorted in an hour.As with most clear resins, after washing it does become a little bit cloudy. I figured out that spraying things off with an air hose after the print comes out (in an enclosed box), gets the extra resin off, without getting the IPA cloudyness. The model of the water and the marine were not washed, just cured. They came out really clear. Lots of details in the gears and machanics of the suit. I did wash the benchy and the tag in the Anycubic wash and cure, and the results are a brighter but more opaque blue. So if you want a brighter less clear blue, wash then cure. But if you want super clear prints, just spray the extra resin off with an air compressor or can of air. Just make sure to have the print in something enclosed so you are not spraying uncured resin everywhere.Overall this resin is fantastic. It holds its own against more expensive resins. I will admit, the price is what drew me in to make the purchase. I also purchased the Anycubic clear green. This resin works just as well at nearly $10 less a KG. I will continue to buy this brand. I am currently also testing their ABS-Like resin. So far this brand seems to be top notch. Love it!

First foray into resin printing on the mars 2 mono. Pretty much dived in head first, used 3 sec layer time, 45 sec initial layer time (5 layers). Odor was virtually non-existant, which made it pretty enjoyable to use.Color came out frosted, but thats to be expected and a quick shot of laquer made them completely clear.Once cured, thin parts are still a little flexible but dont feel as if theyre going to break unless excessive force is used. Thicker parts are very ridgid, but still sand reasonably even after 20 minutes of curing, so i wouldnt recommend this in any structural or bearing application.But to be honest, this would be for asthetics and hobestly, i think im going to keep buying this as my everyday resin. Very impressed and happy
