Review on 🚀 Revolutionize Your Manufacturing Process with RICH OPTO Non Brittle Elasticity Photopolymer Resolution Additive Manufacturing Products by Warren Hess

I ordered the black version and was a bit disappointed that it was partially transparent (this also seems to match the Rich-Opto Standard Black reviews). It still reads black, but subtle details are easily visible. (My reference to "real" black resin is Elegoo Standard Black). At the same time, the detailing is still quite good - on par with, and maybe even slightly better than, that of the Elegoo Black Resins. So why three stars? This is partly due to misleading color coding, but more importantly fine detail does not print well with this resin. I suspect it has to do with the transparency, but I've found that fine details print thinner than expected with this resin, resulting in them printing faintly or not at all. For my use case I wanted to increase the stability of thin parts that break easily with standard resins and this disadvantage outweighs this. However, I will note that the thicker parts will take more twisting/flexing than the Elegoo Standard Black, so there is some potential here. I might try gray resin as I assume it's not transparent and might work a little better. (I used Rich-Opto Gray Water-washable, and while I didn't prefer it to Elegoo resin, it was fine and definitely not see-through.)
