Review on Washable Printing Photopolymer Non Clear Additive Manufacturing Products: Empowering Effective 3D Printing Supplies with Rich OPTO Technology by Rich Rickenbaugh

I have now used Rich-Opto Translucent Orange, Black and White. This white is simply unprintable. I was very fortunate to be able to use basically the same orange and black print settings. They have a lot of great prints, but the White-II is terrible. Most prints don't adhere to the build plate, but I've also had many issues with prints where some of the prints fail, why printing with supports doesn't print fully, or the print pulls itself without the build plate (again or poor adhesion). You would think that I could increase the exposure time on the bottom layers to overcome this, but I went as far as trying to double the exposure on the bottom layers by slowing down the prints to half the speed by I increased the number of bottom layers. etc. Nothing helps. It's just waste resin. I'll try to mix it in very small amounts with some of my other resins that I'm good at printing so hopefully I can use this junk without spoiling the prints. Just take a look. Maybe I just need to open the whole bottle and throw out this whole mess. Very disappointing.
