There is already a way to recoat the resin trays so you don't have to throw them away. I've been doing this since I first bought my Form 1. It's pretty simple and the price isn't bad at all. Use Sylgard 184 you can buy it off Amazon. It comes with enough silicone to recoat your tray several times the cost is only $53. Here is a blog from way back in 2013. http://blog.madesolid.com/2013/09/ch...1-printer-vat/
