Vat Coatings Thread

Vat coatings are the opposite of hairspray/gluestick/ABS Glue of FFF printing.

The idea is to ensure your prints do not stick to your vat, and instead stick to the build surface.

I'm going to start this thread off by mentioning LiquiGlide (http://liquiglide.com/). Heinz has started using this coating on their more recent bottles. I'm not sure if this is applicable to DropLit, liquiglide is usually used by/for industries, but it is a great new coating.

Generic Cell Guard (Amazon) is a lot cheaper than full price product that John is currently using (I believe). I don't know how well it works yet.

Another idea is to use Gorilla Glass. Some people have been using it as the build surface for their filament-based printers. It's a pretty good non-stick surface. Maybe a round of it can be placed at the bottom of the vat. It is VERY expensive though, but might be reusable for the price: http://www.mcmaster.com/#gorilla-glass/=t173su

FEP/Teflon Coating
"This material is a high-performance special order tape with a Teflon surface layer. It can be cut with scissors or a paper cutter to the desired size if you have a printer with different reservoir dimensions."

NeverWet is a 2 part spray that will work like LiquiGlide (i think) but can be bought at Home Depot for about $20.

neverwet also dries with a milky haze, wouldnt be clear so it would most likely either scatter light or block some, making it not work good for clean light transmission through glass.

NeverWet is also...less long term than one would hope, among some other minor issues Exciting product, underwhelming reality.

I found the teflon sheets extremely hard to separate from the backing. Enough so that they stretch and get wrinkles. It's a big effort. They do work, though.
