I bought the dye experimentally, to give color to resin for SLA printing. Maybe it's not suitable for such use after all. It gave a nice and intense color to white resin with a minimal amount. However, there was material left at the bottom of the printing container, resulting in insufficient light transmission. It will be very good for the intended use, but it didn't work for the use I tried.

The 5 stars are always an exaggeration, but I will briefly mention why I gave such a good review:

For amateur use at least (since I cannot judge as a professional), it is exactly what it says. It doesn't require much searching to tell the truth because it is simply a color that will go into the resin, nothing special. Also, a very nice detail is that it comes in a syringe and you can directly add the quantities you want, especially if you have to deal with a very small amount.
