When the print is finished, do you have to be quick to clean the part from excessive resin? Or do you work in a dark room?

Can be washed in a room with normal light. Preferred to be warm light. Protect from cold or sun light.

I've searched the net for UV-LEDs and UV-hardening resin.
The prices for resin vary from 29€/liter to 79€/liter. I wonder what the difference is.

The LCD screen you are using is monochrome? Or can I use any LCD without backcover?
