It requires to be placed in a structure in order to work. There are 3 different configurations, Fire, Water and Sand, each requiring a different structure and used to craft different items. Fire is solely used to craft Iron Scales, Sand is solely used to craft Iron Sand and Water is used to craft all other items the Netted Screen can craft.
Input items need to be dropped on the Netted Screen, and the outputs will be ejected from the top in the world. In the Water configuration, some outputs will instead be ejected from the bottom into the Water below. In the Sand configuration, Sand will accumulate into the Bamboo Slat Block below it, which can be removed by right clicking the Netted Screen with a Stick, which will be used once enough Iron Ingots are thrown on it.
