Hi! I'm the developer of this mod. Mostly made this for use with my friends when we found out that the duplication glitch using the Item Frame was patched out in Terraria 1.4. Now we just use this mod when we quick 1-day play-throughs to skip the grind.

In case the description gets updated without the recipe, here it is (use in a work bench):
20 Item frames
1 Iron Bar
1 Chest
1 Work bench

Additionally, made it so that newly made characters can get this from the start.

what is the recipe for the duplication station

No grind, pure calamity

PxinfulTrxsh hs the point you dont even know how tocraft that duper

How do you even make it though?

the entire point is to make the game easier, stop crying about a mod

This makes the game really boring does it not, just play journey mode at this point.

Epic mod
