Note that this may work with the other items in the recipe.
Steps to reproduce:
Add NBT data to some iron, e.g by renaming it.
Attempt to craft a 3D Printer
Expected Behaviour:
The 3D printer crafting recipe accepts any items matching the item type, but ignores any data associated with the item.
Then you are able to craft the item.
