Hello,
it is an interesting idea.
This is not possible in this version as if you specify empty ingredients in recipe it crashes.
But we might fix it for 0.5.0.

Actually I noticed that drs9999 did this quite a while ago
simply use

Code: Select all

ingredients = {},

in an assembling machine recipe. True Factorio crashes if you leave it as a player-craftable recipe (probably do to factorio trying to detect the raw resources or just an inability to display nil as the ingredients) but you asked about a building anyways so

If you are not sure how to make it an assembling machine recipe it's something like this

Code: Select all

    {
      type = "recipe-category",
      name = "your-crafting-category" --whatever name you want to give your crafting category
    },
    {
        type = "recipe",
        name = "material", --recipe name, typically the same name of material the building will be producing
        category = "your-crafting-category", --the name you gave the crafting category above
        energy_required = 10,
        ingredients = {},
        result = "material", --name of the material produced
        result_count = 10 --number of 'material' that will be produced in one 'turn'
    },

Then just create an assembling machine entity and add your-crafting-category to the crafting_categories list (I didn't want to spam the post with the code for an assembling machine), don't forget to add a recipe for the assembling machine though.
