How to import a Factorio blueprint string

A blueprint string is a long line of text that starts with 0. It holds the whole blueprint, so copying the text is all you need.

Steps

1. On a blueprint page, press Copy blueprint string.
2. In Factorio, open the blueprint library with B.
3. Click the Import string button at the top of the library.
4. Paste with Ctrl+V and confirm. The blueprint appears in your library and can be placed like any other.

Blueprint books

A book string imports the whole book at once. Open the book in your library to pick the blueprint you want to place.

Space Age, quality and mods

Blueprints that use Space Age machines, recipes or quality only work with the Space Age expansion. Every blueprint page on this site says whether it needs Space Age and why. If a page lists unrecognised entities, the blueprint was made with mods, and those buildings are left out when you place it without the same mods.

Nothing happens when I paste

Make sure you copied the whole string: it is often thousands of characters long and has no spaces or line breaks. A string copied from a forum post sometimes loses its last characters.
