Building 75mm Gatling Rail I in EVE Online

What it takes to make 75mm Gatling Rail I, straight from the game's own blueprint data: every material and how many of each. The calculator above prices that list at one region's orders and draws the whole chain as a graph.

What goes into one run of 75mm Gatling Rail I

1 unit per run
Material	Per run	Can be built too
Tritanium	231	no - buy or mine it
Pyerite	220	no - buy or mine it

Production runs in whole batches. One run of 75mm Gatling Rail I gives 1 unit, so asking for fewer than that still means one full run - the game has no half runs, and rounding down would quietly tell you to buy the missing pieces.
