Simple and efficient Mk3 spray maker. Each unit makes 2.5k/min after self-proliferating, and imports only coal, kimberlite, and nanotubes!
Important notes:
This BP relies heavily on the integrated ILS piling from "Logistics Station Integrated Logistics"; without this upgrade it will only work at a fraction of its usual effectiveness. Unpiled outputs (no upgrade) will work at ~25% capacity, increasing to 50%, 75%, and eventually 100% as the upgrade is leveled.
Nanotubes are imported directly, rather than spiniform/stag crystals, as it's three times as efficient on logistics. All my blueprints function in this manner.
The entire print consumes one quad belt of coal, and a single blue belt of kimberlite and nanotubes.
This BP is very thin laterally, so you can fit five into a single section of the equator band, as well as being able to fit into the first tropic.
This BP is not self-powered. It consumes around 320MW of power to run with default tower settings, but you'll want to run it with max charge, so expect each print to consume closer to 620MW.
