Made to work at purple tech, this BP takes in entirely raw resources and outputs a fair amount of Mk3 spray in a compact form factor. Important Notes:
Due to lack of kimberlite, this BP takes in a large amount of coal for both Mk1 and Mk2 sprays.
Unlike my larger spray BP, this one does not require any kind of stacking.
This BP relies on fire ice (semi-common spawn in home systems) to provide graphene, without it you will need to belt in graphene from another production line instead.
As this BP self-sprays, it takes some time to properly spool up. If you have some existing spray already you can add it to the spray coater belts to speed up the process.
This BP comes in just barely under the limit of Mass Construction 4, making it one of my smallest prints.
