4 combinators set catalyst ratio → filter inserters → dedicated smelting
A compact blueprint designed specifically for plastic production, managing the early-game hurdles of Natural Gas and Multi-Phase oil. BA Early Game Mall:
Never place a blueprint without first using Helmod (mod) to calculate ratios. In BA, one Chemical Plant producing Chlorine supplies exactly 2.4 plants producing Plastic. A blueprint that doesn't reflect 0.4 of a plant will stall. factorio bobs angels blueprints
I cannot paste raw blueprint strings here (character limit), but search this exact string on Factorio Prints:
This is often the steepest learning curve. Blueprints for this stage typically include "voiding" mechanisms (flare stacks and clarifiers) to handle byproduct overflow that would otherwise stall production. Circuit Tiers: 4 combinators set catalyst ratio → filter inserters
The most successful BA base is a design. Each block processes one intermediate product (e.g., "Copper Ore Sorting" or "Electronic Circuit Boards") and outputs only to trains or a bot network.
Design tileable rows:
Skip vanilla furnaces in mid-game BA. Use:
: To make your blueprints easier to read, use mods like ShinyBobGFX and ShinyIcons to differentiate building tiers at a glance. Pro-Tip: "Temporary" is Permanent A blueprint that doesn't reflect 0
