Assembly Blueprint is the Ala Industrial item that turns a crafting-table recipe into a physical object. It exists in two states: a blank that stacks up to 16, and a written blueprint that never stacks, because two identical-looking sheets holding different recipes are a reliable source of mistakes. Writing happens inside the Assembler itself — lay the ingredients out in the 3×3 ghost grid on the Record tab and press Write; the mod has no separate encoding machine. A written Assembly Blueprint shows its product right in the inventory icon, and the tooltip names the result and its count.

One craft of the blank costs 8 paper and 1 lapis dust and yields 4 blueprints, so every automated recipe spends a few resources — the natural economic brake on automating everything at once. Assembly Blueprint stores the ingredient layout rather than a recipe id, so the Assembler re-solves it through ordinary crafting recipes on every operation: changed recipes keep working, removed recipes stop cleanly. The item itself holds no energy; the Assembler does the work at 12 EU/t, spending 480 EU per 2-second operation and drawing materials from a connected Storage Module. Paper grows from sugarcane and lapis lazuli is renewable through wandering-trader trades, so the blank is fully renewable. The item works on Minecraft 26.2 (Java Edition) on both Fabric and NeoForge and burns in lava like paper.
