Blueprint Discs & files

The whole loop is simple: scan a build, save it to a disc, then print it anywhere a printer can reach. Scans are stored as blueprints in the world save; a Blueprint Disc is just the key that references one.

Working with discs

• Shift+Right Click a written disc to lock it against being overwritten.
• Discs also turn up in village and exploration loot — print what you find, no scanning required.
• To rename a disc, drop it in an Anvil and type a name (costs 1 level of XP).

Tier and print cost

Every written disc shows its tier — the highest material tier among its blocks. One diamond block in a pile of stone still reads as that tier, and that’s the lowest machine tier that can print all of it.

Each disc also shows a Print Cost in that top tier. Free structural blocks like water and crops cost nothing toward it. See the FU economy for how costs are derived.

Cross-mod builds

Some curated builds are made from another mod’s blocks and only appear when that mod is installed. The Coppertide Park set (a geyser lagoon, drop tower, lazy river, enclosed glass serpentine, pendulum half-pipe, and four-lane racer) is built from MC Waterslides blocks: install that mod and the six park discs join the creative list and world loot; without it they stay hidden. Their print costs derive from the mod’s own recipes automatically.

Import & export (operators)

• /mc3dprint import <file> reads .schem, .litematic, and .nbt files from world/mc3dprint/import/.
• /mc3dprint export writes the disc in your hand out to a .schem.

Shipped blueprints live in world/mc3dprint/blueprints/.
