MC3DPrint

Wind anything. Print anything.

MC3DPrint turns matter into Filament Units, and filament back into matter. Wind copper, print gold. Wind sculk, print diamonds. Scan a whole castle and print that too.

No creative mode. No commands. Everything is a machine you build, power, and feed.

The exchange rate

Filament Units are denominated by tier, not by item. Wind a material and you get filament at that material's tier. Spend it and you can print anything at that tier or below. Within a tier, matter is interchangeable.

This is not a duplication exploit, and the economy is built so it can never become one. Filament spends downward, never up, and winding is strictly exact-tier. Printing carries a markup, so a print costs a little more than the matter is worth. The ratios above are break-even, which takes four Efficiency modules and therefore a Tier 4 or higher machine.

Print structures, not just items

Point the Structure Scanner at anything you have built. Every block, every state, every connection gets captured to a Blueprint Disc. Drop the disc into a printer, give it power and filament, and the build reconstructs block by block exactly as scanned: stair shapes, fence connections, chest contents, the lot.

Blueprints come from three places:

• Scan your own builds with the Structure Scanner
• Find them as loot throughout the world
• 130+ curated builds ship with the mod: castles, farms, libraries, towers

You can also import WorldEdit .schem, Litematica .litematic, and vanilla or Create .nbt files straight onto discs.

Eight tiers of machine

Tiers 1 to 4 are single-block desktop printers. Tiers 5 to 8 are N×N multiblock fabricators that lay down entire bases in one job. Upgrade modules tune speed, efficiency and capacity, or wire a machine's busy signal into redstone. Every machine also reports job progress to a comparator.

What else is in the box

• Filament Winder, Rack and Cable for storing and moving FU
• Filament Item Sorter that routes items to the matching-tier winder
• Blueprint Repository to catalogue your discs and re-burn copies
• Resins: consumable modifiers that grow crops, fill chests, or speed a print
• Deconstruct Mode: run a print in reverse and take a build back as filament
• MC3DPrint Terminal: with Applied Energistics 2 installed, order prints from your ME network paid in Filament Units
• Filament Unit values for modded materials: AE2, Mekanism, Thermal, Tinkers' Construct, Create, Botania, EnderIO, Immersive Engineering, Draconic Evolution and Mystical Agriculture, all soft dependencies that are completely invisible when the mod is absent
• In-game guide via Patchouli, and full JEI integration showing whether any item prints, winds, or neither

Supported versions

Optional: Patchouli for the in-game guide, JEI for recipe and FU lookup.

Integrations

Every mod below is a soft dependency. If it's installed, MC3DPrint knows about it; if it isn't, nothing happens at all: no crash, no warnings, no stray config. MC3DPrint has no required dependencies.

• Applied Energistics 2 — 10 materials, plus the deepest integration in the mod: the MC3DPrint Terminal, an ME cable part that lists what your networked machines can make and orders it, paid in Filament Units. It dispatches a real job to a real machine and the finished items land in ME storage.
• Mystical Agriculture — 35 materials (the essence ladder, ores, gemstones), plus 4 more from Mystical Agradditions. The most conservative pricing in the mod, because essence crops turn mining into farming and that's the fastest way to break an economy.
• Mekanism — 23 materials (mined ores and alloys, up to the Tier 8 antimatter pellet).
• Immersive Engineering — 19 materials (mined metals plus Arc Furnace and Crusher output).
• Thermal Series — 19 materials (mined metals plus the Induction Smelter alloys: signalum, lumium, enderium).
• Tinkers' Construct — 16 materials (Smeltery alloys, plus cobalt because it's mined).
• Botania — 11 materials (mana infusion and ritual altar output, manasteel up to life essence).
• Ender IO — 9 materials (the Alloy Smelter ladder, redstone alloy up to end steel).
• Draconic Evolution — 6 materials, and the gate on the biggest machine in the mod: the 9x9 Tier 8 Fabricator needs Awakened Draconium corners, so without Draconic Evolution installed Tier 7 is the ceiling.
• Create — 6 materials (zinc, andesite alloy, brass, rose quartz).

Two optional tools on top of that:

• JEI — two extra recipe categories: what an item costs to print (price and tier), and what's inside a Blueprint Disc.
• Patchouli — the in-game Fabricator's Handbook, craftable from an Extrudium Crystal and a Book, or handed out with /mc3dprint guide.

Shared materials are priced to match across mods: steel costs the same in Tinkers', Mekanism and Immersive Engineering, so no pack can arbitrage one mod's steel into another's.
