MC3DPrint
Learn the mod, one system at a time.
From your first scan to printing an entire base with a multiblock fabricator. Prefer it in-game? MC3DPrint ships this same guide as an in-game Patchouli book (Patchouli optional).
Basics
Scan, disc, print — and the Filament Unit economy that powers it all.
Scanning a build
Capture any structure with the Structure Scanner and save it to a portable, printable Blueprint Disc.
Read → BasicsPower, filament & I/O
Wire up a printer's faces for discs, filament spools and RF, then arm it and start a print.
Read → BasicsBlueprint Discs & files
How written discs reference saved scans, read their tier and print cost, and import or export as files.
Read → BasicsFilament Units & the Winder
Turn raw materials into Filament Units on the Winder, then dock the spool to fuel a printer.
Read → BasicsThe FU economy
Why tier is value, how block costs are derived, and the down-only rule that governs every print.
Read → BasicsAlternate styles (texture packs)
Two optional built-in looks — Blueprint Mode and Dark Mode — ship inside the mod and flip on from the Resource Packs screen.
Read →Machines
Printer tiers, upgrade modules, the rack, the cable, and the repository.
Printer tiers (T1–T4)
Single-block printers from T1 to T4, each printing faster, cheaper, and bigger structures than the last.
Read → MachinesUpgrade modules
Four module types tune a printer's speed, FU cost, RF cost, and buffer, with a cap of four per type.
Read → MachinesThe Filament Rack
A bookshelf-style rack that stores eight Filament Spools and doubles as a backup FU reservoir for machines.
Read → MachinesMC3D Cable
A single wire that carries both Redstone Flux and Filament Units, connecting machines and racks losslessly.
Read → MachinesThe Blueprint Repository
A library block that catalogues your Blueprint Discs and re-burns fresh copies of any build on demand.
Read → MachinesDeconstruct Mode
Run any printer or fabricator in reverse — consume a region back into Filament Units at a lossy rate.
Read → MachinesThe Filament Tier Item Sorter
A passive, unpowered logistics block that routes each item to the Filament Winder holding a spool of that item's material tier.
Read →Multiblocks
Assemble and form the T5–T8 fabricators that print at scale.
Resins
One-shot additives that make a print come out finer — not just bigger.
Resins overview
One-shot additives that make a found-blueprint print come out finer — better, not just bigger.
Read → ResinsWhat resins do
The six resin effects — from fully grown plants to ore-salted stone — and how rarity scales them.
Read → ResinsFinding rare resins
Rare-tier resins can't be crafted — they drop only from end-game loot, and two effects exist only at Rare.
Read →FAQ
Why won't it print? How do I move the build? Auto vs manual? The quick answers.
