Satisfactory Blueprints: Designer Mk.1, Mk.2 and Mk.3
Blueprints turn a single hand-built factory module into a reusable stamp. This guide covers the FICSIT Blueprints unlock at Tier 4, footprint differences between the three Designer marks, dedicated-server sync rules, mod-blueprint compatibility and the verbatim error strings you will see if something goes wrong. All numbers in this article reflect the live 1.1 build on the stable Steam branch.
2026 update callout: Satisfactory 1.1 changed how blueprints anchor
Patch v1.1.1.0 (build 416835, rolled out across the spring 2026 stable wave) reworked the Blueprint Designer interior grid. Designs saved in 1.0 still load, but the anchor offset shifted by one foundation; rotation pivot now sits at the centre of the designer floor rather than the south-west corner. If a pre-1.1 blueprint places one tile north of where you expect, that is the new pivot, not a regression. The 1.1 patch also fixed the Mk.3 designer save corruption bug that prevented blueprints over 180 entities from reopening.
Unlocking the Blueprint Designer
Three Marks, Three Tiers
Coffee Stain ships three Designer tiers. Each one is its own milestone and unlock; you do not upgrade a Mk.1 in place.
| Designer | Tier | Footprint (X x Y x Z) | Build cost | Best for |
|---|---|---|---|---|
| Mk.1 | Tier 4 (FICSIT Blueprints) | 32m x 32m x 32m | 10 Modular Frames, 20 Steel Beams, 50 Concrete | Small smelter banks, single-recipe modules |
| Mk.2 | Tier 7 | 48m x 48m x 42m | 10 Heavy Modular Frames, 20 Computers, 100 Rubber, 100 Concrete | Mid-tier assemblers, manifold sections, train stations |
| Mk.3 | Tier 8 | 56m x 56m x 50m | 10 Neural-Quantum Processors, 20 Fused Modular Frames, 50 Time Crystals, 100 Ficsite Trigons | Late-game manufacturers, particle accelerators, vertical refinery stacks |
The Mk.3 footprint is exactly 7 foundations wide at the default 8m foundation size, and 6 foundations tall. If you build past the floor or ceiling marker the Designer rejects the save with a red X icon.
Inside the Designer
Interior Grid and Placement Rules
- Snap origin: Centre of the floor since 1.1. Earlier saves used the south-west corner.
- Soft ceiling: The designer warns at 150 entities and refuses to save past ~200.
- Curved conveyors: Each spline point consumes more budget than straight belts. Replace decorative S-curves with right angles before approaching the cap.
- External inputs/outputs: Belts and pipes that touch the boundary wall become I/O nodes on the finished blueprint. Position them on the same wall to chain modules end-to-end.
- Recipe selection: Saved with the building. A Constructor set to "Iron Plate" will still be making Iron Plate when stamped.
What gets saved versus what gets dropped
- Saved: Foundations, walls, machines + recipes, conveyors (all marks), pipes, power poles + wires, lights, signs (text + icon), Smart/Programmable Splitter filters, overclock percentages, train track + signal placement.
- Dropped: Stored items in containers, raw materials inside machines, vehicle paths, train consists, power switch on/off state, tractor station fuel.
- Reset on placement: Production counters, uptime stats, all logistics float buffers.
Common errors and how to fix them
If you are searching for the exact text the game showed you, this is the verbatim list:
This blueprint was made in a Blueprint Designer of a different size
and cannot be loaded.You saved this in Mk.2 or Mk.3 and tried to open it in a smaller designer. Build the larger designer or rebuild the module trimmed to fit.
Failed to save blueprint: entity count exceeds maximum.Hit the ~200-entity ceiling. Break into two modules, share an external belt boundary, replace curves with straights.
Cannot place: collision with existing buildings or terrain.Even an invisible Slug node or a 1-pixel grass tuft counts. Lay foundations across the entire deployment area first, then place the blueprint on the flat surface.
Blueprint contains modded buildings that are not installed.
Entities will be skipped.The blueprint was saved on a modded client. Reinstall the same mod version on every client and on the dedicated server, then reload. Common offenders: Mini Storage Boxes, Refined Power, FicsItNetworks, Linear Motion.
Snap failed: anchor outside designer bounds.Pre-1.1 blueprint loaded into 1.1 with the new centred pivot. Place once, dismantle, save again to refresh the anchor.
Designing for re-use
Manifold versus load-balanced inside a blueprint
Manifold layouts (one trunk belt, machines tap off in series) tile cleanly because you only need one external input. Load-balanced layouts (perfectly split belts feeding each machine) waste designer space on splitter trees and hit the entity cap fast. For blueprints meant to be stamped 10+ times, manifold is almost always the right call.
Standard I/O wall
Keep all belt and pipe inputs on the north wall, all outputs on the south wall, power input on the east, hypertube/jetpack travel lane on the west. Stamps line up without rotation and the chain reads left-to-right when you eventually walk the factory.
Vertical stacking
The Mk.3 ceiling is 50m, about 6 default foundations. A four-storey refinery stack with internal jetpack pillar fits with room for an overhead Mk.5 belt. Pre-place ramp foundations on the ground level so the next stamp's bottom level lands flush with the previous stamp's roof.
Mod compatibility matrix
| Mod | Adds buildings to blueprints? | Cross-client safe? | Notes |
|---|---|---|---|
| Mini Storage Boxes | Yes | Yes if installed on every client | Common cause of "skipped entities" on vanilla joiners. |
| Refined Power | Yes (turbines, capacitors) | Yes | Power network state still resets on stamp. |
| FicsItNetworks | Yes (computers, network cards) | Yes | Wiring saved; Lua programs are NOT saved. |
| Smart Foundations | Pass-through | Yes | Counts as vanilla foundation in the entity budget. |
| Early Blueprint Designer | Saved as vanilla Designer | Yes | Replaces unlock cost only; produced blueprints work without the mod. |
| Linear Motion | Yes (rotators, sliders) | Server must also have it | Animated state resets on stamp. |
Sharing blueprints
File locations
Windows: %LocalAppData%\FactoryGame\Saved\SaveGames\blueprints\<save_name>\
Linux (Proton): ~/.steam/steam/steamapps/compatdata/526870/pfx/drive_c/users/steamuser/AppData/Local/FactoryGame/Saved/SaveGames/blueprints/
Linux native build: ~/.config/Epic/FactoryGame/Saved/SaveGames/blueprints/
Each blueprint is a pair: name.sbp (geometry) and name.sbpcfg (icon + description). Copy both or the icon will render with empty geometry.
Importing community blueprints
Drop the .sbp/.sbpcfg pair into the target save's folder, restart the game (the in-game refresh button is unreliable), open any Blueprint Designer matching the source mark. Cross-save imports only work if the source blueprint fits the destination's designer footprint.
Dedicated server considerations
Blueprints live on the client, not the server
The dedicated server stores the placed factory; each player keeps their own blueprint library locally. This means two players can hold different versions of the same-named blueprint, which is fine until both try to stamp at the same coordinate. Coordinate naming via Discord or in-game signs.
Performance impact of mass stamping
Each stamp queues entity spawns on the next tick. Placing 30 Mk.3 blueprints in quick succession on a busy server can spike tick time past the soft real-time threshold and cause a brief desync warning. Pace stamps a few seconds apart, or stamp during a low-population window.
Patch and version notes

- 1.1.0 (October 2025): Mk.2 and Mk.3 added; Mk.1 reduced from 36m to 32m to make the Mk.2 jump meaningful.
- 1.0 launch (September 2024): Original Mk.1-only Blueprint Designer at Tier 4.
Frequently Asked Questions
Can I edit blueprints after saving them?
Yes. Load the saved blueprint into a designer of the same mark or larger, modify, and save over the original name.
Do blueprints save the actual buildings or just the layout?
Both. Building positions, recipes, overclock %, splitter filters, sign text, and wire topology all persist. In-machine inventory and stored items do not.
Can I use blueprints from other players?
Yes. Copy the .sbp + .sbpcfg pair into your blueprints folder. The other player must not have used mods you do not have, or those entities will silently skip on load.
What's the maximum size of a blueprint?
Footprint cap is Mk.3 (56m x 56m x 50m). Entity cap is roughly 200, with curved belts and splines counted heavier than straight runs.
Do blueprints include the materials needed to build?
No. You provide all materials at stamp time. The blueprint shows a material requirement summary before placement.
Can I create blueprints of existing buildings?
No. Only the Blueprint Designer's internal grid records entities. There is no "copy from world" tool in 1.1.
How do I rotate blueprints when placing them?
Mouse wheel rotates in 90-degree steps. Holding R + mouse wheel since 1.1 rotates in 15-degree steps for off-grid placement against terrain.
Why does my Mk.3 blueprint fail to load after the 2026 patch?
Pre-1.1 Mk.3 saves used a corner pivot; the 1.1 update re-anchored to centre. Open, dismantle the contents, and resave. Coffee Stain published a one-time migration but it only fires the first time the save touches 1.1.
Can I delete buildings inside a placed blueprint without breaking the rest?
Yes. After placement the blueprint becomes vanilla buildings. Dismantle, modify, rebuild as needed. There is no "linked instance" relationship between the source and the placed copy.
