Filament inventory, honest costing, customer orders and live printer control. Ten screens, one app, not a single server.

Why this exists
Your slicer shows grams. Your bank shows the monthly total.
Nothing lives in between.
With one printer everything fits in your head. Add a few more and the first thing you lose is the money: how much filament is actually left, what a specific print really cost once electricity and wear are counted, whether you made anything on that order — or quietly paid for part of it yourself.
The usual fix is a spreadsheet, abandoned a month later because every print has to be entered by hand. SpoolFarm closes that gap on its own: it writes filament off when a print finishes, computes the real cost and shows the profit on every order.
The five screens everything else rests on.
Farm overview
Printers of different brands in a single list instead of four separate apps. You can see at a glance who is printing, who is idle and where something went wrong.
Inventory
The remaining weight drops by itself when a print completes. Nothing to enter by hand — that is exactly where spreadsheets usually die.
Money
A slicer only knows about plastic. Profit is eaten by the items it never sees: electricity, printer wear, your labour and the share of failed prints.
| Model | Your slicer knows | SpoolFarm shows | |||
|---|---|---|---|---|---|
| Material | Time | Cost | Price | Profit | |
| Retail Display Stand | PLA · 410 g | 11 h | €1.80 | €3.43 | €1.62 |
| Desk Organizer Tray | PLA · 182 g | 5 h | €0.30 | €0.56 | €0.27 |
| Drone Frame Arm | PLA · 96 g | 3 h | €0.11 | €0.21 | €0.10 |
These are the same three rows shown in the screenshot above. On the left is everything your slicer will tell you. The right-hand half only appears once electricity, printer depreciation, labour and the failure rate have been accounted for. The amounts are illustrative — they come from the demo farm, not from anyone's real production.
Orders
The summary on top covers every order: how much is in progress, how much it brought in and how much of that survives the cost of making it.
Printers
Layers, remaining time and finish time, temperatures, axis movement, lighting and part cooling — all from the phone.
The ones you need less often, but without which the picture does not add up.
Not “blue PLA”, but the full history of one spool.
Two sides of the same week: what was printed and what was earned.
Where the plastic goes and how much money is frozen in stock.
Boxes run out just as quietly as plastic does.
The printer reminds you itself — before it comes up in the middle of an order.
Off camera: notification settings, server mode with a web interface, the filament loading wizard and K-factor profiles. The complete list is below.
The individual tools exist, and many of them are free. The difference is that none of them answers “did I make money on this”, and none keeps printers of different brands in one place.
| What a farm needs | SpoolFarm | Bambu Handy | Mobileraker | Spoolman + OctoPrint |
|---|---|---|---|---|
| Printers of different brands in one list | Yes, 5 ecosystems | Bambu only | Klipper only | OctoPrint only |
| Filament inventory with weight and price | Yes | No | No | Yes (Spoolman) |
| Write-off when a print finishes | Yes, automatic | No | No | Partly, via plugin |
| Costing: electricity, wear, failures | Yes | No | No | No |
| Price calculator before printing | Yes | No | No | No |
| Orders, profit, PDF invoice | Yes | No | No | No |
| Packaging stock | Yes | No | No | No |
| Analytics about money | Yes | No | No | No |
| Works without cloud or account | Yes | Account required | Yes | Yes |
| Needs a separate server or computer | No, all on the phone | No | No | Yes, always on |
Comparison as of August 2026, and only for the jobs a made-to-order farm has to do. Each of these tools is strong in its own area: Mobileraker goes deeper into Klipper, Spoolman is a mature inventory server, and OctoPrint has a plugin ecosystem a mobile app cannot match.
There is no SpoolFarm server. The app contains no analytics, no crash reporting, no advertising SDKs and no user accounts. The developer is technically unable to receive your data.
Spools, orders, customer names and prices stay on the device. Data leaves the phone only through integrations you configure yourself, and goes only to the address you entered: your printer, your server, your bot. The app also works offline.
SpoolFarm is out on Google Play, and testing keeps running alongside it: a limited group gets the builds early and sends back what they find before everyone else sees it. Some of the app's features came from other people's workflows.
