SpoolBoard is the 3D printer app that plans your queue, costs every print and tracks filament by the gram. It works alongside your slicer and any printer, so you always know what you have, what it costs and what to make next.
One calm app for the planning, filament and costing that slicers and printer dashboards leave out. Here is what you get.
Reusable spools, auto-numbered with printable QR labels. Stock is an append-only grams ledger, so remaining, committed and free are always exact. Low-stock warnings by roll and by material total tell you when to reorder. See the detail on filament tracking.
One form to add a job with a single print or many. Colours pull from your live stock. Combine parts from any job onto a multi-part plate with a per-part gram share for a fair cost split. Import a .gcode.3mf to auto-fill grams and duration.
Best-fit roll packing with a roll-over ladder: explicit roll, then loaded roll, then next matching in-stock roll, then a clear "need to buy". A per-printer calendar with drag-to-schedule, overlap detection and a "what can I print now" view.
Finish a job, confirm the actual grams, and write exactly one ledger deduction at a frozen unit cost. A 50 g PLA print at £20 per kilogram costs about £1 in filament, and the app never double-counts a gram. Plate splits, spend reports and CSV export included.
Per-printer timers on both run-hours and calendar days, with editable current hours and sensible default intervals you can reset. A daily check flags what is due, so a nozzle clean or belt tension never slips past you.
Low-stock and maintenance alerts keep you ahead of a stalled print. Every finished job is logged to a searchable print history with grams, cost and failures, ready to filter and export whenever you need the numbers.
SpoolBoard is deliberately narrow. It does the planning and record-keeping well and stays out of the way of the tools you already trust.
This is not slicing software. You keep using Bambu Studio, PrusaSlicer, OrcaSlicer or Cura to prepare a print. SpoolBoard picks up from there, holding the job, the filament and the cost so nothing lives in your head or a spreadsheet.
There is no printer to pair and no brand requirement. Log a print by hand in seconds or import a .gcode.3mf file. It works the same whether you run one Ender or a shelf of Bambu Lab and Prusa machines.
SpoolBoard is a progressive web app you install to your phone home screen with no app store. It is built to use standing at the printer, with quick logging and a single-printer day view that fits a small screen.
SpoolBoard does not watch your printer or read a live scale. It keeps an append-only record you confirm yourself, which is why the numbers stay trustworthy and match what actually left the spool.
Planning, filament tracking and honest costing in one place. Start a 14-day free trial with no card, then continue from £3.99 a month. Compare plans on the pricing page.

No. SpoolBoard does not slice models or send files to your printer. It sits next to your slicer and printer, handling the planning, filament tracking and costing that slicers leave out. You keep using Bambu Studio, PrusaSlicer, OrcaSlicer or Cura exactly as you do now.
Yes. SpoolBoard is not tied to any hardware, so it works with Bambu Lab, Prusa, Creality, Voron, Anycubic and any other brand. You log jobs by hand or import a .gcode.3mf file to auto-fill grams and duration. There is no printer to connect and no lock-in.
SpoolBoard starts with a 14-day free trial and no card required, so you can try every feature first. After the trial it is a paid app from £3.99 a month. That keeps it small, ad-free and independent rather than free with your data as the price.
Yes. Filament is tracked by the gram on every spool, with remaining, committed and free stock always exact. Every finished print is written to an honest ledger, so your print history shows what you made, what it weighed and what it cost, ready to export as CSV.
Yes. SpoolBoard is a mobile-first progressive web app, so it runs in the browser and installs to your phone home screen with no app store. It is built to use standing at the printer, with a single-printer day view and quick logging on a small screen.
It is built for honest print costing rather than guesswork. A 50 g PLA print at £20 per kilogram is about £1 in filament, and SpoolBoard freezes that unit cost at completion, adds plate splits and spend reporting, and never double-counts a gram. Try the free cost calculator to see the maths.
