The short answer
A print farm is several 3D printers, usually of one or two models, used to produce parts or products repeatedly. What makes it a farm rather than a room with printers is the organisation: standard sliced files per printer model, a shared print queue, controlled materials and a routine for removing and checking parts.
What print farms make
- Products sold online: keychains, holders, organisers, cosplay parts, spare parts.
- Short production runs and parts for other companies.
- Prototypes and fixtures for engineering teams.
- Educational and maker projects at schools and makerspaces.
What a print farm needs
- Reliable printers, ideally a small number of models, with spare nozzles and build plates.
- Dry, organised filament storage and a way to know what is loaded where.
- A stable local network and fixed IP addresses for the printers.
- Software that queues plates, starts them on free printers and tracks results, stock and orders.
- A daily routine: remove parts, check quality, confirm the bed is clear, pack and ship.
How big is a print farm?
There is no minimum. Many farms start with two or three printers next to a shop on Etsy, Allegro or WooCommerce and grow to tens of printers. The way of working matters more than the number: once files, materials and the queue are standard, adding a printer adds capacity without adding chaos.
How Farmit fits in
Farmit is software for exactly this: it connects Bambu Lab, Prusa, Klipper and OctoPrint printers through one gateway, keeps one queue across them, starts plates under your rules and connects production to stock and shop orders.
Questions
Is a print farm profitable?
It can be when products sell steadily and the cost per part is known. Material, electricity, machine wear, labour, failures and platform fees all count; the guide on pricing 3D prints walks through them.
Do I need special printers?
No. Most farms use ordinary consumer printers. Enclosed printers help with ABS and ASA, and fewer different models make the farm easier to run.
