Print farm calculator
If you sell prints, the numbers that matter are throughput and margin. Set your printers, hours, part time and price to see monthly output and profit.
This ignores idle time, maintenance and shipping. It assumes parts are printed back to back, which is only true if you always have work queued.
Reading the numbers
The model is deliberately simple: each printer runs for the hours you give it, each part takes a fixed time, and a failure rate removes some output. Output per printer per day = (hours ÷ part time) × (1 − failure rate).
In practice, idle time is the biggest gap between the model and reality: overnight jobs, plate changes and waiting for orders all cut into it. Treat the result as a ceiling, then discount it.

FAQ
Is a print farm profitable?
It can be, but only with consistent demand. Printing is the easy part; selling enough to keep the machines busy is what decides the profit.
Should I count printer depreciation here?
Use the cost calculator per part to include machine wear, then enter that figure as cost per part here.
