3D Printing Labour Calculator
Estimate the labour time and labour cost of a 3D print run using setup, monitoring, post-processing and hourly labour rates.
Overview
This 3D Printing Labour Calculator estimates the hands-on time and labour cost for a print run. Enter the number of parts, print time, setup time, active monitoring share, post-processing time and hourly labour rate to estimate the labour cost per part and for the full job.
How it works
The calculator separates machine runtime from human labour. It applies setup time once, estimates active monitoring as a percentage of total machine print time, and adds post-processing time for every part. These hands-on hours are multiplied by the hourly labour rate. Dividing the total by the number of parts gives the average labour cost per part.
How to use this calculator
- 1Enter the number of identical parts in the print run.
- 2Add the expected print time for one part.
- 3Enter the one-off setup time for preparing the printer and job.
- 4Choose the percentage of print time that needs active monitoring.
- 5Add finishing and post-processing time for each part.
- 6Enter your hourly labour rate and review the estimated labour cost.

For 10 parts taking 3 hours each, with 30 minutes of setup, 5% active monitoring and 15 minutes of finishing per part, the estimate is 4.5 labour hours and a total labour cost of 112.50, or 11.25 per part.
Frequently asked questions
What counts as 3D printing labour?
Labour is the hands-on work needed to prepare, start, monitor, remove, finish, inspect and package a print. Unattended printer runtime is not normally treated as labour unless someone must actively supervise it.
Should I charge for machine print time as labour?
Usually, machine runtime is priced separately as machine overhead or a printer hourly rate. This calculator only includes the portion of runtime entered as active monitoring labour.
How do I estimate post-processing time?
Time one or more representative parts from removal through final inspection. Include support removal, washing, curing, sanding, assembly and packing that your job requires, then use an average per part.
Why is the labour cost per part lower for larger batches?
One-off setup time is spread across more parts. If the parts have identical finishing needs, the per-part cost falls as the batch grows, although post-processing still rises with quantity.
Does this calculator include filament, resin or electricity?
No. It estimates labour only. Add material costs, power, consumables, machine overhead, waste allowance and shipping separately when building a full print quote.
What hourly labour rate should I use?
Use a rate that reflects the cost or price of the person doing the work. Depending on your purpose, this may include wages, employment costs, workshop overhead and a margin.

Assumptions and warnings
Assumptions
- All parts use the same print time and post-processing time.
- Setup time is applied once to the complete print run.
- The monitoring percentage represents active labour time rather than unattended machine runtime.
- The hourly labour rate includes only the costs you intend to recover through labour.
- This estimate excludes material, electricity, machine depreciation, maintenance, shipping and failed-print costs unless you include them separately.
Warnings
- This calculator provides an estimate only; actual labour can vary with printer reliability, part complexity, finishing standards and reprints.
- Review your labour rate and post-processing allowance before using the result for a customer quote or production decision.
