3D Printing Labour (Seasonal) Calculator FAQ
Answers to common questions about estimating 3D printing labour cost, seasonal workload, payroll burden and peak FTE capacity.
This FAQ explains the calculator inputs, the seasonal workload method and how to interpret labour cost and staffing-capacity estimates for a 3D printing operation.
General calculator questions
Basic questions about what the calculator estimates and where it can be used.
What does the 3D Printing Labour (Seasonal) Calculator estimate?
It estimates annual hands-on labour hours, annual loaded labour cost, off-peak and peak-month labour hours, and peak full-time-equivalent capacity.
Who can use this calculator?
It can be used for planning estimates in small print shops, internal production teams, prototype operations and other workflows that handle recurring 3D print jobs.
Is this a full 3D printing cost calculator?
No. It focuses on direct labour and seasonal workload. It does not calculate materials, machine ownership, energy, rent or shipping costs.
Can the calculator be used for custom and repeat print jobs?
Yes, provided labour hours per job represent a reasonable average for the mix of work expected.
Inputs and labour time
Questions about entering production volume, labour time and employee capacity.
What is a print job in this calculator?
A print job is one completed unit of work counted in your annual production plan. Define it consistently, such as one order, build plate or completed part batch.
Should I include machine setup in labour hours per job?
Include setup if it requires employee time and is part of the work you want to cost. The same applies to finishing, inspection and packing.
Should unattended print time be included?
Usually not, unless an employee must actively attend the printer during that time. The calculator is designed for labour time rather than machine runtime.
What are productive hours per employee per month?
They are the labour hours assumed to be available for the production work being planned. This may be lower than total paid or scheduled hours.
Seasonality and staffing capacity
Questions about peak demand settings and the FTE result.
How does the peak demand multiplier work?
It sets peak-month jobs relative to an off-peak month. A multiplier of 1.5 means a peak month is estimated to have 50% more jobs than a normal month.
Why are off-peak monthly jobs lower when I increase the peak multiplier?
The calculator holds total annual jobs constant. More work assigned to peak months leaves fewer jobs to allocate to the normal months.
What does peak FTE mean?
Peak FTE is peak-month labour hours divided by productive hours per employee per month. It expresses workload as a full-time-equivalent capacity amount.
Does peak FTE include overtime or absence coverage?
No. It is based only on the productive monthly hours you enter. Adjust your input or assess additional contingencies separately if those factors are relevant.
Costs and accuracy
Questions about payroll burden, cost coverage and practical accuracy.
What is included in the loaded hourly labour cost?
It includes the base hourly wage plus the payroll burden and benefits percentage entered in the calculator.
What can payroll burden include?
It can be an estimated allowance for employer-paid costs such as payroll taxes, insurance, benefits and paid leave. Relevant costs vary by location and employment arrangements.
Why might actual labour cost differ from the estimate?
Actual results can differ because of job complexity, failed prints, rework, training, overtime, employee availability, changing pay rates and workflow interruptions.
Does the result include contractor or temporary labour rates?
Not automatically. Use an hourly rate and burden assumption that reflect the labour arrangement you are estimating.
How is annual 3D printing labour cost calculated?
Annual jobs are multiplied by labour hours per job and then by the loaded hourly labour cost, which includes the selected payroll burden.
