3D Printing Sensitivity Analysis Calculator Examples
Worked commercial 3D printing examples showing how volume, pricing, material costs and print failures can change monthly profit.
These examples illustrate how the calculator treats successful output, revenue, variable costs and fixed costs. They are planning estimates using average job values rather than forecasts or business advice.
Growth scenario with improved quality
A print service starts with 500 attempted jobs, then expects 10% more volume, a 5% price increase and failure rate improvement from 8% to 5%.

500/month
Scenario jobs
550/month
Scenario successful jobs

Scenario revenue

Scenario profit
$18,400

$18,400
3D Printing Sensitivity Analysis Calculator
The scenario produces $18,400 monthly profit and a 41.9% profit margin.
Volume growth with unchanged quality
A shop attempts 300 jobs per month at a 10% failure rate and expects volume to rise 25%, with no price or cost changes.
Input Summary
Baseline jobs
300/month
Scenario jobs
375/month
Selling price

Variable cost
$25/attempted job
Fixed costs

3D Printing Sensitivity Analysis Calculator
The volume-growth scenario results in projected profit of $5,875 per month.
Material cost increase and higher failures
An operation attempts 400 jobs at $100 per successful job, with $30 material cost, $15 other variable cost and $10,000 fixed costs. Material cost rises 20% and failure rate increases from 5% to 12%.
Input Summary

$4,800
3D Printing Sensitivity Analysis Calculator
Projected monthly profit is $4,800, compared with a baseline profit of $11,500 under the original 5% failure rate and $30 material cost.
How to Read Your Results
Projected successful jobs are saleable output after allowing for the scenario failure rate.
Projected profit is the amount remaining after estimated variable and fixed costs; it is not cash flow or taxable income.
A positive profit change means the scenario outperforms the entered baseline; a negative value means it underperforms it.
Profit margin shows projected profit as a percentage of scenario revenue and may be negative when projected costs exceed revenue.
Assumptions & Important Notes
- The inputs are monthly averages and the job mix is broadly consistent within each scenario.
- Revenue is recognized only for successful, saleable jobs.
- Variable costs are charged per attempted job, while fixed costs are unchanged.
- Examples exclude taxes, financing, capital purchases and timing differences in customer payments.

Frequently Asked Questions
Can these examples be used for a print farm?
Yes, if the entered job, cost and failure-rate averages represent the combined operation. Separate models may be clearer for materially different machines or product lines.
What happens if projected volume falls?
Enter a negative volume change. The calculator reduces attempted jobs while holding fixed monthly costs unchanged.
Should the selling price include shipping?
Use a consistent approach. If shipping revenue is included in price, include the matching variable shipping cost where applicable.
Do fractional successful jobs mean the calculation is wrong?
No. Fractional jobs represent an average expected output across a month; the calculator does not round the underlying estimate.
