3D Printing Seed (Small-Scale) Calculator Examples
Worked examples show how startup costs, sales assumptions, runway and contingency affect a small 3D printing funding target.
These examples use the calculator’s planning logic: estimate gross profit, fund any monthly shortfall for a chosen runway, then add a contingency buffer. Amounts are illustrative and shown in dollars only for readability.

How to Read Your Results
The seed funding target includes upfront costs, modeled cash runway and a contingency buffer.
Startup costs are paid before or around launch; they are separate from recurring overhead.
Monthly cash burn is the projected shortfall after estimated gross profit, not after total sales.
A zero cash-burn result means the model projects gross profit at least equal to monthly operating costs.
Test conservative sales and margin assumptions to understand how sensitive the funding target is.
Assumptions & Important Notes
- Examples treat gross margin as the amount remaining after direct job costs.
- All figures are illustrative estimates, not pricing or funding recommendations.
- The modeled runway starts from launch and uses a constant monthly shortfall.
- Taxes, financing costs and owner compensation are excluded unless included in operating costs.

Frequently Asked Questions
Can I use the calculator for a 3D printing side business?
Yes. Include only the costs and sales relevant to the side business, and decide whether owner pay needs to be funded.
Should I test more than one sales estimate?
Yes. A cautious, expected and stronger sales case can show how much the funding target depends on demand.
Does a positive monthly projection mean no cash reserve is needed?
Not necessarily. The calculator sets modeled runway funding to zero, but delayed sales, repairs and changing costs can still affect cash needs.
