3D Printing Yield Calculator Examples
Worked examples show how model volume, infill, waste, and spool weight affect filament use and estimated output.
These examples use the calculator's simplified volume-based method. They illustrate small prototypes, a batch run, and a larger part with a more conservative waste allowance.
Small PLA prototype
A hobby print with modest shell material and a 10% waste allowance.
Input Summary
Model volume
30 cm³
Infill / shell material
15% / 15%
Density / waste
1.24 g/cm³ / 10%
Spool weight
1,000 g

- 2Material per part30 × 0.30 × 1.24 × 1.1012.3 g
- 3Spool yieldfloor(1000 / 12.3)81 parts
Result Summary
Spool yield
81 parts
3D Printing Yield Calculator
The estimate is 12.3 g per prototype and about 81 complete parts per 1 kg spool.
Batch of functional PLA brackets
A planned run where total material is more useful than a single-part estimate.
Input Summary
Model volume
50 cm³
Infill / shell material
20% / 15%
Density / waste
1.24 g/cm³ / 10%
Batch size

- 3Batch material23.9 × 10238.7 g
Result Summary
Batch material
238.7 g
3D Printing Yield Calculator
Ten brackets require approximately 238.7 g of filament.
Large PETG enclosure with extra allowance
A cautious estimate for a 750 g usable PETG spool.
Input Summary
Model volume
180 cm³
Infill / shell material
25% / 20%
Density / waste
1.27 g/cm³ / 20%
Spool weight
750 g
Calculation Breakdown

- 3Spool yieldfloor(750 / 123.4)6 parts
Result Summary
Spool yield
6 parts
3D Printing Yield Calculator
The enclosure uses about 123.4 g per part, for an estimated yield of 6 parts.
How to Read Your Results
Filament per part includes the waste allowance and is useful for comparing variants of one design.
Total filament required is the estimated material for the selected number of identical parts.
Spool yield counts complete parts only, so it is always rounded down.
A negative spool remaining result means the planned batch exceeds available usable filament.
Assumptions & Important Notes
- Model volume is entered in cm³ and represents a fully solid part.
- Shell material is a percentage-based approximation rather than a slicer geometry calculation.
- The same settings and material are used for every part in a batch.

Frequently Asked Questions
How many 3D prints can I get from a 1 kg spool?
It depends on grams required per part. Divide 1,000 g by the per-part estimate and round down.
How do I estimate filament for multiple identical parts?
Calculate grams per part including waste, then multiply by the number of parts.
What if each part has different supports?
Estimate each design separately or use slicer estimates for each print.
Can I use the examples for ABS, PETG, or TPU?
Yes, but replace the density with the value for the actual filament and adjust waste as needed.
