Filament Cost Per Part with total filament cost of 21 $: a worked example
Suppose total filament cost falls to 21 $. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate FDM filament cost per printed part from total filament spend, accepted parts, and any conversion factor.
The inputs for this scenario
- Total filament cost: 21 $ (the input this scenario stresses; the baseline uses 42)
- Accepted printed parts: 36 parts (held at the documented default)
- Cost conversion factor: 1 x (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Raw filament cost per part = total filament cost รท accepted printed parts.
- Filament cost per part works out to 0.58 $ / part at these inputs, and this is the headline figure for the scenario.
- Raw material cost per part works out to 0.58 $ / part at these inputs.
- Cost conversion factor works out to 1 x at these inputs.
- Accepted printed parts works out to 36 parts at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where total filament cost sits at 42 $ and the headline result is 1.17 $ / part, this scenario comes in 50% below the baseline at 0.58 $ / part.
- It divides total filament cost by the number of accepted printed parts, then scales by a conversion factor. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
Results at a glance
- Filament cost per part: 0.58 $ / part (headline result)
- Raw material cost per part: 0.58 $ / part
- Cost conversion factor: 1 x
- Accepted printed parts: 36 parts
Run it with your numbers
