3D Print Failure Rate uses failed prints, total prints.
Making a print estimate reflect the work behind the part
For 3d print failure rate, the relationship is Result = (([Failed prints]) ÷ ([Total prints])) × 100. The amount depends on the supplied failed prints, total prints, rather than a live market price or a value imported from another record. Filament cost is only one component of a printed part. Machine time, failed jobs, setup, labour and fulfilment can materially change contribution. Compare grams with the usable spool weight, rather than the label price alone.
What the model includes
Result = (([Failed prints]) ÷ ([Total prints])) × 100 Use measured print duration where possible and keep machine-hour charges separate from electricity. If the machine rate already includes energy or labour, entering those amounts again double counts them. The model cannot infer a failure rate from a successful test print. A quote still needs the part requirements and production method. Material choice, orientation and finishing affect quality; this estimate does not establish mechanical suitability or guarantee the print will succeed.
Example with the supplied inputs
Failed prints: 2; Total prints: 50. Result: 4.00%. The values are illustrative.
Compare one changed input
Failed prints changes from 2 to 2.2. The result becomes 4.40%. All other inputs remain fixed.
Calculation rule
Result = (([Failed prints]) ÷ ([Total prints])) × 100
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Failed prints | 2 | Use the source quantity represented by failed prints. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Total prints | 50 | Use the source quantity represented by total prints. Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 4.00% is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Failed prints, Total prints. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Failed prints on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 4.00%.
Change Failed prints from 2 to 2.2 while keeping every other value fixed. The result becomes 4.40%. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
