How to Read Your Results
Material efficiency shows the percentage of expected filament consumption retained in the final model; higher values mean less non-model material per completed part.
Expected total material is an average estimate per completed model, not the filament used by every individual attempt.
Expected material waste includes supports, purge material and an allowance for failed attempts.
Expected total job time combines adjusted machine printing time with one-time setup and post-processing time.
Compare scenarios using the same model and quality target; otherwise a lower material figure may reflect a different part or finish.
Assumptions & Important Notes
- All material figures are filament weights in grams.
- The stated failure rate is representative of similar jobs, not a guarantee for the next attempt.
- A failure consumes an average full attempt's material and machine time.
- Setup and finishing time applies once for each completed model.

Frequently Asked Questions
How can I estimate filament needed for a print with failures?
Add model, support and purge material for one attempt, then divide that total by one minus the failure rate expressed as a decimal.
Should purge tower material be counted as waste?
Usually, yes. If it does not become part of the completed model, include it as purge and priming material.
Why does a long print have lower time efficiency in the example?
The example uses a higher failure rate. Reprints increase expected machine hours, while setup time adds a further non-productive time component.
Can I use these examples for resin printing?
The same expected-success logic can be useful, but resin supports, wash losses and failed-print behavior may need different inputs and assumptions.
