Additive Manufacturing calculator
Parts Per Build Calculator
Parts per build determines how many sellable parts a machine can deliver from a nesting plan. This calculator converts nested capacity and available builds into good output after uptime and yield losses.
What this calculator does
- Estimate good parts per additive build from nested capacity, scheduled builds, machine uptime, and print yield.
- a production manager needs expected good part output from one machine or process window
- Returns expected accepted parts from the planned additive builds.
Formula used
- Gross parts = nested parts per build × available builds
- Good parts = gross parts × machine uptime × expected print yield
Inputs explained
- Nested parts per build: undefined
- Available builds: undefined
- Machine uptime: undefined
- Expected print yield: undefined
How to use the result
- Use it for production commitments, backlog planning, and deciding whether another build is needed.
- It assumes the same nest capacity across builds and does not model material changes, maintenance, or post-processing bottlenecks.
Common questions
- Should failed starts reduce uptime or yield? Use uptime for lost machine availability and yield for completed parts that fail or are rejected.
- Can I use this for multiple machines? Yes if the entered builds and uptime represent the combined machine group.
- What if nests vary by part mix? Calculate each nest separately or use a conservative average nested parts per build.
- What decision does the result support? It shows whether planned builds can cover customer demand with expected good parts.
