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.
