Additive Manufacturing Service Bureau Quoting calculator
Service Bureau Capacity Calculator
Service bureau capacity is the number of good, shippable parts your print farm can realistically produce in a planning period once printer downtime and inspection rejects are taken out. Quoting and scheduling teams use it to commit lead times they can actually hit, to know when to turn work away or outsource, and to size a fleet against a sales pipeline. The trap is quoting from gross nested capacity; a build plate that holds 48 parts across 14 cycles looks like 672 parts, but uptime and yield quietly erase a meaningful slice of that. This tool exposes the realistic good-part number.
What this calculator does
- Estimate good service bureau output from parts per build cycle, available build cycles, printer uptime, and accepted yield.
- a production scheduler needs expected good parts for a quote window or delivery promise
- It computes deliverable good-part capacity by taking gross nested capacity and discounting it for printer uptime and post-inspection accepted yield.
Formula used
- Gross service bureau capacity = parts per cycle × available build cycles
- Good quote capacity = gross capacity × printer uptime × accepted part yield
Inputs explained
- Good parts nested per build cycle:
- Build cycles available in the period:
- Printer uptime / availability:
- Accepted part yield after inspection:
How to use the result
- Use it during capacity planning, when committing a delivery date on a large order, or when deciding whether to add a printer versus outsource overflow.
- It treats one representative parts-per-cycle and yield across all builds; if your part mix swings between dense small parts and large single-piece builds, run it per product family rather than as a fleet average.
Current U.S. benchmarks
- The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
- The U.S. prime lending rate is 6.75% (Federal Reserve via FRED, 2026-07-02). Payback and financing math should start from today's rate, not a remembered one.
Common questions
- How do you calculate 3D print farm capacity? Multiply parts per build cycle by available cycles for gross capacity, then multiply by uptime and accepted yield. With 48 parts over 14 cycles at 88% uptime and 94% yield, gross is 672 and good quotable capacity is about 556 parts.
- Why is good capacity lower than gross build capacity? Printers are not available 100% of the time and not every part passes inspection. In the example, 88% uptime removes about 81 parts and a 94% yield removes roughly 35 more, dropping 672 gross to 556 good.
- What is a realistic uptime for an SLS or resin print farm? Well-run fleets see 80-90% uptime once you account for recoat errors, recoater blade swaps, calibration and unplanned faults. The 88% in the example is a healthy but not heroic figure; new or under-maintained machines often sit at 70-80%.
- Should I quote lead times off gross or good capacity? Always off good quotable capacity. Quoting the 672 gross number will overcommit by roughly 116 parts in this scenario and put you behind on delivery the moment uptime or yield dips.
- How do I lift my service bureau capacity? Densify nesting to raise parts per cycle, add cycles by shortening turnaround or adding shifts, lift uptime through preventive maintenance, or improve yield through better orientation and support strategy. Yield and uptime compound, so a few points on each move the good-part number noticeably.
