How do you calculate nesting yield?

Divide usable nested parts by the requested or theoretical part count for the build. With 86 usable parts out of 100 theoretical, nesting yield is 86%.

What is a good nesting yield for SLS or MJF?

Strong powder-bed bureaus run 80-90% volumetric packing on well-mixed jobs; 86% in our example is solid. Single-part-geometry jobs often pack lower because of orientation constraints.

What does the gap to target mean?

It's your target minus actual, in percentage points. At an 85% target and 86% actual the gap is -1 point — you beat target by one point, so the negative sign means you're ahead.

How is nesting yield different from build success rate?

Nesting yield is about packing density before printing; build success rate is how many of those packed parts come out conforming. You need both to know true cost per good part.

Why does low nesting yield raise my price?

Fixed build cost — machine time, warm-up, inert gas, cool-down — is spread over fewer parts when yield is low, so each part absorbs more cost and your quote climbs.

Can nesting yield exceed 100%?

Against a fixed theoretical count, no. But if 'requested' parts is a customer order quantity and you over-pack to bank spares, your usable count can exceed the request and yield can read above 100%.

Nesting Yield Calculator

Nesting yield measures how many good, usable parts you actually pack into a build relative to the theoretical or requested part count for that platform. Build planners and estimators at powder-bed and resin bureaus live by it because every empty pocket on a plate is machine time and powder you paid for but can't bill. A high nesting yield spreads fixed build cost across more parts and directly lowers your per-part price. This calculator returns the yield percentage and the point gap to whatever target your shop runs.

What this calculator does

Calculate usable nested parts as a percentage of requested parts or theoretical build capacity for quote planning.
an AM estimator needs to know whether a build nest is efficient enough to support the quoted price
It computes nesting yield as usable parts over requested or theoretical parts, and the point gap to your target yield.

Formula used

Nesting yield = usable nested parts ÷ requested or theoretical parts
Gap to target = target nesting yield - actual nesting yield

Inputs explained

Usable nested parts:
Requested or theoretical parts:
Target nesting yield:

How to use the result

Use it after laying out a build in your nesting software to confirm packing density before committing machine time, or to grade historical builds.
Yield alone ignores part orientation quality — a tightly packed plate that produces warped or weakly-sintered parts is a false win, so pair it with scrap rate.

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.
