How do you calculate aligner build cost?

Multiply the number of aligners by the variable cost per aligner, then add setup and lab overhead. For 100 aligners at $2.50 each plus $75 setup and $25 overhead, total build cost is $350 and cost per aligner is $3.50.

What is a good cost per aligner for an in-house lab?

Mature in-house thermoforming labs typically land between $2 and $6 per aligner depending on material and automation. The $3.50 in our example is competitive; per-aligner cost above $8 usually signals batches that are too small to absorb setup.

Why does cost per aligner drop as the build gets bigger?

Setup, labor, and overhead are fixed per build. Spreading the $100 of fixed adders over 100 aligners adds $1.00 each; over 300 aligners it would add only $0.33, pulling the per-aligner cost down toward the $2.50 variable floor.

Does this cost include the printed dental model?

Only if you include the model resin and print time in the variable cost or setup line. Many labs track model print cost separately, so add it to either field if you want a fully loaded per-aligner number.

Should I quote per aligner or per case?

Quote per case to the doctor, but manage margin per aligner internally. The total build cost ($350 here) is what you bill against; the $3.50 per-aligner figure is what you benchmark and improve.

In-house aligners vs outsourcing: which is cheaper?

Compare your fully loaded cost per aligner against the vendor's per-stage price. If outsourced stages run $9-15 each and you produce in-house at $3.50, in-housing wins once volume covers your printer and former amortization.

Dental, Orthodontic & Prosthetics Manufacturing calculator

Aligner Build Cost Calculator

The Aligner Build Cost metric tells a clear-aligner lab exactly what one print-and-thermoform build costs in total dollars and per aligner. Treatment planners, lab managers, and DSO procurement teams use it to price cases, decide make-vs-buy against outsourced aligner vendors, and set per-stage transfer pricing. Because aligner builds carry a fixed setup burden (model nesting, plate loading, trim-line approval) spread across many stages, the per-aligner number swings hard with batch size — which is exactly what this calculator exposes. Knowing the true per-aligner cost is what separates a profitable 3-arch case from one you lose money on.

What this calculator does

Estimate the total cost and cost per aligner for a thermoformed or printed aligner build, including appliance count, per-aligner material and labor, setup, and handling burden.
Use it when aligner build cost in dental, orthodontic and prosthetics manufacturing is being quoted and you need a number you can defend on a phone call.
It computes the total dollar cost of a single aligner build and the resulting cost per aligner by combining variable per-piece cost with fixed setup, labor, and overhead.

Formula used

Total aligner build cost = aligners in build × variable cost per aligner + case or batch setup cost + additional lab labor and overhead
Cost per aligner = total aligner build cost ÷ aligners in build

Inputs explained

Aligners in build:
Variable cost per aligner:
Case or batch setup cost:
Additional lab labor and overhead:

How to use the result

Use it when quoting a new case, comparing in-house thermoforming to an outsourced aligner supplier, or deciding whether to merge small cases into one nested build.
It assumes every aligner in the build is usable; scrapped stages from failed forming, warped models, or trim errors raise the real per-aligner cost above the figure shown.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
The U.S. has 8,825 medical equipment and supplies establishments employing about 308,388 workers (Census County Business Patterns, 2023).
