Finished zirconia crowns on a dental lab workbench

Mill in-house or outsource to a milling center? The math that decides

Buying a CAD/CAM milling machine is one of the biggest investment decisions a lab can make. The right question isn't "can I afford it," it's "at what monthly volume does it pay off compared to outsourcing." The answer differs from lab to lab, but the method for calculating it stays the same.

How much outsourcing costs

Outsourcing milling centers publish real prices by tier. Economy zirconia: $15-22 per unit. Mainstream zirconia (ArgenZ or BruxZir tier): $28-40 per unit. Premium tier (e.max, custom abutments): $59-139 per unit. A 3-unit zirconia bridge averages around $102 total.

No upfront investment, no maintenance, no risk of the machine breaking down mid-delivery on a rush case. The cost is purely variable: zero units, zero spend.

How much milling in-house costs

Entry-level milling machines start around $30,000 (e.g. Roland DWX-52D), up to $70,000-100,000 or more for professional-grade models (Zirkonzahn M5, Arum 5X-500). On top of that come a scanner (around $10,500 for a lab unit) and software. The cost per unit drops as monthly volume rises, since the depreciation share spreads across more crowns.

The break-even point

The formula is simple: annual system cost divided by the savings per unit versus outsourcing. Move the sliders to see where your own break-even point falls.

Outsourcing wins (break-even at 50 units/month)

Example uses a $30,000 machine amortized over 5 years and $20/unit in-house material cost. Your real numbers depend on the machine model and your actual material costs.

What most calculations forget

An industry critic (Jim Downs DMD, Aesthetic Dentistry Magazine) pointed out that typical vendor claims, like "just 9 crowns a month pays for the machine," exclude labor, materials, software, and repairs. The math above is already more complete than most of what circulates in the industry, but it remains an example: your real material cost, staff training time, and machine downtime for maintenance need to be added case by case.
