In-office fabrication or manufacturing partner? The real math

The material of a single tray really does cost only a few euros; a cost analysis by our manufacturing partner therefore regards the aligner itself as the cheapest part of in-office fabrication. Anyone who concludes from this that in-house fabrication is a money-saver overlooks the fact that they are opening a small medical device production facility inside their practice, with everything that entails. This article runs the numbers, drawing on three sources: two cost analyses by the manufacturing partner and the first-hand account of a Spanish orthodontist who runs one of the country's largest orthodontic clinics and, at the same time, one of its most extensively equipped in-house setups.

The visible costs: equipment and software

Anyone serious about fabricating in the practice needs dental 3D printers, post-processing and curing units, thermoforming or pressure-forming machines, marking equipment, plus trimming and polishing stations. The range spans from a basic chairside setup in the low thousands to a complete line, for which $80,000 to $250,000 in equipment alone is the norm (industry estimate, as of 2026). On top of that come ongoing software licences, billed per case, per workstation or by subscription. According to this practitioner's assessment, independent planning solutions today cover around 98 % of clinically required functions, but demand more manual intervention and thus more clinician time.

The hidden costs: day-to-day operations

More interesting than the purchase is the daily routine. The practitioner's workshop numbers: a printed working model costs €0.40 to €1.80 depending on printer and resin class. Inexpensive printers allow open, low-cost resins but require constant staff attention: refilling, vat cleaning, recalibration, troubleshooting. Professional machines run more consistently but demand expensive proprietary resins. And: all printers eventually fail; anyone running volume needs duplicate machines, further increasing capital requirements and real unit costs.

The foil material typically comes in at €1 to €3 per aligner, multilayer foils for more consistent force delivery at the upper end, monolayer at the lower end. After thermoforming comes the most labour-intensive step: a trained assistant manages 45 to 50 aligners per hour with manual trimming, generally only with straight cut lines; scalloped trim lines are barely scalable by hand, and the finish rarely matches the quality of industrial laser trimming. Then: washing, curing, inspecting, sorting by patient and stage, bagging, labelling. As volume grows, this becomes a distinct operational burden.

The biggest item: regulation and responsibility

Aligners are medical devices. In-house fabrication means documented processes, quality control, traceability and ongoing staff time for quality management, in Europe within the framework of the MDR and ISO 13485. Calibration drift, material defects and capacity bottlenecks at peak times fall within your own area of responsibility, as does liability. This block appears in hardly any back-of-the-envelope calculation; in the manufacturing partner's analyses, it is the most frequently underestimated item.

The breakeven calculation

The formula is simple: breakeven cases = total fixed costs ÷ savings per case. The typical mistake is to use only the equipment list price as fixed costs. On this incomplete basis, industry guides cite a breakeven from around 20 to 30 aligner cases per month, with hardware amortisation in roughly 12 to 18 months. Factor in staff, software, downtime, machine duplication and compliance, and the true breakeven shifts significantly later, and most practices overestimate their future volume. The manufacturing partner's analysis concludes that in-house projects rarely fail on the workbench; they fail in the cost calculation.

The practitioner's verdict

The Spanish orthodontist's conclusion is remarkable precisely because he does not evaluate in-house fabrication in theory but runs it himself at scale: when staff and clinician time, equipment, maintenance, repairs, machine duplication and process friction are fully accounted for, the price per self-made aligner can match or even exceed outsourced fabrication. His recommendation for many clinics is a hybrid model: diagnostics and treatment planning stay in the practice, while fabrication is handled by a specialised partner who typically delivers industrially trimmed, sorted and labelled aligners within a week.

What this means for the decision

For practices with a consistently high, stable case volume, in-house fabrication can work, as a deliberately managed production operation with dedicated staff and a QMS. For the majority, the picture is different: with the partner model there is no capital outlay, costs accrue predictably per case (no costs without production), and the compliance burden of manufacturing rests with the certified manufacturer within the meaning of the MDR. Honestly calculated, the manufacturing partner's analysis finds that the comparison comes out clearly in favour of the partner model for the vast majority of practices. Role clarity remains essential: the manufacturing partner produces according to an approved plan; clinical control, plan approval and every therapeutic decision remain entirely with the treating dentist.
