Temperature-responsive shape recovery
TC-85 specimens showed recovery toward their original form at 37°C under the reported test conditions.2
Product information
Printed as the aligner. Not formed over a model.
SmartAligners use Graphy's directly printable orthodontic material. The appliance is designed digitally, printed in its final geometry and completed through a controlled post-processing workflow.1

01 / Manufacture
The appliance comes directly from its digital design.
Traditional clear-aligner production commonly thermoforms a plastic sheet over a model. Direct printing removes that model-forming step. Published laboratory work reports that thermoforming can alter material thickness and geometry; direct printing creates a different production route, but its result still depends on validated print and post-processing controls.2

Design the appliance
Stages, thickness and any designed pressure features are reviewed digitally.

Print directly
The aligner is printed from the appliance file rather than formed over a separate model.

Graphy's stated workflow includes excess-resin removal, nitrogen curing, finishing and quality control.1

Shape memory describes a material response, not a guaranteed smile result.
In a 2022 laboratory study, TC-85 specimens recovered toward their original form at 37°C after controlled deformation. The authors also reported different viscoelastic and thickness behavior from the PETG control.2
The study was a material test, not a randomized patient trial. Clinical movement still depends on diagnosis, staging, biology, wear and review.
Evidence, with context
What is supported, and how strongly?
The label beneath each point matters as much as the claim itself.
Designed thickness can change force systems
A sensor-based study found that selectively changing direct-printed aligner thickness altered measured forces and moments.3
Promising technology, developing clinical evidence
A 2023 review described direct-printable orthodontic materials as an active area of research and called for stronger standardized and clinical evidence.4
What this website does not claim
It does not promise faster treatment, less pain, no refinements, no attachments, or a particular result before clinical assessment. Product properties and patient outcomes are not the same thing.
