Selection logic
Decision guide
How to choose the right otoplastics resin
Select the most suitable grade according to whether your priority is fit precision, rigidity, flexibility or overall comfort and usability in the final part.
Decision guide
-
Need maximum fit accuracy → prioritize high-resolution, dimensionally stable materials
-
Need rigid shells → select materials with higher hardness and structural stability
-
Need flexible or comfort-oriented parts → choose softer or elastomeric grades
-
Need prototypes and validation → select materials aligned with workflow testing and iteration needs
Workflow principle
Fit and performance depend on the full workflow
Final performance depends on printer calibration, layer resolution, post-processing, polishing and the specific requirements of the audiology workflow.
These materials should be interpreted as part of a controlled manufacturing process where geometry, comfort, durability and fit must be validated together.
Regulatory positioning
3Dresyns otoplastics materials are supplied as professional manufacturing materials for additive manufacturing workflows in audiology and custom-fit environments.
These materials are not marketed as finished medical devices unless explicitly stated for a specific product and jurisdiction. The regulatory classification, validation and compliance of any final device manufactured using these materials remain the responsibility of the legal manufacturer of that device.
These materials are intended for audiology and custom-fit workflows. Final suitability depends on geometry, fit requirements, post-processing, comfort criteria and the specific use environment.
These products should be understood as engineering materials for otoplastics and audiology workflows. Final validation must always consider fit accuracy, mechanical behavior, user comfort and application-specific constraints.
