Inkjet 3D resins for printing Otoplastics
Professional inkjet photopolymers for otoplastics, audiology and custom-fit ear-related workflows. This collection is positioned around surface quality, fit-focused printing, controlled mechanical response options from rigid to flexible where applicable, and workflow suitability for hearing-related geometries.
This collection groups the 3Dresyns® otoplastics inkjet materials intended for earmolds, hearing-related custom-fit parts, audiology prototyping and patient-fit geometries where surface finish, fit precision and controlled mechanical response are especially important.
Key features & benefits
- otoplastics-oriented material selection
- surface quality and fit-focused printing
- controlled mechanical response options from rigid to flexible where applicable
- workflow suitability for hearing-related geometries
- professional inkjet route for custom-fit audiology environments
Why choose this collection
Designed for custom-fit ear geometries
This collection is not positioned as a general-purpose inkjet family, but as a more specific route for otoplastics workflows where fit, contour fidelity and patient-related geometry matter.
Mechanical range from rigid to soft
The visible portfolio spans ultra-hard and tough, ultra-hard and flexible, and soft material options, allowing a more practical match between geometry, handling and intended audiology workflow.
Better fit for audiology and hearing-related workflows
This collection is particularly relevant for earmolds, hearing aid shells where applicable, otoplasty prototypes and patient-fit components that require a more specialized custom-fit material route.
Typical applications
- earmolds
- hearing aid shells where applicable
- otoplasty prototypes
- patient-fit components
- audiology workflow parts
Selection summary matrix

Portfolio overview
Rigid otoplastics route
OTO-UHT Bio provides the ultra-hard and tough route inside the collection for hearing-related parts where more structural stability and rigid custom-fit behavior are preferred.
Intermediate firmness/flexibility route
OTO-UHF Bio extends the family toward a firmer-but-more-compliant option, useful where the part needs controlled flexibility without moving fully into soft behavior.
Soft patient-fit route
OTO-S provides the softer route in the collection, positioned for custom-fit geometries and more comfort-oriented otoplastics applications where a more compliant response is beneficial.
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.
