Custom 3D Printed Titanium Earmolds for
Hearing Aids
The New Standard in Custom Hearing Solutions
Our custom 3D-printed earmolds for hearing aids combine high-tech titanium with a fully digital 3D printing process. The result is extremely precise, durable, and comfortable earmolds — ideal for modern, demanding hearing solutions.
Comfort
Ultra-thin walls create more space in the ear canal for the receiver.
Titanium’s lightweight nature makes the earmold barely noticeable in everyday use.
Skin-Friendly & Hygienic
Titanium is biocompatible, suitable even for sensitive skin and allergy sufferers.
Smooth, non-porous surfaces are easy to clean and disinfect, remaining hygienic over time.
Natural Acoustics
Thin yet stable walls reduce occlusion and support a more natural sound.
Geometry can be optimized for individual hearing devices and acoustic requirements.
Extremely Durable & Long-Lasting
Titanium maintains its shape, resists discoloration, and withstands sweat, earwax, and moisture.
High stability makes the earmolds virtually break-proof—ideal for active users and children.
Benefits for Audiology Labs and Clinics
With Our Complete Metal 3D Printing Ecosystem
Fully Digital Workflow
Replace traditional silicone impressions with digital ear scans and 3D data. Once captured, datasets can be stored, adjusted, and reproduced anytime — no new impressions required.
Unmatched Precision with 3D Printing
Custom earmolds are built layer by layer from titanium powder using metal 3D printing in the 2Create system. Results are reproducible within hundredths of a millimeter —each earmold is unique but produced at series quality.
Faster Turnaround & Predictable Costs
The digital workflow from scan to design to print reduces turnaround times. Standardized processes and high packing density in the build chamber lower unit costs and increase margins per run.

Easy Post-Processing in the Clinic
Titanium earmolds can be trimmed, adjusted, and polished with standard tools (Precision surface finishing with OTEC). Pressure points or minor adjustments can be made on-site without producing a new earmold.
Design That Impresses
Subtle or Statement-Making — Delicate construction allows for discreet, nearly invisible designs. On request, bold, visible designs can be created—from technical looks to jewelry-style aesthetics.
Surfaces & Finishes
Matte, polished, or color-accented: titanium earmolds can be tailored to the hearing device and personal style (Anodizing). This transforms the earmold for hearing aids from a functional aid into a premium, individual product.

Optimized for Titanium
fine-tuned process parameters the 2Connect parameter database ensure stable, reproducible quality for every custom earmold.
High Packing Density
Multiple individual earmolds per build.
Seamless integration
Direct processing of scan and STL data, automatic positioning in the build chamber.
Cost-Effective Production
Short build times, efficient powder use, and minimal post-processing reduce unit costs.
Production Workflow
for Custom Titanium Earmolds
The workflow for 3D printed titanium earmolds for hearing aids, combines state-of-the-art technologies. This is how custom-fit earmolds are created – from the digital ear scan, through CAD design, to 3D printing with the 2Create or 2Create Plus.
The subsequent post-processing includes stress relief in the oven, removal of the build platform and support structures, and precise, gentle surface polishing with OTEC, before the final assembly takes place.
Audio Workflow for 3D-Printed Titanium Hearing Aids Components
1. Ear Impression & Scanning
- 3D scan or traditional ear impression
- Creation of a precise 3D model of the ear canal
2. Digital Design / CAD
- Customization of the shell to anatomy and audio requirements
- Integration of electronic components (microphone, speaker, battery)
3. 3D Printing (Additive Manufacturing)
- Titanium laser melting for precise, individual housings
- Production of perfectly fitting custom earmolds for hearing aids
- 2Create and 2Create Plus Metal 3D Printers
- 2Build CAM Software with 2Connect Web Monitoring App
4. Post-Processing
- Heat treatment, removal of the build platform, and support structures
- Tumbling / Vibratory Deburring: removes burrs, residues, and edges
- Polishing: smooths the surface for comfort and aesthetics
- Precision surface finishing with OTEC
- Anodizing: protects the surface, enhances skin compatibility, and allows color options
5. Assembly
- Installation of electronics
- Final check of fit and seal
