Additive Manufacturing or 3D printing has been a hot topic with many new developments the last 20-30 years and still is. Even though its many advantages like low material usage, sustainability and great variety of producible shapes, injection molding is often still the preferred manufacturing method due to considerably lower prices per unit for large batch sizes. Additive manufacturing is often seen as prototyping method. I want to share why this is not the case in parts of the hearing aid industry, show you how such parts are produced and why additive manufacturing is the method of choice here.
