Why ceramic 3D printing excels for fabricating earmoulds, and where does the opportunity lie?

If you’ve ever struggled to pick out a friend’s voice in a crowded room, imagine how much harder it is for someone with hearing loss. Conventional hearing aids often fall short — they can be affected by earwax buildup, discomfort, connectivity problems, and challenges with understanding speech in noisy environments. Surprisingly, one tiny component can make a big difference: the earmould. To understand how its design and manufacturing can overcome some of these challenges, we spoke with Dr. Daniel Bomze (Lithoz GmbH), Dr. Christoph Lauer (CADdent GmbH), and Jurij Belik (OC Otoplastisches Centrum GmbH).
