Over the last few years, the number of 3D printed medical innovations are growing explosively, helping people who believed that they couldn’t be helped and vastly improving the success rate of countless surgeries. However, the most unusual medical tool we’ve seen in a long time must surely be the Absorblight, a lamp developed by Antwerp, Belgium-based designer Bruno Vereecke. Instead of helping people with bad eyesight, as you might expect, this unusual lamp is actually intended for the partially deaf and hard-of-hearing people. A 3D printed hearing aid, so to speak.
