We recently posted an episode of The Cool Parts Show featuring Günter Kappler and his work to design, 3D print and test metal bellows as an alternative to conventional production methods. In the video, he describes the lessons he learned in developing these parts so that they would not only print reliably through laser powder bed fusion but also provide the needed flexibility outside of the printer.
But bellows aren’t the only potential application for this work. This week, we’re sharing another example of a flexible 3D printed component from Günter: ductile spikes intended for audio speakers. Traditionally, spikes or resonance compensators might be placed under a speaker to either pass its vibrations to the floor or to isolate it from the ground. The 3D printed ductile spikes seen in this bonus episode are different, in part, because they’re meant to do both. Watch more here.
Below: 5 Other Ways to Improve Your Soundscapes with 3D Printing
MasterPrint® Robotic of Ingersoll’s AM equipment family has the ability to seamlessly program, simulate, 3D print and mill large composite parts in a single piece. Register now to book a visit.
Grid Logic’s multimaterial powder bed process uses conventional metal powders, but leaves the melting of these materials until after printing is complete. How does the powder support itself? It doesn’t. Sand serves a temporary support, but because there’s no binder, it is infinitely reusable. Read more here.
Sound control items. X user Mark Rhodes recently used GPT4 and OpenSCAD to design 3D printable wall tiles that use a mix of cube-like structures to reflect sound. While this was a home project, other 3D printing companies like PrintFoam and Desktop Metal have mentioned 3D printed soundproofing panels as possibilities for their printing technologies. And, DiveDesign is actively looking for pilot testers for Willo, its line of sound-absorbing 3D printed trees made from recycled materials!

Hearing aids. What if your hearing needs a bit of a boost in the first place? Smaller in-ear hearing aids and those that make use of 3D printed ear molds (the piece that sits inside the ear) are becoming more accessible, making it possible to receive a custom-fit hearing device without the hassle of having an impression taken of your ear.
5.
Ear plugs. Or, maybe you're after ear protection or just a way to reduce noise in your daily life. 3D printed custom ear plugs are available for a whole range of activities, from swimming to drumming.
