Sennheiser’s Steel 3D Printed Earbuds: Will 3D Printing Lastly Win Over the Headphone Market? – 3DPrint.com

Main headphone model Sennheiser has introduced that its newest earbuds, the IE 600, are to be made with 3D printing. This isn’t solely shocking, provided that Sennheiser’s client division is owned by Sonova, a massive listening to support firm that is likely one of the largest customers of 3D printing worldwide. What’s a shock is that the fabric from which the headphones are made is an amorphous metallic, additionally referred to as bulk metallic glasses.

I’m an enormous Sennheiser fan and personal bulkmetallicglasses.com, so that is fully wild to me. It’s like I’m being focused as a demographic of 1. Bulk metallic glasses are new, high-tech supplies which are very sturdy and extremely abrasion-resistant. For instance, they’ve been used to make gears that can by no means require lubricant. Right here now we have a wonderful interview explaining how bulk metallic glasses have helped NASA´s JPL.

Two startups, Amporphology within the U.S. and Exmet in Sweden, presently 3D print bulk metallic glasses. I haven’t been capable of finding out whose massive win that is, however it’s positively a win for 3D printing. That is additionally massive information for German tech group Hereaus. It’s that agency’s bulk metallic glass supplies which are getting used for the headphones.

Sennheiser claims that the headphones provide ¨direct, impartial tuning with quick, correct bass.” It additional notes:

¨IE 600 has triple the hardness and flexural energy of high-performance metal. Shock-frozen throughout manufacturing, amorphous metals by no means have an opportunity to kind a crystalline construction like typical metals. The result’s a lustrous, satiny floor that’s extraordinary resistant towards corrosion and scratches. The IE 600 housing is fabricated utilizing metal-powder-based 3D printing that may create any form possible inside tight tolerances. Chambers and channels kind as a part of this additive manufacturing course of with no milling required. Nevertheless, value does restrict the potential functions of this new materials. One of many solely locations you’ll discover it — in addition to ultra-high-end merchandise just like the IE 600 — is within the drilling head of a NASA Mars Rover the place extraordinary resilience in excessive situations is required.¨

This may very well be a doubtlessly massive transfer for a phase that 3D printing has to this point did not penetrate. An enormous participant within the in-the-ear (ITE) listening to support market, Sonova makes use of ETEC (née EnvisionTEC) techniques, together with another manufacturers, to 3D print listening to support shells by way of digital gentle processing (DLP) expertise.

Certainly, 3D printing has revolutionized the ITE phase in listening to aids. Customers get a customized listening to support shell that’s extra comfy. Phonak could make these extra cheaply than with different processes. And the retailer depends on a digital course of that enables them to upsell a easy listening to support and switch it into one thing higher for purchasers. It’s a terrific 3D printing success story that has upended this market and made us the default expertise in customized listening to aids.

Whereas we rule that class, now we have not but made a lot headway in client headphones. Even with individuals sporting headphones many hours a day for work, music, and Netflix, our penetration in client headphones has been virtually non-existent. One Phonak headphone tried to blaze the way in which years in the past with 3D printing and the opposite additionally has some consumer-facing prospects in listening to safety for staff, however there’s little else.

There was Regular, a startup that didn’t final lengthy. We’ve additionally seen firms like Final Ears use 3D printing manufacture high-end, in-ear screens for audio technicians and recording artists. Nevertheless, all in all, it’s area of interest. We’re speaking about 100,000 3D printed screens within the case of Final Ears, not the thousands and thousands that Phonak does for listening to aids.

Listening to aids and earbuds use the identical 3D printing applied sciences and the identical processes to understand an element. Typically, a scan of a wax impression of 1’s ear is digitized and repaired. An worker orients it and locations the electronics just about within the 3D scan. That is then despatched to an EnvisionTEC Perfactory, a 3D Programs stereolithography machine, or possibly an ASIGA system, after which printed. Helps are eliminated by hand and the worker works desk facet with the printer to file, flash, wash and assemble the listening to support.

This can be moderately extra artisan than you thought, maybe, however, on the identical time, tens of thousands and thousands of cost-effective listening to aids have been made this fashion. In the meantime, in headphones, individuals casually purchase non-functioning Beats standing symbols for a whole lot of {dollars}. Audiophiles might spend 1000’s on headphones, as effectively. With individuals sporting them for work and play, together with sports activities, many people now personal a number of headphones, extra of them prone to be premium these days.

Nevertheless, the headphone market has been a killing area with new entrants, fickle client conduct, and large gamers making it a supremely aggressive area to be in. That is what prompted Sennheiser´s exit from the buyer area within the first place (Sennheiser nonetheless exists, making glorious microphones and different options for professionals).

I’m salivating. We’ve but to see if it is a cool one-off design that’s meant to titillate audiophiles or if we will likely be seeing extra of 3D printed headphones constituted of bulk metallic glasses sooner or later. I’m significantly pondering of getting them, however at a value of over $600, I’m unsure what number of others will promote. To me, a course of whereby 3D printed, customized polymer headphones will give us all excessive consolation. That may be a surefire strategy to the way forward for 3D printed headphones. Let’s see if that is within the offing sooner or later!
