3D printing will mention what you think? Black science and technology, high force grid, Geek range of children? But what is certain is that, for those people who groundbreaking, 3D printing means to make themselves become magical brush Ma Liang. Doctors can use 3D printing to make high-precision dentures, and even human organs, heal the sick, and his continued life; engineers can use to design a variety of 3D printing has never been achieved before structural innovation, thus promoting the industrial revolution; 3D artists can use printing takes us from abstract paintings to the two-dimensional plane in a more magical and three-dimensional three-dimensional visual space.

Since 3D printing technology is so advanced, so when 3D printing meets HiFi headphones, what will spark clashes it? Today we’ll take stock of what those uses 3D printing technology black earplugs and brand.

First, the most expensive –Final Audio LAB series earplugs

噱头、逼格、技术兼备——细数那些3D打印技术的黑科技耳塞

Final Audio from Japan is a “small minority” HiFi brand, although a small minority, but in the name HiFi circles Final Audio can be said that no wonder known to everybody. Mr. Jinsheng Takai Final Audio brand was founded in 1974. With accumulated from sound design and technical strength, as well as unique among Yifan unique tuning style, Final Audio of each product almost become the object of fans mouth hot. Example, using “Balancing Air Movement” (BAM) air flow technology iron ear FI-BA-SS, and the like appearance “chamber pot” Piano Forte series of moving coil ear.

As a unique and pursuit of technological innovation company, Final Audio 3D print this nature will not ignore the existence of black science and technology. LAB series earplugs earplugs series is Final Audio uses 3D printing technology design and manufacturing, but also Final Audio’s most expensive earplugs series. Currently there are LAB1 LAB series earplugs and LAB2 two, positioning are the flagship.

Unlike common 3D printed article using non-metallic materials such as resin, Final Audio uses a hard and precious metal 64 as a starting material titanium Lab 1 in design and manufacture, a series of complicated processes, the profile 64 is made of titanium beat unique headphones, both to ensure Lab1 optimal acoustic design, while retaining the Final Audio brand has always been noble and delicate texture of the ice.

After the world’s limited 150 and the price of up to 12800RMB Lab1 success, Final Audio under the new president has introduced a fine tail-led follow-up model of LAB2 LAB1 earplugs. And before the difference is, LAB2 LAB1 completely abandoned before the appearance of smooth design and the movable iron structure in favor of a more dynamic structure and the bold print full 3D hollow design. At the same time the price is more expensive, reaching 24999RMB. It is said that people have heard linger, indulge them. Not bad money tyrant may wish to try Oh.

Second, most comfortable –Snugs custom ear mold

噱头、逼格、技术兼备——细数那些3D打印技术的黑科技耳塞

Ear Earphones mention what would you think? Most people think of first is a good sound insulation, but can not wear a long time, there is no flat head ear plugs so comfortable. Indeed, long time to wear earplugs ear discomfort there is an indisputable fact.

Exclude individual ear canal sensitivity of the issue, usually the ear headphones will produce the main reason for people to wear ear discomfort due to irregular shape and can not exactly match the sleeves. So in theory, if the ear portion of the headphones is based entirely human ear canal shape custom, then there will be no problem to wear uncomfortable. But is not the case, there are still a lot of custom headset users to customize their reaction still comfortable enough to wear headphones, the problem is in it?

Although the custom headphone mixer, crossover technology is developing rapidly, but its production process and technology and not much revolutionary change, or has been in use during the traditional process of making hearing aids. I.e., injection printing paste, ear ear samples, cured and then polished according to the ears by hand printing, imprinting, injection molding resin is cured, and finally become making custom earplugs.

Snugs companies from the UK to the existence of the first to recognize the problem, and indicate the cause of customized headset uncomfortable lies in this custom-made headphones processes. The main problem from two aspects, one is custom-made ear headphones Indian sampling is not precise enough lead to make the last out of the custom ear headphones can not be a perfect match; the second is a custom headset itself is made of a hard material, soft enough to not be as soft the shape of the human ear canal changes.

To this end, Snugs company gives their own solutions, a 3D model of the human ear headphones customized data sampling plus soft film with high precision 3D printing. Ear new 3D modeling data using digital sampling techniques 3D modeling, to generate highly accurate 3D modeling data in accordance with the shape of each person’s ear canal by professionals, to avoid the traditional ear printing paste and easily roughened sample deformation problems.

While high precision 3D custom printed flexible film, but also avoids the situation where the conventional manual made for molding produced unstable, greatly reduces the problem of quadratic error custom ear mold manufacturing process. Meanwhile deformability of soft medical silicone membrane material is far superior to hard resin material, not only can adapt to the ear canal deformation due to chewing, talking and other facial movements caused, while a soft skin-friendly texture can be further enhanced wearing comfort . HiFi in well-known foreign media AudioHead experienced Snugs after the custom ear mold, but also gives a high evaluation of comfort out of 10 points, showing that the headset Snugs in terms of comfort study design attainments.

Third, the most professional –Ultimate Ears custom earplugs series

Ultimate Ears, a custom headset industry can not bypass the legendary brand. As a custom headset pedigree and manufacturers of traditional technology, Ultimate Ears after the acquisition by Logitech and not satisfied with past achievements, pioneering and innovative use of existing resources to more advanced technology into new products.

Ultimate Ears UE18 + Pro in the development of new products such as discovery, there are many important details had been overlooked in the design and manufacture of custom headphones process. Such as how the wearing comfort of the problem by printing a reasonable ear mold repair and improve customer production; how to customize through scientific acoustic design headset earphone housing units and custom integration issues and so a perfect match.

In order to solve these problems at the source, Ultimate Ears to hire a professional technical personnel, and set up a new professional laboratory, use pure hand to replace the previous 3D scanning and 3D printing custom repair mold making process, not only greatly enhance the custom headphones production efficiency, more effectively enhance the accuracy of production of each pair of customized headphones, avoid product accuracy problems because of the production process caused by human factors.

Meanwhile, in order to better play the acoustic characteristics of each one iron unit, Ultimate Ears also use 3D printing technology designed specifically for each of the acoustic structure of an integrated iron unit, because both to avoid division, cell placement generated the phase problem, but also to avoid the custom headphone cavity caused by different shapes and sound quality is not uniform issue.
