The first 3D printed earphones are available worldwide with a limited edition of 150 for 160,000 yen.

3D printing technology has vowed to create the myth that "everything can be printed", and now they have taken a new field - earplugs. The world's first 3D printed earbuds, Final audio design LAB 01, jointly developed by NTT Research Institute and Probox, came out. And began to limited sales, only 150 in the world, of which Japan has 30 sales share, the price of 160,000 yen (about RMB 9467 yuan).

Among them, the parts involved in 3D printing are only the cavity shell of the earplug, which is made of 64-titanium material. Of course, it is not smooth in the development process. It is common for the 3D printed mold to be deformed, so the team has continuously improved. The modeling scheme "to correct these errors and improve the yield.

After the shell is printed, the work has not been completed, and the surface must be reworked to form the polished design we see today, while retaining the rough lines left by the 3D printing in the recess.

Final audio design LAB 01 is a two-unit moving iron earplug with two full-range balanced armatures and a Nordic silver-tone metal. Apart from the price factor, Final audio design LAB 01 is really a stunner. I don’t want to make a profit, the purpose is to show the public the broad prospects of 3D printing technology.
