Ottobock launches iconiq, the 3D printed silicone liner

Published on June 01, 2026 | Translated from Spanish

Ottobock has launched iconiq, a silicone liner for prosthetics manufactured using 3D printing. This component precisely adapts to the shape of the residual limb, offering a more comfortable and durable user experience for people with amputations. The technology allows each piece to be customized, facilitating access to prosthetics tailored to individual needs.

Additive manufacturing for a precise fit 🖨️

The 3D printing process allows for the creation of an internal structure that distributes pressure more evenly over the residual limb. Unlike traditional liners, manufactured with standard molds, iconiq is designed from a digital scan of the user. This reduces friction points and the need for subsequent adjustments. The silicone used offers wear resistance and maintains its properties with daily use.

Goodbye to socks for filling 🧦

Anyone who has used a prosthetic knows that the perfect fit is a myth. Before, to prevent the residual limb from moving inside the socket, you had to stuff wool socks in until it was firm. Now, with iconiq, the silicone does the dirty work. Of course, veterans in the field will miss that thing of fitting the residual limb as if it were a Lego foot.
