Thanks to Jacki Dee over at the E-Textiles Facebook group I discovered these beautiful necklaces by Nervous System on dezeen. Nervous System may sound familiar because I’ve blogged about their fab Kinematics dresses. Similar to the interlocking pieces found on the dresses, these necklaces come out ready to move and slink gracefully on the neck.

They are 4D printed, which has its own advantages.

“4D printing refers to 3D-printing something in one shape that is intended to be in another shape,” creative director Jessica Rosenkrantz told Dezeen. “The design transforms into its final configuration without manual labour. The shape it is printed in may be advantageous for various reasons: faster, cheaper, or printing larger objects in a smaller volume.”

So, instead of printing individual pieces and later having to attach them together, a necklace prints with triangular shapes folding out of the way to maximize space in the machine. A finished necklace merely unfurls when touched—a beautiful flow of geometry. One of the interesting things about Nervous System is that they have apps so you can design your own work. Check out their Kinematics app if you would like to try your hand at morphing their necklace template into your own creation. Also, don’t forget we’ve got our share of 3D projects, including this glowing LED Bracelet. 3D printing opens the door to custom jewelry and smart solutions for wearable tech.
