Additive manufacturing (AM) company ExOne, has produced a fully 3D printed, interlocking designer steel necklaces of its kind for the LACE by Jenny Wu jewelry line.

The necklace was 3D printed in steel using ExOne’s binder jetting technology, an AM process in which a liquid binding agent is selectively deposited to join powder particles.

‘Unlike most 3D printed necklaces out there, our pieces are fully 3D printed without any additional analog assembly nor non-3D printed hardware to hold these incredible statement pieces around the neck,’ said Jenny Wu, director of LACE. ‘This type of necklace was a technical and financial challenge to 3D print entirely in metal until now. While we love the wearability of our nylon necklaces, our goal was always to 3D print our necklaces in metal, from the hinge down to the latch. After many years of testing and prototyping with various different technologies, we were finally able to produce the Catena necklace with ExOne and their 3D printing process.’
