Flexible, lightweight, biocompatible and with a new aesthetic oscillating between randomness and intention: The necklace Einzeller is produced with selective laser melting. Einzeller utilizes the strengths of Titanium to produce a kind of snap fastener. The individual elements can be snapped together to achieve the desired length and to form a necklace or bracelet. The weight of the piece is not really noticeable. The material is biocompatible. The vibrant color is not created by pigments but by an iridescent layer, developed through anodizing.
