3D Systems announced that KALLISTA unveiled the Grid sink faucet – which was produced by 3rd Dimension using 3D Systems' 3D printing materials and technology. 3D Systems' technologies afforded KALLISTA design without limitations to bring this first of its kind sink faucet to market. KALLISTA's design team embarked on a journey to create a faucet in a unique geometry. In deciding to produce the spout via 3D printing, the designers were able to design without limitations to create an open form and discreet interior channels that allow water to flow easily through the base. The faucets were produced by metal 3D printing specialist, 3rd Dimension, a high quality production metal manufacturer specializing in 3D direct metal printing based in Indianapolis. 3rd Dimension employed 3D Systems' ProX DMP 320 high-performance metal additive manufacturing system. To avoid rust and corrosion, the faucets are printed with 3D Systems' LaserForm 316L, a high quality stainless steel 316 powder material.
