Kohler Case study

Better Technology Leads to Greater Innovation

Founded in 1873, Kohler Co. is a global leader in the manufacture of kitchen and bath products that continually set new standards in design, craftsmanship, and innovation. Numi, its flagship intelligent toilet, allows detailed user customization, with ambient lighting, Bluetooth capability, and a heated seat. The newest model, Numi 2.0, delivers voice activation with a built-in Amazon Alexa, personalized cleansing functionality, and exceptional water efficiency.

However, these features require extremely complex interior designs, and because there are dozens of embedded sensors and over 600 components, a tiny design change could mean a project overhaul. Before the smartest toilet in the world can be introduced to the market, it requires numerous design iterations to ensure quality and functionality. In an effort to expedite the prototyping process, Kohler turned to 3D printing.


 “It is great to have something concrete in hand, so that you can perform different functional tests that are compliant to industry standard.”
