Plethora
Plethora's Overview
Plethora was an innovative manufacturing company specializing in rapid prototyping and on-demand production parts through CNC machining, sheet metal fabrication, and (to a lesser extent) 3D printing services. They developed a software-driven platform that provided instant quotes and Design for Manufacturability (DFM) feedback, aiming to streamline the process from design to physical part. A key aspect of Plethora's model was its highly automated 'smart factory'. In December 2021, Plethora was acquired by Xometry, a global digital manufacturing marketplace. Plethora's technologies and services have since been integrated into Xometry's broader offerings to enhance its on-demand manufacturing capabilities.
