Plethora is building the factory of the future. We believe everyone should have access to the powers of creation - the ability to think of an invention and instantly get feedback on its manufacturability and cost, and then get it as quickly as possible. We’ve created a manufacturing system that turns customer designs into custom parts using robotics and advanced software that we’ve developed in-house. Our customers are R&D engineers, product designers, startups, scientists, makers, and artists.
