Pennsylvania-based Verde Mantis, LP designs and builds the Mantis desktop 3D Printer in the United States, along with upgrades and engineering services. Founded by Joe Sinclair, the company built its flagship machine around a two-step, file-to-print experience, with onboard software and sensors handling much of the setup that traditionally challenges new users. Its small team also applies the engineering and manufacturing experience behind the printer to customer product-development and prototyping work.
