The Company utilizes injection molding, computer numerical control (CNC) machining, 3D printing and sheet metal fabrication to manufacture custom parts for its customers. The Company's customers conduct nearly all their business over the internet. The Company targets its products to the millions of product developers and engineers who use three-dimensional computer-aided design (3D CAD) software to design products across a diverse range of end-markets, to the procurement and supply chain professionals seeking to easily and efficiently source custom parts on-demand, and to a wide variety of customers seeking to purchase low-volume custom parts.
