Profile: Central One,Inc. specializes in providing different types of prototypes. 3D printing is ideal for rapid prototyping due to low cost, fast development time, and material selection. 3D CAD files can be loaded and transformed into a part in less than 24 hours from start to finish. These factors make it easy to get a part in hand to test form, fit, and function. 3D printing often offers the lowest cost for prototypes. The major reason why 3D printing is so cost effective is no tooling is required. A 3D printing machine can be programed to print a wide range of parts without the need for tools or fixtures.
