The best way to improve communication and facilitate better feedback and decision-making from stakeholders is with prototypes.

Early-stage prototyping not only helps you more effectively convey design ideas, but also helps you identify and address potential issues early in the development process, so you’re able to have design validation and iteration.

The STL file format has become recognized as the standard for RP machines. Note that STL files are produced by CAD systems that are based on surface and/or solid modeling only. 2-Dimensional and Wireframe CAD systems do not output STL files.
