Print3D software, a free plug-in, works with Pro/Engineer, SolidWorks, and Inventor to provide real-time feedback and quotes for custom manufactured parts directly in the CAD program. The software makes it unnecessary to export .STL files or upload files to external Web sites. Non-CAD users can also benefit by downloading the standalone plug-in.
