SOLIDWORKS 3D CAD Matrix

3MF

If you have Microsoft® Windows® 8.1, you can print directly using the 3MF format included. Simply set the print options in the 3D Print PropertyManager and print to the 3D printer. A preview of the print bed and the model's location within the print bed lets you modify settings before committing to a 3D print job.

To access the 3D print dialog box and specify print options, click File > 3DPrint.  The print dialog box that is available depends on your installed 3D print driver.

AMF

You can also export part and assembly files using the Additive Manufacturing File Format (AMF), an XML-based format designed to support additive manufacturing processes like 3D printing. In addition to the model geometry, an AMF file can contain information about the color and materials of objects for 3D printing.
