You can send your STL files directly to your slicer from Fusion 360. No need for an application or a script. to enable load any model in Fusion 360 then select to Save As STL. A dialog box will pop up where you can usually set resolution and such. In the section that says Output (you may need to open it by clicking on the little triangle next to the name) check the box next to Send to 3D Print Utility. In the drop down list next to the Print Utility selection drop the list down and select Custom. Next to the Application selection you will see an icon that represents a folder. Click on that folder and a regular Windows file selector will appear. Navigate to where you installed your slicing software and highlight the application by right clicking and click on Select. Now back in Fusion 360 when you hit OK it will open the slicer of choice and the model will already be there ready for slicing. This currently works with: Cura 2.x and 3.x Simplify3D 4.x Slic3r Prusa Edition I could not get Matter Control to open the model automatically . MatterControl opens but the model is not loaded.
