MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
This a fantastic little product, I am getting my graphics students to sketch and slightly alter the design to suit their requirements and then 3D print. Would you possibly have the model files (Inventor or Fusion files) before they were converted to STL. It is possible to save the stl as an ipt but it is difficult to edit afterwards.
