Stratasys (Eden Prairie, Minn., U.S.) has launched an Advanced FDM feature for its GrabCAD Print 3D printing software. The feature has been designed to eliminate CAD-to-STL file conversion, simplifying the overall process and resulting in quicker delivery of lightweight, strong and purpose-built parts. By avoiding CAD-to-STL conversion, users are reportedly able to work in high fidelity to quickly advance the design-to-3D print process without losing design intent, boosting both time to market and time to revenue.

The software automatically calculates 3D print tool paths after engineers select areas on native design geometry and specify design attributes directly to CAD models. No manual generation of complex tool paths is required. Users pinpoint areas of strength and rigidity, control infills, ensure sufficient material around holes with inserts and avoid seams. Since tool paths are automatically generated from model assignments, the user spends less time on part setup. 

According to the company, the software also streamlines part processing by eliminating the use of multiple programs, helping to control the structure of end-use parts for markets such as automotive.

Advanced FDM is available for download with GrabCAD Print (versions 1.24 and later) and is supported on a variety of Stratasys 3D printing systems: F370, Fortus 380mc, Fortus 380mc Carbon Fiber Edition, Fortus 450mc, Fortus 400mc, Fortus 900mc and F900.
