Manifold models can be created with polygon modeling software, it just takes more steps and experience. By contrast, software that uses polygon modeling can generate walls that have zero thickness that’s fine for creating computer graphics for games and movies but not useful when 3D printing the models. The list also indicates whether the software uses solid modeling, a type of 3D modeling that always generates models that are “manifold” or “water tight.” A manifold model is one in which all walls of the model have some thickness, which is necessary for 3D printing.

This list includes some of the best options and is sorted by price, with the free ones sorted alphabetically. Now, there are many easy-to-use modeling software options available, many of which are free. Years ago, we had to spend lots of money and time to acquire and learn modeling software. Thanks to Wmayer for his help in writing this script.An Overview Of The Best 3D Printing Software ToolsĮvery 3D print begins as a 3D model generated in a modeling program. Thanks to cae2100 for developing the original macro code - also available here. Print ('Calling subprocess: ' + str(stlFiles)+' ') If () and hasattr(obj, 'Shape') and (len(obj.InList) <= 1): # user need to set this directory where slicing software is located SLICERAPP= 'cura' # Put your Slicer program here Macro_3d_Printer_Slicer_Individual_Parts.py import FreeCAD If a specific object is not exported you might have to add the respective type to the doexport array. The SLICERAPP variable can be changed to any slicing software of your choosing.

It will also create several STL files with the same filename as the design file and the part label in the same directory as the design file. It is best used by creating a link to the macro on the toolbar, and when your ready to slice the object, just click it and your objects, as they appear on the screen in FreeCAD will appear on your slicing software's interface, ready to slice. This macro will look for Cura as the default but you can change it to any other slider by changing the SLICERAPP variable in the source code. This code, when run, will export the visible bodies at the top level (bodies deeper in the tree will be ignored) of the currently open design to individual STL files, and open them it in the slicing software that you use.
