Reversed Engineered and Remixed Parametric Model of "FDM Test Model - Evaluation of multiple effects" by frank_2288 that is licensed under the Creative Commons - Attribution - Non-Commercial license. []


This package contains a parametric model of a Calibration Tool for Material Extrusion 3D printers. The parametric model also contains a python scripted Macro for test parameter re-labelling purposes. The model can be used to analyze the quality of the printer in terms of i.a. overhangs, support structures, feature tolerances and surface roughness.

Please check the attachment for the following files:

-An open source parametric model of FreeCAD [.FCstd]
-STL Model [.stl]

Materials and methods

You may print the model using the attached STL file using any ISO/ASTM Standard Material Extrusion (FDM; FFF) 3D Printer(s).

For accessing the parametric model, use the following instructions:

1- Open the FreeCAD [.FCstd] file using open source FreeCad Software
2- Enter the Test Parameters in the provided Spreadsheet (Regeneration may take a while depending on your hardware specs.)*
3- Press the "Label Refresh" Button in the Part Workbench to Activate the Python Scripted Macro for automatic re-labelling of the test parameters.

*Make sure that entered dimensional test parameters don't overlap each other (Check 3D space) otherwise, boolean operations will be restricted. Increase the dimensions between the features and/or the part base(s) to overcome this constraint.

Wow! really creative approach. Calibration model can be particularly useful for those involved in the development of low-cost 3D printers. Cheers!
