Example 23: Automatic Calibration of PRM Files

Problem Description

Sample files for use with the examples are available in the Local_Simulation_example_Files_2021.1.zip package from this Download Link. Expand the downloaded ZIP archive into a convenient directory from which you can run Local Simulation inside the numbered directories.

This example guides users through the process of automatically calibrating a PRM file based upon an experimental print and an existing PRM file. Cases where this may be useful:

• To further increase the accuracy of a generic or custom PRM file
• Generating PRMs based upon generic PRM files using differing process parameters
• To generate a PRM for a similar but not yet included material set based upon an existing material.

Cases where PRM Calibration will not be useful:

• Generating a material for a dissimilar material set from any of the established PRM files, such as MS1, Copper, Polymers
• Generating PRMs for non-supported processes like FDM or DED
• Generating PRMs for differing hatch patterns, particularly non-supported options like unidirectional or bidirectional scanning.

For this tutorial we will focus on the primary use case, to increase the accuracy of the generic Inconel 625 PRM file based upon an assumed experimental measurement.
