“What is the link between SIMPL / DREAM3.D and SGLB?”

Jeff take a look at the Oct 2017 slides.

Data Fusion and Mining of In Situ Monitoring Sensors, Process Modeling, and Defect Characterization in Powder Bed Fusion Additive Manufacturing

Slide 2 lists Mark Cola as a contributor.

Slide 12 - "Multi-Modal Registration & Fusion"

This slide breaks down the desired data into 3 categories: CAD, Process intend & Monitoring, and CT, which represent the three phases of the build.

Slide 26 – “Transitioning to Industry Programs”

“Automated Registration of Intent, In-situ, & Post Build Characterization Data”

This slide graphically illustrates the combination of the three data categories of the three build phases from Slide 12 into the “Registration Data”:

"CAD (.stl) + PrintRite Point Cloud + CT Scan = Registered Data"

To me, DREAM3D was conceived to gather, reduce and then combine the characterization data into a “single” registration file. This file can then be used to either show that the build processes was successful because the combination of the in-situ data and the added post-build CT data did not identify any defects and the completed part conformed to the original CAD file. Or, if defects were identified, then the source of the defects can be identified by looking for deviations in the build process data captured during the build.

“Automatic keypoint extraction, mapping computation, and transformation application for all geometry types, within DREAM.3D ------> Fully automatic, one-click registration”

What this slide clearly shows is that PrintRite is the center piece used in DREAM3D to gather the in-situ characterization data. This industry open-source software does not replace PrintRite3D, but adds additional value to it and can help drive industry adoption of PrintRite.
