This directory contains all relevant files and data for conducting and analyzing the forces acting on the hotend during printing. 

Contents

    1. Slicer Project Files

        -The project files are provided in .3mf format and were created using SuperSlicer version 2.5.59.

        -Each .3mf file contains the full print settings and geometries (stl) of the corresponding test specimens.

    2. Measurement Data

        -For each .3mf file, there are 3 corresponding .h5 (HDF5) files containing the recorded force curves of the printed test specimens.

        -Another HDF5 file also include the segment boundaries (e.g., layer ranges, infill, perimeters, etc.), allowing for segment-wise analysis.

	-The sequence of the various test bodies is as follows: Extrusion Multiplier (1-3), Nozzle Temperature (1-3), Printing Speed (1-3), 
	 Line Width (1-3) and Layer Height (1-3)

    3. Data Acquisition Code

        -The code used to collect force data during the printing process is included.

        -The scripts document the interfaces and methods used to record the force curves in sync with the printing process.

Notes

    -The .3mf files can be opened directly in SuperSlicer 2.5.59. Reproducibility is only guaranteed with this or a compatible version.

    -The .h5 files can be accessed using a wirde variety of programs 

    -Running the data acquisition code requires an Arduino, which reads out the load cell and transmits the signals.
