I had heard that resin prints were more isotropic than traditional FDM prints so tested it on my school's loadframe. The ultimate goal is that I could run FEA on resin parts which is not possible on traditional FDM printing.

Samples were a modified version of the ASTM plastic standard test bar.

All data came as CSVs so wrote a quick matlab script to normalize and calibrate the data then generated some plots in Excel. The whole file is here and all graphs are inserted.

The sudden jump in some plots is when an averaged run turns into a single sample run due to all but one sample failing.

Mostly, this was run with 3 samples per scenario with cure time, temperature, build orientation, and notches changed. This was not extremely scientific but shows good promise that resin is isotropic or can be treated as nearly isotropic.  All plots are in KSI
