- Bending tests on printed specimens with different infill and print directions.
- Those measured properties go into an Abaqus model of the arm.
- The model is checked against a loaded real arm, for deflection and for the first bending mode.
Project Volans / Test and analysis / #11
Printed PETG: FEM vs test
Measure how stiff and strong printed PETG really is, then validate a FEM model of the Faust arm against a real bending test.

The project
02 / Why
What it gives Volans
Faust, the Base and the guards are all printed. This gives every one of those parts real material data instead of a datasheet guess.

Success looks like
- Measured stiffness for each print setting
- FEM deflection matches the test arm
Planned project. This page will be updated with results once the work is done.
