I want to tackle an experiment with the following goal:
Determine the correlations between printing parameters (temperatures, speeds, humidity, perimeters, infill, etc.) and tensile strength using a specific 3D printer, test specimen, and filament brand/model.
This goal calls for two parts then: a standardized test procedure and test specimen. For the test procedure, I've been asking myself:
What portable, measurable and roughly consistent tensile strength test does not require building a complicated machine, can be performed with ready-made tools or machines available at a large hardware store, and can be set up within 5 minutes?
Is the ISO 3167 multipurpose test specimen an appropriate specimen for the test procedure outlined above or are there other specimens that are more suitable?
I was thinking that, since the usual filaments have an ultimate strength of around 40-60 MPa, perhaps the "recoil" would be too much and one needs to use a smaller, weaker specimen.
