Strength test

thingiverse

This is a initial design for a strength test, it is expected to break at around 40kg using ABS. The specimen should break at the middle section. Print Settings Rafts: No Supports: No Infill: 100 % Notes: Print at full infill in order to obtain high reproduceability (The prints are small and will not require much material anyway) The prints should be done at the optimal temperature for your material, test this first, for example with the heat tower. Print at least five vertically and horizontally in order to get a reasonable sample size. How I Designed This Design objectives The idea of the design do a ultimate tensile strength test of your filament to better understand properties and thus be able to create better designs. The specimen is designed to be able to be printed vertically and horizontally without supports as well as to break on the midpoint. It was also a design objective to create a specimen that would break under a reasonably low force so the experiments are reproduceable at home. Changelog Changes made to the design will be posted here, it is intended to be frozen soon so testing can be started. Edit 1: Attachment holes has been shrunk to avoid stress concentrations.
