Description
Revised from ASTM Tensile Test Specimen @ thingiverse.com/thing:13694
The change for this specimen is an added cylinder on one corner to create a starting/end point for the layers. This tensile specimen is for a current research project & is associated with benefits for anyone who wishes to collaborate by contributing sets of 10 of tensile specimen.
This a specimen for tensile testing in accordance with ASTM D638 "Standard Test Method for Tensile Properties of Plastics". It is a Type 1 specimen to be made from rigid plastic.
Tensile testing of RepRap printed specimens is being performed at the Michigan Tech Open Sustainability Technology Research Group mse.mtu.edu/~pearce/Index.html. Specific information about the testing can be found here appropedia.org/Mechanical_testing_of_polymer_components_made_with_the_RepRap_3-D_printer.

What was the aim in testing these samples? I'm thinking about running up a few batches of various test pieces to see how prints from different machines stack up as far as their physical properties (RepRap vs Ultimaker vs...). Anyone know of some similar testing done by someone else?
Hi -- The aim was to pull out some concrete values for printed strength on RepRap like machines so that engineers could start to do some real engineering on them.
We still have not posted our results because we are doing a controlled and pretty massive study and want to ensure everything is done right. As of now - the values from our RepRaps are coming in stronger than those published in the literature for commercial machines - so we are double checking everything before we make any big claims.
