Overview
The purpose of this project is to determine mechanical properties of polymer components printed with the open source RepRap Mendel 3-D printer. Standard test methods are to be used to gather accurate and acceptable test data. The results of the mechanical testing will be used for engineering analysis of parts designed to be created with the RepRap.
Testing Standards
ASTM D638-10 Standard Test Method for Tensile Properties of Plastics
Test Specimen
ASTM Type I specimen - STL file revised with starting point outside of specimen STL file
Printer settings to test
All g-code will be generated using Slic3r software from http://slic3r.org/
