tension rod
thingiverse
It's a precision rod designed specifically for evaluating polymeric material characteristics. Its dimensions match those typically used in polymer testing. Since there is no established standard for testing 3D-printed components, I use this STL file to create all my test rods with 20 top layers (100% infill - not 100% infill setting). Additionally, I employ the optimal printer settings for achieving the best results on my test geometry, as showcased in my other creations. I operate at a print speed of 30 mm/s and layer height of 0.2 mm. When testing material properties, it's crucial to print a minimum of three tension rods for statistical reliability.
With this file you will be able to print tension rod with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on tension rod.
