Description

Yes, this is a 3D model of a rectangle.I am writing a blog series about designing a low cost yet very capable homemade testing machine and using it to analyze the mechanical properties of 3D printed materials.This rectangle is actually a test specimen specifically designed for a 4 point bend loading on my machine. .You can follow along with the project at the link below, any feedback or fresh ideas will be greatly appreciated! What mechanical properties would you test  http://engineerdog.com/2015/03/24/introduction-to-3d-printing-materials-testing-series/

<p>Hi EngineerDog!<br><br></p><p>That's a great initiative. I'm personally interested in trying to evaluate the resistance to delamination (adhesion between layers is probably the weakest parts of any 3D printed part in FDM). I can also provide you some papers that I've been gathering (you're not alone, but I agree that research doesn't seem much available to public. Some big business issues here maybe...). If you're interested send me an email at mmemetea (a) gmail.com:</p><p>Some of the interesting papers title:<br>* Mechanical Properties of Components Fabricated with Open-Source 3-D Printers Under Realistic Environmental Conditions<br>* Advanced Modelling and Infilling Algorithms for 3D Printing</p><div><div><div><p>&nbsp;* Build-to-Last: Strength to Weight 3D Printed Objects</p><p>* Chopper: Partitioning Models into 3D-Printable Parts</p> <div> <div> <div> <p>&nbsp;* Stress Relief: Improving Structural Strength of 3D Printable Objects<br></p> <div> <div> <div> <p>&nbsp;* Clever Support: Efficient Support Structure Generation for Digital Fabrication (This one seems to have made into meshmixer!)<br>Cheers,</p><p><br></p><p>Michaël.<br><br></p> </div> </div> </div> </div> </div> </div> </div> </div> </div>
