Simple Connector Lab - Bearing/Compression Failure Test
Description
Simple Connector Lab This Simple Connector Was Designed By Students At Sdsu For An Experiment. The Connector Is Designed To Break At A Specific Compressive Force To Obtain The Ultimate Bearing/Compressive Strength Of The 3D Printed Material. From Our Testing We Found The Average Ultimate Bearing/Compressive Strength Of 3D Printed Pla To Be 34.3 Mpa (5000 Psi). To Calculate The Ultimate Bearing/Compressive Strength Of The Material The Follow Equation Can Be Used: B = P / A Where: P = The Load At Which The Specimen Broke -The Connector Is Designed To Break Between 2.8 Kgs To 3.0 Kgs Or 6.2 To 6.6 Lbs A = Area Of Failure Surface = (Thickness Of Layer Below Block)*(Perimeter) -The Failure Surface For The Bearing/Compressive Connector Is The Area At The Bottom Of The Small Peg – The Dimensions Are Designed To Be 2 Mm X 0.4 Mm; However, You Should Measure The Dimensions With A Caliper To Check These Values. This Lab Is Designed To Give Students Experience With Basic Engineering Design And Provide Students With The Mechanical Properties Of 3D Printed Material, Which Can Be Used In Design For Later Labs. More Information On This Lab And Other Labs Will Be Available Soon In The Form Of A Lab Manual From South Dakota State University.
