Simple Connector Lab
This simple connector was designed by students at SDSU for an experiment. The connector is designed to break at a specific tensile load to obtain the ultimate tensile strength of the 3D printed material. From our testing we found the average ultimate tensile strength of 3D printed PLA to be 58.9 MPa (8500 psi).
To calculate the ultimate tensile strength of the material the follow equation can be used:
T = P / A
Where:
P = the load at which the specimen broke
-The connector is designed to break between 2.4 kgs to 2.5 kgs or 5.3 to 5.5 lbs
A = area of the failure surface = (length)*(width)
-The failure surface for the tensile connector is the cross-section of the narrow neck of the connector – The dimensions are designed to be 0.4 mm x 1 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.
