Limited Capacity seats available

The Purdue Polytechnic Precision Measurement Lab 3D printed test coupons for impact tests, tensile tests, and torsion tests using various 3D printing filament materials. The materials tested included ABS, PLA, Bronze filled PLA, Carbon Fiber filled XT, Co-Polyester nGen, Polysmooth, and a Hemp based filament. Multiple samples of each material were then tested to determine the various strength attributes of the materials for comparison. Two batches of test coupons were tested for the Polysmooth material. One batch was tested directly after printing and the second batch was tested after it had been smoothed in a Polysher (an isopropyl mist chamber for smoothing the surface of Polysmooth printed parts).
This presentation will share the results of the testing and images of the tested parts which taken with a digital camera equipped microscope.

Conflict of Interest Statement
Dr. Padfield is not affiliated in any way with of the manufacturers of the materials tested. All material and equipment (the Polysher machine) was purchased online at the full advertised price.
