Title: Thickness and Load-Deflection of Direct Ink Write (DIW) Polymer Parts

Abstract

Parts were made by direct ink write (DIW)using a developmental 50 A durometer ink. Thickness and load-deflection were measured at four test locations on each part.Original thickness was measured using a digital thickness gauge (Checkline MTG-DX) with a 28.7-mm-diameter foot applying 0.6 kPa stress. Load-deflection was measured using an Instron 5966 equipped with a 10 kN load cell, 28.68-mm-diameter fixed lower platen, and a 50-mm-diameter spherical seat upper platen. Three load-unload cycles to a compressed thickness of 0.85 mm were performed at a test speed of 1.26 mm/min. The compressed thickness was corrected to account for instrument compliance. Original thickness is given in Table 1. Load-deflection curves(engineering stress vs. compressed thickness)are shown in Figure1. Load-deflection data(uncorrected thickness, compliance-corrected thickness, load, and engineering stress) is provided in Tables 2-4.
