Many applications require materials whose response can be tuned such as morphing wings for supermaneuverable vehicles, soft robotics and space structures. Nature achieves this objective using external dermal features – skin, furs, tooth, feathers. These nonlinearities are generated using the geometry and topology of the scales The scales provide distinct structural advantages such as protection and tailorable response from scales contact Scales also aid in highly dynamic life functions – such as locomotion, anti-fouling, flapping flights, swimming. Material to structural correlations are highly nonlinear due to scale topology. We aim to reveal structure-property-architecture correlations for automated 3D printed designs.

Anisotropy Evolution Due To Surface Treatment On 3d-Printed Fused Deposition Modeling (Fdm) Of Acrylonitrile Butadiene Styrene (Abs), Blake E. Lozinski

Honors Undergraduate Theses

Purpose: This paper will present insight to the methodology and results of the experimental characterization of Acrylonitrile Butadiene Styrene (ABS) using Fused Deposition Modeling (FDM). The work in this research explored the effects of print orientation, surface treatment, and ultraviolet (UV) light degradation with the utilization of Digital Image Correlation (DIC) on ABS tensile specimens.

Design/methodology: ABS specimens were printed at three build orientations (flat (0 degrees), 45 degrees, and up-right (90 degrees)). Each of these specimens were treated with three different surface treatments including a control (acrylic paint, Cyanoacrylate, and Diglycidyl Bisphenol A) followed by exposure to UV light …
