Abstract In polyjet printing photopolymer droplets are deposited on a build tray, leveled off by roller and cured UV light. This technique is attractive to fabricate heterogeneous architectures combining compliant stiff constituents. Considering the layer-by-layer nature, interfaces between different photopolymers can be formed either before or after curing. We analyzed properties of in 3D printed composites experiments with computer simulations. To investigate blending, we characterized...
Abstract Physical aging refers to relaxation of the polymer glassy state toward amorphous and this phenomenon affects their physical‐mechanical properties. This work investigates effect physical on scratch behavior visibility. It was shown that mechanical properties were significantly modified over time, especially yield stress, in turn affecting behavior. As a matter fact, critical load for onset visibility increase with aging, thus improving sensitivity scratches. Such strictly related...
Abstract Polymer scratch mechanics has been widely studied. However, the physics behind visibility is still not well understood. Scratch deformation mechanisms certainly affect but also other material properties, such as roughness, color, or gloss. This work relates to methods quantitatively evaluate effect of sample color on polymer and mar induced visibility, aiming at linking behavior with underlying physics. A custom‐built black box was utilized for analysis samples possessing different...
