In the paper “Emission Directionality of 3D-Printed Photonic Nanowires,” a Korea Electrotechnology Research Institute (KERI) team demonstrates how nanowires with a diameter of 300 nanometers display directional light emission. This could see them being used for quantum applications and displays.
In the paper “Real-Time Precision in 3D Concrete Printing: Controlling Layer Morphology via Machine Vision and Learning Algorithms,” a Portuguese team look at machine learning and construction 3D printing, trying to Devine and predict layer width, speed and flow.
Magicians Penn & Teller release five puzzles for 3D printing.
