Effect of Infill Density and Infill Pattern on Mechanical Properties of 3D-printed PLA Produced by FFF

Fırat Üniversitesi Mühendislik Bilimleri Dergisi
With the rapid advancements in Additive Manufacturing (AM) technology, examining the mechanical properties of products utilized in this process has become increasingly important. The mechanical properties of 3D-printed products are significantly influenced by the choice of printing methods and printing parameters.

Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor

Advanced Materials Technologies, EarlyView.
We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into

Zoning’s Centennial: A Complete Account of the Evolution of Zoning into a Robust System of Land Use Law—1916-2016 (Part IV) [PDF]

, 2016
Fracking is happening and local governments are subjected to many of its associated risks. They either need to act, or know—clearly and convincingly—why they should not. The federal government has stopped far short of comprehensive regulation of fracking;

Electron beam absorption in 3D-printed polymer samples with different infill densities

Journal of Physics: Conference Series, 2019
Abstract In this work, we study the efficiency of electron absorption by the plastic samples produced using 3D printing with different infill densities. We investigate the influence of the print layer orientation relative to the electron beam axis on the radiation dose distribution.

3D Printed PEDOT:PSS‐Based Lattice Pressure Sensors With Tunable Electromechanical Response

Advanced Materials Technologies, EarlyView.
poly(3,4‐ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS)‐based architected lattices are fabricated via single‐step Digital Light Processing (DLP) printing for tunable pressure sensing. Structural design variations allow precise control of sensitivity and range, while integrated conductivity eliminates post‐processing.
