Advanced Design, Fabrication, and Applications of 3D-Printable Piezoelectric Nanogenerators

The Piezoelectric nanogenerator, a leading-edge mechanical energy harvesting device used in portable power supply and self-powered sensor systems, is a leading-edge mechanical energy harvesting system used in portable power generation and self-powered sensor systems. PENGs are now available in 3D printed form from Advanced 3D printers. This paper explores the most popular 3D-printed piezoelectric nanogenerators in terms of material selection and functionalization, layout and architecture construction, and applications such as pressure sensors, flow sensors, microphones, and implants. This work is expected to help reduce the gap between 3D printing and PENG technologies and propel the analysis and development of 3DP-PENGs.

Reducing Surface Roughness of 3D Printed Short-Carbon Fiber Reinforced Composites

Following laser surface polishing treatment using a 50 W laser power and a frequency of 50 kHz, a significant decrease in surface roughness of 91. 5 percent was achieved on the S3 Onyx 3D-printed specimen.

Evaluation of stress and deformation in a 3D printed M1911 pistol frame using finite element analysis

In recent years, the firearms manufacturing industry has investigated replacing firearms frames with lightweight materials, such as polymer. This type of advancement in the manufacturing industry can help the users be more efficient and reduce potential injuries. Additive manufacturing manufactures can be used to produce virtually every 3-dimensional object using a two-dimensional layer fabrication process. However, there are no studies that have been published yet on the performance of polymer weapons frames. In addition, supporting studies regarding the ability to withstand the pressure and strain of the blowback and recoil process should also be carried out. Using Finite Element Analysis, this research investigates the stress and deformation of a 3D-printed pistol frame made of polymer to close the chasis. A comparison between steel and polymer frame materials is also investigated to show its results. Polymerization will reduce the weight by 51. 7 percent, according to the analysis findings.
