Melt electrowriting (MEW) is an electrohydrodynamics (EHD)-based additive manufacturing paradigm for printing microscale fibers. Although models charge transport during EHD have been described, significant challenges arise from the in-process dynamics in MEW process, which limits achievable print resolution. This paper advances a methodology to analyze effects of on MEW-printed structure First, fibers printed with oscillating toolpath exhibit two distinct alignment patterns constituent...
Melt electrowriting (MEW) is an emergent approach to fabricate 3D porous structured materials or scaffolds with microscale architectures. Due its facile implementation, solvent-free process, and high tunability, functionalized MEW-enabled are widely used mimic the extracellular matrix, thereby providing a provisional structure for tissue culture. This review firstly describes state-of-art material design strategies that leverage unique versatility of MEW attribute tailored fiber diameter,...
The sequence current-based fault phase selector and traditional low-voltage have difficulties in being applied to the weak-infeed side. This study proposes a new method of ground selection for high-voltage/extra-high-voltage transmission-line protection under conditions. utilizes relative phase-angle relationship between negative- zero-sequence voltages superimposed positive-sequence voltage negative-sequence identify Theory analysis simulation proven that proposed has high immunity against...
Abstract Melt electrowriting (MEW) is an emerging additive process for high‐fidelity, microscale fibrous scaffold fabrication. However, achieving precise multilayered MEW‐enabled scaffolds limited by the entrapped residual charges owing to charge‐based mechanisms. Specifically, semi‐conductive nature of processed materials causes retainment net positive and jet–fiber repulsion, while exposure electric field yields charge polarization with resultant attraction. These competing effects work in...

A key challenge needs to be addressed using a microfluidic-based printhead (MBP) increasing controllability over properties fabricated microtissue. Herein, MBP platform numerically simulated for solid and hollow microfibers microfluidic channel system with high level microfiber geometrical...
Abstract The printing accuracy of the melt electrowriting (MEW) process is adversely affected by residual charge entrapped within printed fibers. To mitigate this effect, amount ( Q r ) must first be accurately determined. In study, measured a commercial electrometer at nanocoulomb scale for MEW‐enabled scaffolds. Based on enabling measurement, effects various design parameters (including substrate surface conductivity σ , time t layer number N ), and voltage U translational stage speed v...
Abstract Melt electrospinning writing (MEW) that processes molten polymers has emerged as a reliable method to fabricate high‐fidelity fibrous tissue scaffolds for investigation of cell biological performance function structural features. However, most the current investigations have focused on with homogeneous features, which can yield outcomes expected. In contrast, spatially heterogeneous well‐defined, non‐uniform pore attributes serve biomimetic, multiplexed platforms investigations....
Recently, China has started paying more attention to environmental protection, and the efficient utilization of exhaust gases produced by smelting emerged as a key problem concern. The silica fume collected from ferrosilicon or industrial silicon was often used cement concrete admixture. Using an asphalt modifier can make profitable. In this study, fume/SBS composite‐modified mortar prepared improve performance asphalt. effects content, temperature, ratio filler on were studied through cone...
Melt electrohydrodynamic processes, in conjunction with a moveable collector, have promising engineered tissue applications.

This study presents the development and characterization of a low-cost bioprinting system with compact low-profile quad-extrusion head for producing multi-material tissue constructs. The system, created by modifying an off-the-shelf three-dimensional (3D) printer, enables larger print volumes compared to extant systems. Incorporating gelatin methacrylate (GelMA) as bioink model, was systematically tested two different printing techniques, namely traditional in-air (IAP) mode along emerging...
