Three-dimensional (3D) bioprinting using biocompatible polymers has emerged as a revolutionary technique in tissue engineering and regenerative medicine. These biopolymers mimic the extracellular matrix (ECM) enhance cellular behavior. The current review presents recent advancements additive manufacturing processes including Stereolithography (SLA), Fused Filament Fabrication (FFF), Selective Laser Sintering (SLS), inkjet printing. It also explores fundamentals of 3D printing properties for bioprinting. By mixing biopolymers, enhancing rheological characteristics, adding bioactive components, further have been made organ transplantation, drug development, engineering. As research progresses, potential to fundamentally transform healthcare system is becoming obvious clear. However, therapeutic printed structures hindered by issues such material anisotropy, poor mechanical properties, need more biodegradable architectures. Future should concentrate on optimizing process sophisticated computational techniques, systematically examining characteristics customizing bioinks different cell types, exploring sustainable materials.

Abstract Droplet splitting technology presents considerable potential for advancing applications in sample encapsulation, manipulation, chemical reaction control, and precision measurement systems. However, existing methodologies frequently encounter limitations related to complex operation high cost. To address the need controllable, high‐precision, cost‐efficient droplet splitting, this study combines three‐dimensional printing with superhydrophobic surface modification fabricate pyramid microstructures customized functionalities. The pyramidal sharp edges act as “fluidic blades” split droplets through synergistic interaction of edge‐induced capillary forces inertial generated at liquid film periphery during spreading dynamics. Upon penetration by apex, forms an annular ring that subsequently fragments into sub‐droplets, enabling programmable splitting. A comprehensive experimental computational framework was developed investigate dynamics, force distribution patterns, geometric dependence structures on performance. Results indicate increased Weber numbers, larger volumes, reduced apex angles markedly improve controllability. Additionally, six‐ 12‐sided pyramid‐based splitting/collection devices were engineered demonstrate practical implementations, including on‐demand marble synthesis. This work establishes a scalable, low‐cost platform manipulation significant implications microfluidic lab‐on‐a‐chip technologies.

Abstract Electrorheological fluids (ERF) have garnered significant attention for their potential to provide actuation on demand. Similarly, developing stimuli‐responsive printable inks flexible electronics is also gaining antecedence. However, a material that demonstrates both functionalities far and few. Accordingly, ink made using silylated carbon nanofiber (SiCNF)‐polydimethylsiloxane (PDMS). The viscosity of the increased by 43%, when subjected an electric field ( E ). Robust stability 20 cycles under = 300 V mm −1 noted. yield stress (τ y ) value 1600% 600 compared zero‐field stress. Applying temperature with further τ . In absence E, applying not only slowed down relaxation modulus but counterintuitively augmented extent sluggishness increase in temperature. A comprehensive study waiting time indicated structure build‐up within composition happening as increases. time‐temperature time‐waiting superposition principle applied predict long‐term behavior inks. Further, printability index check studied used printing designs direct writing. printed demonstrated pressure sensing capability sensitivity 6.3%/kPa stable over 60 cycles.
