“…The collision outcomes we observe using a continuous jet of SO 5 with a stream of G5 drops correspond to the four regimes described in Planchette et al (2018b) and recalled below for completeness. The occurrence of these regimes is described in figure 3(a) using the geometric parameter L j /D j and the drop Weber number We d .…”

“…The inertial fragmentation of the drops and jet for partial and total wetting conditions are not described by the same critical value of We d or We * , as introduced in Planchette et al (2018b). This calls for a search for a new parameter able to universally describe this transition.…”

“…Finally, this absence may be caused by insufficient inertia or, said differently, by ineffective disturbances. Indeed, the drop spreading around the jet is expected to be very dissipative (Planchette et al 2012;Chen et al 2017;Planchette et al 2018b), and the fragmentation limit at L j /D j ≈ 2 is recovered for We d > 500.…”

Recently, interest has also raised for drop-jet collisions (Planchette, Hinterbichler & Brenn 2018a;Planchette et al 2018b), which has also been called in-air microfluidics (Visser et al 2018). Such collisions typically aim -beside gaining basic knowledge on capillary-inertial systems -at producing advanced capsules or fibres by solidifying the liquid structures formed upon collisions (Kamperman et al 2018).…”

Microfluidics, with its remarkable capacity to manipulate fluids and droplets at the microscale, has emerged as a powerful platform in numerous fields. In contrast to conventional closed microchannel microfluidic systems, free‐boundary microfluidic manufacturing (FBMM) processes continuous precursor fluids into jets or droplets in a relatively spacious environment. FBMM is highly regarded for its superior flexibility, stability, economy, usability, and versatility in the manufacturing of advanced materials and architectures. In this review, a comprehensive overview of recent advancements in FBMM is provided, encompassing technical principles, advanced material manufacturing, and their applications. FBMM is categorized based on the foundational mechanisms, primarily comprising hydrodynamics, interface effects, acoustics, and electrohydrodynamic. The processes and mechanisms of fluid manipulation are thoroughly discussed. Additionally, the manufacturing of advanced materials in various dimensions ranging from zero‐dimensional to three‐dimensional, as well as their diverse applications in material science, biomedical engineering, and engineering are presented. Finally, current progress is summarized and future challenges are prospected. Overall, this review highlights the significant potential of FBMM as a powerful tool for advanced materials manufacturing and its wide‐ranging applications.This article is protected by copyright.
