“…Gadegaard et al [ 156 ] have demonstrated an interesting approach of 3D printing over a large volume with high resolution features by combining nanoimprinting with DLP—where the nanopatterns are created using electron beam lithography and reactive ion etching—and with the part being used as insert for injection moulding. Such an approach could allow higher volume manufacture of microfluidic devices which combine microfluidic channels with other elements such as gratings and fluidic filters.…”

Microfluidic devices offer the potential to automate a wide variety of chemical and biological operations that are applicable for diagnostic and therapeutic operations with higher efficiency as well as higher repeatability and reproducibility. Polymer based microfluidic devices offer particular advantages including those of cost and biocompatibility. Here, we describe direct and replication approaches for manufacturing of polymer microfluidic devices. Replications approaches require fabrication of mould or master and we describe different methods of mould manufacture, including mechanical (micro-cutting; ultrasonic machining), energy-assisted methods (electrodischarge machining, micro-electrochemical machining, laser ablation, electron beam machining, focused ion beam (FIB) machining), traditional micro-electromechanical systems (MEMS) processes, as well as mould fabrication approaches for curved surfaces. The approaches for microfluidic device fabrications are described in terms of low volume production (casting, lamination, laser ablation, 3D printing) and high-volume production (hot embossing, injection moulding, and film or sheet operations).

“…Not surprisingly, variations of SLA printings have also been reported, such as two-photon polymerization (2PP). 2PP relies on a modification of the laser optics and is capable of improving feature resolution down to the nanometer length scale [70]. Of all the 3D printing techniques currently available, 2PP has superior resolution and is capable of fabricating high-quality optical surfaces and microstructures with considerable complexity.…”

This perspective highlights unconventional and emerging approaches to CO2 reduction. These methods encompass the use of topological materials and 3D printing in electrochemistry and the broader fields of plasma- and magneto-electrochemistry. Sustainability in these methods offers a way to convert CO2 into value-added fuels in a circular energy economy. We identify challenges of reducing CO2 along sustainable pathways and detail ways that unconventional approaches can address these challenges. These include achieving high product selectivity toward desirable chemicals, high catalytic durability, high energy efficiency, and high conversion rates of CO2. Finally, we describe emerging impacts and opportunities of these unconventional approaches and key challenges.

“…[38] One of the principal advantages of 3D printing is that it enables planar and 3D architectures to be patterned with controlled composition and structure across a range of length scales spanning from hundreds of nanometers to 1 m or larger. [39] Ink chemistries are tailored to simultaneously satisfy requirements for printability as well as the desired materials properties in the final fabricated structure. [29,[40][41][42] Stereolithography, Digital Light Processing, and DIW serve as important exemplars of 3D printing methods, each harboring specific advantages as a means of 3D fabrication and having different requirements to achieve high print speed and resolution.…”

synthetically. Studying structures found in nature has motivated and will continue to motivate the advancement of 3D fabrication strategies. Progress in this field has seen tremendous growth in recent years and structures that are made with relative ease today, a few decades ago would have seemed impossible. New developments, particularly in the construction of architectures made from soft materials or hybrid structures containing both soft and hard components are continuously emerging. Creation of soft synthetic structures that mimic the properties and functions of biological materials or can interact with, probe, and control living materials continue to drive research in this field.Here, recent contributions from the literature and our research are highlighted and the reports are used to highlight opportunities and current needs for advances in the chemistry of soft materials in the context of their functional integration into 3D architectures of complex form. The methods considered herein serve to highlight a recent paradigm for heterogeneous integration-methods of 4D fabrication exploiting directed assembly and printing to construct complex functional composite material structures.Recent progress in soft material chemistry and enabling methods of 3D and 4D fabrication-emerging programmable material designs and associated assembly methods for the construction of complex functional structures-is highlighted. The underlying advances in this science allow the creation of soft material architectures with properties and shapes that programmably vary with time. The ability to control composition from the molecular to the macroscale is highlighted-most notably through examples that focus on biomimetic and biologically compliant soft materials. Such advances, when coupled with the ability to program material structure and properties across multiple scales via microfabrication, 3D printing, or other assembly techniques, give rise to responsive (4D) architectures. The challenges and prospects for progress in this emerging field in terms of its capacities for integrating chemistry, form, and function are described in the context of exemplary soft material systems demonstrating important but heretofore difficult-to-realize biomimetic and biologically compliant behaviors.
