“…Light plays a very important role in both the manufacturing and the manipulation of microstructures [57,[74][75][76]. Light is a pure and safe energy source that can be transmitted to target objects in a noncontact manner, which enables remote control [77][78][79][80].…”

Tethered and Untethered 3D Microactuators Fabricated by Two-Photon Polymerization: A Review

Microactuators, which can transform external stimuli into mechanical motion at microscale, have attracted extensive attention because they can be used to construct microelectromechanical systems (MEMS) and/or microrobots, resulting in extensive applications in a large number of fields such as noninvasive surgery, targeted delivery, and biomedical machines. In contrast to classical 2D MEMS devices, 3D microactuators provide a new platform for the research of stimuli-responsive functional devices. However, traditional planar processing techniques based on photolithography are inadequate in the construction of 3D microstructures. To solve this issue, researchers have proposed many strategies, among which 3D laser printing is becoming a prospective technique to create smart devices at the microscale because of its versatility, adjustability, and flexibility. Here, we review the recent progress in stimulus-responsive 3D microactuators fabricated with 3D laser printing depending on different stimuli. Then, an outlook of the design, fabrication, control, and applications of 3D laser-printed microactuators is propounded with the goal of providing a reference for related research.

“…Estimates based on lab‐scale techniques suggest that fiber sorbents can be fabricated at a cost of less than $60 per kg of sorbent and further reductions are expected as this process is scaled up and taps into the large infrastructure associated with hollow fiber membrane spinning 37 . Recent advances in rapid 3D printing suggest that there are possibilities for this form of manufacturing to compete with fiber spinning; 38 however, unaddressed challenges exist with deploying adsorption materials using these techniques. This concern with manufacturing cost and scalability of the adsorption contactor extends to the adsorption materials themselves as well 39 .…”

“…2PP, which is also known as direct laser writing (DLW), can be classified into two subcategories: in situ DLW ( is DLW) [ 54 , 55 , 56 ] and dip-in DLW [ 57 ]. In the is DLW process, conventionally manufactured microfluidic channels can be filled with a photocurable liquid phase, followed by DLW printing inside the microchannel.…”

“…They reported that their approach has a resolution that is ten times greater than that of CAL, and it is five orders of magnitude faster than 2PP. On the basis of their initial report [ 55 ], this technique is promising for combining both high resolution and fast processing, but has not yet been evaluated for use in the field of microfluidics.…”

Droplet microfluidics—the art and science of forming droplets—has been revolutionary for high-throughput screening, directed evolution, single-cell sequencing, and material design. However, traditional fabrication techniques for microfluidic devices suffer from several disadvantages, including multistep processing, expensive facilities, and limited three-dimensional (3D) design flexibility. High-resolution additive manufacturing—and in particular, projection micro-stereolithography (PµSL)—provides a promising path for overcoming these drawbacks. Similar to polydimethylsiloxane-based microfluidics 20 years ago, 3D printing methods, such as PµSL, have provided a path toward a new era of microfluidic device design. PµSL greatly simplifies the device fabrication process, especially the access to truly 3D geometries, is cost-effective, and it enables multimaterial processing. In this review, we discuss both the basics and recent innovations in PµSL; the material basis with emphasis on custom-made photopolymer formulations; multimaterial 3D printing; and, 3D-printed microfluidic devices for emulsion formation as our focus application. Our goal is to support researchers in setting up their own PµSL system to fabricate tailor-made microfluidics.
