Summary: A direct ink writing 3D printing approach was used to prepare all-printed flexible micro-supercapacitors using rationally designed PEDOT:PSS/MXene composite gels as inks. The MXene nanosheets in the printable inks can enhance the printability of PEDOT:PSS solution and modulate the electronic structures of PEDOT:PSS during a structure transition. The resulting 3D printed micro-supercapacitors and integrated devices exhibit large capacitances, excellent rate performance, and high cycling stability even under exceptional deformations and low temperatures.

Summary: In this study, flexible micro-supercapacitors (MCSs) based on PEDOT:PSS were fabricated using direct ink writing (DIW) printing. Inks with different PEDOT:PSS concentrations were prepared for DIW printing and their rheological properties and printability were investigated. The optimized PEDOT:PSS ink allowed stable printing and the resulting MCS exhibited high energy storage performance and outstanding cycle stability. The flexibility of the PEDOT:PSS electrode enabled the MCS to maintain its performance under bending stress. Furthermore, the practicality of the system was demonstrated by tailoring the overall operating voltage and output capacitance through printing MCSs connected in series and parallel.

Summary: A versatile and reconfigurable direct ink writing (DIW) manufacturing method has been developed to fabricate high-strength, self-supporting parts in unconventional printing spaces. By combining a photopolymer and a tough epoxy resin, this two-stage hybrid DIW ink enables layer-by-layer printing of complex structures and fabrication of large volume structures on diverse substrates. The method demonstrates the capability to print complex structures in inverted and horizontal environments, with the potential for applications such as enhancing functionality, repair, and structure health monitoring by appending new parts to existing structures.

Summary: Digital manufacturing has become the focus of the fourth industrial revolution, where technology blurs the lines between different disciplines. The advantages of digital manufacturing include easy design changes, continuous fabrication processes, and improved cost and speed compared to traditional methods. Laser-induced forward transfer (LIFT) is a versatile fabrication technique that can be used for additive manufacturing of various materials. By selecting appropriate laser parameters and considering material interactions, LIFT can be applied to fragile biological samples.
