advent of smart materials. These materials are called smart due to their self-sensing, self-adaptability, memory capabilities and manifold functions. [1,2] Smart materials are capable of transforming their physical properties (dimensions, shape, stiffness, viscosity, adhesion, and color) following the action of different stimuli, namely, temperature, mechanical strength, electric current, light, magnetic field, chemicals, etc. [3][4][5] A combination of smart materials and 3D printing has resulted in a new field known as 4D printing. 4D printed articles may be used in different fields, including electronics, [2] aerospace industry, [1,2] engineering, [6] sensorics, [2] robotics and medicine. [7] Thermosensitive shape-memory polymers (SMPs) are the most widely studied and used group of materials. [8] In the structure of heat-sensitive SMPs, stiff segments are responsible for the retention of the permanent shape, while flexible segments are responsible for the fixation and retention of the temporary form. [8] Compared with inorganic ceramics and metallic smart materials, SMPs possess such advantages as simpler processing, chemical stability, high stress tolerance, and high recoverable strains. [4] A significant problem of the wide use of both 4D printing and 3D printing in general is a limited range of polymeric Mostof the presently known thermosensitive shape-memory polymers suitable for 4D printing have insufficient mechanical strength and thermal stability that restricts their potential areas of application. Here, new photosensitive compositions (PSCs) based on aromatic heterochain polymers -poly-N,N′-(m-phenylene)isophthalamide (MPA) or poly-2,2′-(p-oxydiphenylene)-5,5′dibenzimidazole (OPBI) -for DLP printing are proposed. Thermal post-curing and supercritical carbon dioxide (scCO 2 ) are used for post-processing of the structures. During the scCO 2 treatment the removal of unreacted monomeric component (N,N-dimethylacrylamide) and its uncrosslinked oligomers is accompanied by the preservation of the initial degree of crosslinking. The more stable shrinkage is observed for the combined post-processing method (T°+scCO 2 ) in the case of OPBI-PSC and after the heat treatment for MPA-PSC specimens. The method of post-processing and the nature of the heterochain polymer strongly affect the mechanical properties and thermal resistance of the structures. The tensile strength has the maximum value after the thermal posttreatment (101.1 ± 7.1 and 78.4 ± 5.1 MPa of OPBI-PSC and MPA-PSC, respectively). The intense destruction of the materials is observed at 393 and 408 °C for MPA-PSC and OPBI-PSC, respectively. Moreover, the 4D-printed structures exhibit excellent shape memory performance at transition temperatures >100 °C, thus have a great potential for the use in aerospace, robotics, sensorics.

Additive manufacturing (or 3D printing) is an evolving technology that shows great potential as a sustainable method for fabricating gas separation membranes for carbon capture applications. Compared to other gas separation techniques or membranes fabricated by conventional formative methods, the use of 3D-printed membranes is more advantageous because of their simplicity, higher energy efficiency, practicality, flexible and tailorable designs, and high separation efficiency. Although polymeric, cementitious, and gel-based materials have been exploited for the development and fabrication of robust and highly efficient CO 2 -capturing membranes, these materials require further innovation to become fit and suitable as feedstock for 3D printers. In this work, we review several and potential membrane materials used for capturing CO 2 and discuss their corresponding separation mechanisms and fabrication via 3D printing. We also summarize the challenges and limitations in using 3D-printed membranes and provide perspectives towards high-performance membrane fabrication and future industrial applications.

“…At first glance, it may be unexpected that many FDM printable polymers exhibit shape memory properties, amongst them quite well-known materials and also more unusual ones, such as bisphenol A epoxy with benzoxazine, 76 (meth)acrylate systems with dynamic imine bonds, 77 polycyclooctene (PCO) 78 or a zincneutralized poly(ethylene-co-methacrylic acid). 79 One of the more often used materials is polyurethane (PU).…”

Shape memory polymers (SMPs) are polymers which ''remember'' their original shape and can return to it after deformation, if an external stimulus-often an increased temperatureis applied. Some SMPs can be 3D printed, typically by fused deposition modeling (FDM). The most well-known SMP is poly(lactic acid), which belongs to the most often used materials in FDM 3D printing. There are; however, many more SMPs which can be 3D printed to combine the possibilities to prepare new, sophisticated shapes with the opportunity to restore these shapes after undesirable or intentional deformation. This review gives an overview of several 3D printable SMPs, their mechanical characteristics and their possible applications.
