“…The glass transition temperature of this material is close to the human body temperature and has potential application prospects in the medical field. Shan et al 22 prepared SMP with a strain of up to 90% using 3D printing technology by copolymerizing epoxy acrylate based oligomers with monomer free radicals, which has potential applications in soft robots and flexible electronics. The above studies have made beneficial attempts to improve the mechanical properties of SMP's rubber state, adjust the glass transition temperature, and enhance strain capacity.…”

Experimental and molecular dynamics simulations were employed to investigate epoxy shape memory polymers' thermal‐mechanical properties and shape memory characteristics, utilizing polyether amine and modified hexanediamine as curing agents following the material prerequisites for variable stiffness fixtures. Glass transition temperature and Young's modulus of epoxy shape memory polymers are characterized by dynamic mechanical analysis. The consistency of the glass transition temperature between the simulation model and the experimental findings verified the accuracy of the molecular dynamics simulation. The uniaxial tensile simulation revealed that non‐bond energy predominantly exerts its influence in stretch. After reaching the yield stress, the weight fraction of the curing agent affects the generation of internal pores, with the yield stress of systems exhibiting substantial pores being minor. Systems characterized by a higher weight fraction of curing agents are more prone to pore formulation. Simulation of shape memory properties demonstrates that the entropy resulting from differences in molecular weight impacts the simulated system's shape fixation ratio and shape recovery ratio.

“…Additive manufacturing technologies, such as photocuring 3D printing and LCD 3D printing, offer a flexible and efficient way to produce structures with high resolution and good surface finish [3]. LCD 3D printing exhibits high resolution, which is dependent on the LCD and high efficiency, and can be used to fabricate parts of a wide range of materials, including shape memory polymers [10,11], biomaterials [12], and elastomers [13,14]. However, the mechanical behavior of LCD 3D printed PUA elastomers has not yet been fully investigated, and there is a need to understand how the printing process and other factors may affect the properties of these materials.…”

LCD 3D printing, also known as light during 3D printing or photopolymer 3D printing, is a type of additive manufacturing technology that uses light-sensitive resin to create three-dimensional objects. This technology has gained popularity in recent years owing to its ability to create high-resolution, detailed objects with a wide range of materials, including shape-memory polymers, toughness resins, and elastomers. Elastomers are a type of polymer material that has the ability to stretch and deform under an applied force, but return to their original shape when the force is removed. The superior deformation recovery rate contributes to elastomer use in various industries, including automotive, aerospace, medical, and consumer goods. In this study, we developed a UV-curable polyurethane acrylate(PUA) elastomer with an elongation of 100-200%. Using LCD 3D printing, we were able to fabricate Triply periodic minimal surface(TPMS) lattice structures with this elastomer investigated the compressive behavior of TPMS structures with different compressive ratios of 20%-50%. Our results demonstrate that this approach enables the creation of flexible energy-absorbing structures under cyclic loading. This study highlights the potential of LCD 3D printing technology for the production of elastomeric materials with tunable mechanical properties.
