Abstract：
In this study, we demonstrate the feasibility of rapid volumetric additive manufacturing in the solid state. This additive manufacturing technology is particularly useful in outer space missions (microgravity) and/or for harsh environment (e.g., on ships and vehicles during maneuvering, or on airplanes during flight). A special thermal gel is applied here to demonstrate the concept, that is, ultraviolet crosslinking in the solid state. The produced hydrogels are characterized and the water-content-dependent heating/cooling/water-responsive shape memory effect is revealed. Here, the shape memory feature is required to eliminate the deformation induced in the process of removing the uncrosslinked part from the crosslinked part in the last step of this additive manufacturing process.
摘要：
在这项研究中,我们证明了在固态快速体积增材制造的可行性。这种增材制造技术在外层空间任务（微重力）和/或恶劣环境中特别有用（例如，在操纵期间在船舶和车辆上，或在飞行过程中在飞机上)。这里应用了一种特殊的热凝胶来演示这个概念，也就是说,固态紫外线交联。对所生产的水凝胶进行了表征，并揭示了取决于水含量的加热/冷却/水响应性形状记忆效应。这里,例如,需要形状记忆特征以消除在该增材制造过程的最后步骤中从交联部件去除未交联部件的过程中引起的变形。
