In this work, the influence of milled and chopped carbon and glass fibers on the curing behavior and accuracy of the acrylic-based photopolymer LOCTITE 3D 3860 was investigated. The analysis was performed using working curves and optical methods. A comparison between the two fiber types showed that using glass fibers leads to increased volume efficiency, which improved even more with increasing fiber weight fraction. The fiber length showed no significant influence. Superlogarithmic curing behavior under high exposure doses can be significantly reduced by using either fiber types. The increased volume efficiency compared to the pure photopolymer of glass fiber-filled photopolymers leads to a broadening in the xy-plane due to light scattering. In the case of carbon fibers, the effect is reduced, but with higher fiber weight fraction the achievable cure depth is strongly limited. The derivation of the exposure parameters for an accurate fabrication with fibers has been validated by a topology-optimized lightweight structure.

在这项工作中，研究了研磨和切碎的碳纤维和玻璃纤维对丙烯酸基光敏聚合物LOCTITE 3D 3860的固化行为和精度的影响。使用工作曲线和光学方法进行分析。两种纤维类型之间的比较表明，使用玻璃纤维可提高体积效率，随着纤维重量分数的增加，这种效率甚至会进一步提高。纤维长度无明显影响。使用两种纤维均可显着降低高暴露剂量下的超对数固化行为。与玻璃纤维填充的光敏聚合物的纯光敏聚合物相比，体积效率提高，由于光散射，导致xy平面变宽。如果是碳纤维，效果会降低，但是当纤维重量分数较高时，可达到的固化深度受到很大限制。通过拓扑优化的轻型结构验证了用于光纤精确制造的曝光参数的推导。
