Curved-layered fused deposition modeling demands a curved mandrel for each of the designs to fabricate. This results in more fabrication time and material used. To overcome this, an adaptable pin-base mandrel is presented. The fabrication of curved structures with such mandrel uses the extruder as a pushing tool, pushing each of the pins to the depths required for each surface. After the base surface is formed, the conventional process of curved fused deposition modeling (FDM) is used. Several lattice shell structures composed of nonplanar layers were fabricated on FDM mandrels and the adaptable pin-bed proposed here. The comparison of the manufacturing results showed that the adaptable base allows the successful fabrication of the samples. The solution exposed here represents a proof of concept to validate the idea. The adaptable base presented in this study is unique and it brings advantages to the fabrication of curved-layered structures.

用于非平面结构的弯曲分层熔融沉积建模的自适应床：概念证明

弯曲分层熔融沉积建模需要为每个设计制造一个弯曲的心轴。这导致更多的制造时间和使用的材料。为了克服这个问题，提出了一种适应性强的销基心轴。使用这种心轴制造弯曲结构使用挤压机作为推动工具，将每个销钉推至每个表面所需的深度。基面形成后，采用传统的曲面熔融沉积成型（FDM）工艺。在 FDM 心轴和此处提出的自适应针床上制造了由非平面层组成的几种晶格壳结构。制造结果的比较表明，适应性强的基底可以成功制造样品。此处公开的解决方案代表了验证该想法的概念证明。
