類蜂巢結構可以由眾多個最小重複單元所組裝而成，不同最小重複單元彼此間必須藉由適當接頭方可傳遞外載作用力。本研究主要探討不同類型接頭之特點，並且選擇舌槽接頭 (Tongue-and-groove joint) 應用於最小重複單元接頭設計上。含舌槽接頭之最小重複單元，採用3D列印方式加以製作，同時評價舌槽接頭處之緊密程度以及3D列印作為最小重複單元製作方法之優缺點。另外，本研究利用有限元素法套裝軟體ABAQUS進行數值分析，探討由不同尺寸及幾何形狀之最小重複單元所拼接而成類蜂巢結構，其桿件內部彎矩分佈及接頭處密接程度之變化情形及可能。

In this study, repeating elements from a honeycomb-like structure were manufactured using 3D-printing technology. The repeating elements were designed with tongue-and-groove joints to facilitate multiple connections between each other, eventually to be able to form a large-scale honeycomb-like structure. Joints of the printed repeating elements were inspected for ease in assembly. Two-dimensional models of different dimensions and geometrical properties of honeycomb-like structures composed of 3D-printing units were created and analyzed numerically using finite element analysis. As a result, the positions of the inflection points in the assembly where bending moment is equal to zero were identified and then compared to those obtained theoretically.
