Abstract

A novel type of lightweight and high-performance, collinear polymer lattices is presented in which the concept of stayed slender columns is exploited with the aid of material extrusion additive manufacturing (MEX). The stays, preventing lower order buckling, are additively manufactured using the printing strategy bridging. Through conducting experimental test series on representative elements and two-dimensional lattices, it is demonstrated that the 3D printed stayed column lattices exhibit significantly improved compressive strength in comparison with conventional collinear lattices. The potential of introducing deliberate geometric imperfections to affect the structural behaviour is furthermore outlined in the current work.

新型轻质平行滞留聚合物晶格的材料挤出增材制造

本文介绍了一种新型的轻质、高性能共线聚合物晶格，借助材料挤出增材制造（MEX）技术，利用了细长支柱的概念。采用打印桥接策略，以快速成型的方式制造出可防止低阶屈曲的支撑杆。通过对代表性元素和二维晶格进行系列实验测试，证明与传统的共线晶格相比，三维打印的支撑柱晶格的抗压强度显著提高。目前的研究还进一步概述了故意引入几何缺陷影响结构行为的可能性。
