Knowledge Base Repository

In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
Fused Layer Modeling (FLM) is one of the most popular additive manufacturing techniques. Its application is often limited caused by the procedurally anisotropy. This work addresses FLM’s weakness by examining a new path planning concept that replaces printing several adjacent parallel lines, for example in perimeters. The new technique was compared with conventionally manufactured reference samples in tensile tension and three-point-bending tests. The results show an improvement of the tensile strength in build direction of the samples by up to 40% and a reduction of anisotropy by 28%.
