Improving strength in parts is a topic of ongoing study in 3D printing, and thesis student, Rhugdhrivya Rane, at The University of Texas at Arlington , recently tackled the subject further in ‘ Enhancing Tensile Strength of FDM parts using Thermal Annealing and Uniaxial Pressure .’ Rane opens by discussing the revolutionary and disruptive qualities of 3D printing but points out that there are obvious challenges in producing parts that are strong enough for many applications. ‘Inherent deficiency of weak tensile strength’ is often caused by weak polymer interfaces, with insufficient mechanical properties found in the z-plane direction. “This deficiency in mechanical properties is due to the weak Inter-laminar bonding in the adjacent layers of FDM parts leading to an overall reduction in part strength,” states Rane. “Thus, to enhance the use of FDM parts in actual engineering application and not just artistic renderings, the overall anisotropy of the […]
