Influence of Triangular Pattern Infill on 3D Printed Torus Mechanical Behavior

Abstract

The torus or toroidal surfaces are geometries that can be easily found in various industrial applications, from containers, devices, cartwheels, design objects and even machine parts, being also a geometric primitive often used in solid constructive geometry. For a better understanding of the torus-type surface mechanical behavior, this paper aims to study the toroidal geometry manufactured from ABS material by using the FDM 3D printing method and subjecting each sample to compression tests to identify the influence of the sample filling percentage in the case of triangular pattern.

On investigation of flexural, morphological, and shape memory properties for 3D printed PLA-PVDF NFs-PLA interleave composite structures for smart gripper applications

“…Table 2 shows the factors affecting the process and their levels, reported by the previous investigators. [41][42][43][44][45][46][47][48][49] The process parameters taken into account for the manufacturing of PLA-PVDF NFs-PLA interleave composite structures include the number of layers of PVDF NFs, NFs layer thickness, and the infill pattern. NFs layers were deposited manually (hand layup placement) in between the composite structures after pausing the 3D printer for 20 s. After 50% completion of the composite structure, the printer was paused for depositing one layer of NFs.…”
