Abstract
Due to the rapid growth of 3D printing popularity, including fused deposition modeling (FDM), as one of the most common technologies, the proper understanding of the process and influence of its parameters on resulting products is crucial for its development. One of the most crucial parameters of FDM printing is the raster angle and mutual arrangement of the following filament layers. Presented research work aims to evaluate different raster angles (45°, 55°, 55’°, 60° and 90°) on the static, as well as rarely investigated, dynamic mechanical properties of 3D printed acrylonitrile butadiene styrene (ABS) materials. Configuration named 55’° was based on the optimal winding angle in filament-wound pipes, which provides them exceptional mechanical performance and durability. Also in the case of 3D printed samples, it resulted in the best impact strength, comparing to other raster angles, despite relatively weaker tensile performance. Interestingly, all 3D printed samples showed surprisingly high values of impact strength considering their calculated brittleness, which provides new insights into understanding the mechanical performance of 3D printed structures. Simultaneously, it proves that, despite extensive research works related to FDM technology, there is still a lot of investigation required for a proper understanding of this process.
Highlights
Three-dimensional (3D) prototyping belongs to the most popular topics that have emerged recently
The main technologies used in 3D printing are stereolithography (SLA), selective laser sintering (SLS), laminated object manufacturing (LOM), and fused deposition modeling (FDM) [2]
Materials used for this study were commercial three types of acrylonitrile butadiene styrene filament differ in properties: ABS-X named as 1B and 1W, ABS AT named as 2W provided by F3D Finnotech Sp. z o.o. (Katowice, Poland)
Summary
Three-dimensional (3D) prototyping belongs to the most popular topics that have emerged recently. FDM is a technology based on additive manufacturing where the plastic filament is being drawn to the extrusion nozzle by the knurled feeder. It allows controlling the material’s flow on demand. Printing nozzle at specified temperature starts to melt and extrude small beads of provided thermoplastic material, simultaneously being moved at horizontal and vertical directions, which results in a layer-by-layer deposition. The process results in ready-to-use products, as the material hardens after the nozzle is being moved to another layer of the final product [3]. The described approach allows printing objects of any desired shape following computer-aided design (CAD) [4]
