“…Some studies attempted to improve the mechanical properties of FDM polymers by optimising the 3D printing parameters [ 13 , 24 , 25 , 26 ]. However, only a few studies focused on the fatigue behaviour of FDM ABS [ 10 , 27 , 28 , 29 , 30 , 31 ].…”

“…By contrast, Hart and Wetzel confirmed that 90° laminae orientation had the highest fracture toughness [ 30 ]. Padzi et al carried out the fatigue test for ABS dog bone specimens and concluded that the 3D printed part had a lower fatigue life [ 31 ].…”

“…After careful judgement, surprisingly, although there are several printing parameters that may affect the fatigue strength, only a few studies have tested the relationship between them and fatigue performance [ 10 , 27 , 28 , 29 , 30 , 31 ]; furthermore, these studies only investigated one or two specific parameters [ 38 ]. Safai et al and Shanmugam et al presented an overview of the fatigue behavior of 3D printed polymers.…”

Fused deposition modelling (FDM) is the most widely used additive manufacturing process in customised and low-volume production industries due to its safe, fast, effective operation, freedom of customisation, and cost-effectiveness. Many different thermoplastic polymer materials are used in FDM. Acrylonitrile butadiene styrene (ABS) is one of the most commonly used plastics owing to its low cost, high strength and temperature resistance. The fabricated FDM ABS parts commonly work under thermo-mechanical loads in actual practice. For producing FDM ABS components that show high fatigue performance, the 3D printing parameters must be effectively optimized. Hence, this study evaluated the bending fatigue performance for FDM ABS beams under different thermo-mechanical loading conditions with varying printing parameters, including building orientations, nozzle size, and layer thickness. The combination of three building orientations (0°, ±45°, and 90°), three nozzle sizes (0.4, 0.6, and 0.8 mm) and three-layer thicknesses (0.05, 0.1, and 0.15 mm) were tested at different environmental temperatures ranging from 50 to 70 °C. The study attempted to find the optimal combination of the printing parameters to achieve the best fatigue behaviour of the FDM ABS specimen. The experiential results showed that the specimen with 0° building orientation, 0.8 mm filament width, and 0.15 mm layer thickness vibrated for the longest time before the fracture at each temperature. Both a larger nozzle size and thicker layer height can increase the fatigue life. It was concluded that printing defects significantly decreased the fatigue life of the 3D-printed ABS beam.

“…Likewise, the current design of the clip system ensured that no rasters were terminated at edges of the clip system that were loaded with the most stress during usage. Furthermore, fatigue strength of ABS is recorded as 17.8 MPa with 1.9 × 104 cycles [51] and 40% of the ultimate tensile strength in the order of thousands of cycles [52]. The stresses induced in the clip system during fastening or releasing can be considered as negligible due to the nature of light weight tooling that is used for this study.…”

Additively Manufactured Parametric Universal Clip-System: An Open Source Approach for Aiding Personal Exposure Measurement in the Breathing Zone

Design for additive manufacturing is adopted to help solve problems inherent to attaching active personal sampler systems to workers for monitoring their breathing zone. A novel and parametric 3D printable clip system was designed with an open source Computer-aided design (CAD) system and was additively manufactured. The concept was first tested with a simple clip design, and when it was found to be functional, the ability of the innovative and open source design to be extended to other applications was demonstrated by designing another tooling system. The clip system was tested for mechanical stress test to establish a minimum lifetime of 5000 openings, a cleaning test, and a supply chain test. The designs were also tested three times in field conditions. The design cost and functionalities of the clip system were compared to commercial systems. This study presents an innovative custom-designed clip system that can aid in attaching different tools for personal exposure measurement to a worker’s harness without hindering the operation of the worker. The customizable clip system opens new possibilities for occupational health professionals since the basic design can be altered to hold different kinds of samplers and tools. The solution is shared using an open source methodology.

“…The support is manufactured from Acrylonitrile Butadiene Styrene (ABS) using two technologies: 3D printing and injection moulding. ABS fatigue SN curves were defined in SolidWorks (Figure 4) according to research conducted by M. Padzi et al [6] A constant amplitude events with defined cycles test was used for FEA. No interactions were considered in the study and a stress intensity (P1-P3) was considered.…”

The current research aims to develop an experimental stand for functionality testing of an automatic wiping board, to establish its optimal working parameters and select the appropriate materials for functional parts based on Finite Element Analysis (FEA) and experiment results. The conducted research started with the conceptual design of the experimental stand and main component identification. Within this stage, a comprehensive bill of materials is done, ensuring that the specifications of each component are in accordance with its' function within the main assembly. Next, the load cell is fitted with the Arduino board and with a designated computer. The Arduino board is initiated with a programming sequence recommended by the manufacturer and the data acquisition software is programmed using LabView. An initial test of the load cell is undertaken to determine the reading directions and the final experimental stand is assembled. Four tests, each with two travels, are used to analyze the working hypothesis of the wiping board. Results interpretation led to selecting the optimum working parameters of the proposed wiping board concept. The optimum force is used to conduct fatigue FEA on functional parts manufactured from ABS by additive manufacturing and injection molding technologies. Future research includes the integration of a Wi-Fi and an infrared sensor, to enable remote operation of the system. Also, the functional parts will be 3D printed, fitted onto the experimental stand of the automatic wiping board and tested for fatigue using the parameters set in the FEA simulation.
