Abstract
The application of single homogeneous materials produced through the fused deposition modelling (FDM) technology restricts the production of high-level multi-material components. The fabrication of a sandwich-structured specimen with different material combinations using conventional thermoplastics such as poly (lactic acid) (PLA), acrylonitrile butadiene styrene (ABS) and high impact polystyrene (HIPS) through the filament-based extrusion process can demonstrate an improvement on its properties. This paper aims to assess among these materials, the best material sandwich-structured arrangement design, to enhance the mechanical properties of a part and to compare the results with the homogeneous materials selected. The samples were subjected to tensile testing to identify the tensile strength, elongation at break and Young’s modulus of each material combination. The experimental results demonstrate that applying the PLA-ABS-PLA sandwich arrangement leads to the best mechanical properties between these materials. This study enables users to consider sandwich structure designs as an alternative to manufacturing multi-material components using conventional and low-cost materials. Future work will consider the flexural tests to identify the maximum stresses and bending forces under pressure.
Highlights
Additive manufacturing (AM) began in 1987 when it was known as generative manufacturing or rapid prototyping [1]
The results suggest that increasing acrylonitrile butadiene styrene (ABS) in the ABS/high impact polystyrene (HIPS) blend leads to an increase in the tensile strength and Young’s modulus, but it decreases the elongation at break
This research presented a unique polymer-based sandwich structure to evaluate the tensile properties of different material combinations produced via the fused deposition modelling (FDM) process
Summary
Additive manufacturing (AM) began in 1987 when it was known as generative manufacturing or rapid prototyping [1]. Since it has represented a robust manufacturing development and process of design for products in a wide variety of sectors, including aerospace, biomedical and manufacturing [2,3,4,5]. Material selection methodologies have been developed to choose optimal materials at the early design stages of the AM processes [10]. Marsavina et al [12] studied the tensile properties of two different polyamide materials (PA2200 and Alumide) based on the AM process of selective laser sintering (SLS). Research is being done by combining materials, including polylactic acid and polycarbonate (PLA-PC), acrylonitrile butadiene styrene and polycarbonate (ABS-PC) and polyethylene and polypropylene (PE-PP) [13]
