Influence of layer thickness and 3D printing direction on tensile properties of ABS material

Abstract

The 3D printing process is a kind of additive manufacturing, that the basic principle of this process is adding material layer by layer to form a product. The purpose of this research was to study tensile properties of 3D printing ABS (Acrylonitrile Butadiene Styrene) material with axial and lateral direction. The specimen was printed according to ASTM D 632-02 by layer thickness variation around 0.1 mm, 0.2 mm and 0.3 mm. Moreover, three specimens were made for each printing axial and lateral direction. Tensile test was performed using Zwick Roell Series Z 021 machine. Then, the fracture surface was studied by SEM testing used ZEOL JSM-6510LA. Based on the research from 6 variation layer of 3D printing, the optimal result was found on the axial direction of 0.3 mm thickness layer with tensile strength 30.60 MPa and able to receive maximum load 551.13 N. The lateral direction of 0.3 mm thickness layer has tensile strength 19.42 MPa and able to receive maximum load 349.12 N. The voids were seen at the fracture surface of specimen.

Analysis of Notch Effect in 3D-Printed ABS Fracture Specimens Containing U-Notches

“…FDM consists in the extrusion of heated feedstock plastic filaments through a nozzle tip. The extruded material is deposited layer by layer to build the final component following its corresponding digital model [ 1 ]. This simple, reliable and affordable process is guided by software, which permits the user to import the exact geometry of the desired component.…”

“…Raster orientation and the thickness of the layers or the printing speed are some of the most widely analysed so far. In this context, the literature presents numerous works analysing how tensile properties evolve when modifying printing parameters (e.g., [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]). However the number of works analysing the effects of printing parameters on the fracture behaviour are more scarce (e.g., [ 11 , 12 ]).…”

Homogeneous distribution of lignin/graphene fillers with enhanced interlayer adhesion for 3D printing filament

“…The difference of tensile stress in different orientations can be reduced by utilizing a bigger nozzle as it increases the layer height that can be printed and shift the factor more toward the tensile stress of the polymer utilized, but the drawback will be the printing resolution and finishing. [15] Thus, lignin-GnP composite addition was considered as it can improve the plasticity of the polymer and also enhance the interlayer tensile stress of the ABS composite polymer, enabling to print at complex orientations.…”

“…[13,14] 3D printing direction of ABS polymer also has major effect on the strength of the printed product as much as 30% difference due to interlayer adhesion, therefore incorporation of fillers can be considered to enhance the interlayer adhesion as well as for better tensile properties. [15] Therefore, as it is known, to improve the polymer composites' thermal stability and plasticity, lignin can also be incorporated into 3D printing FDM polymers; however, it will not primarily improve the mechanical properties of the polymer. [8] Thus, reinforcement of a small amount of graphene will be vital to enhance the mechanical and thermal properties of the polymer matrix.…”
