On the Post-Processing of 3D-Printed ABS Parts

Abstract

Application of Additive Manufacturing (AM) has significantly increased in the past few years. AM also known as three-dimensional (3D) printing has been currently used in fabrication of prototypes and end-use products. Considering the new applications of additively manufactured components, it is necessary to study structural details of these parts. In the current study, influence of a post-processing on the mechanical properties of 3D-printed parts has been investigated. To this aim, Acrylonitrile Butadiene Styrene (ABS) material was used to produce test coupons based on the Fused Deposition Modeling (FDM) process. More in deep, a device was designed and fabricated to fix imperfection and provide smooth surfaces on the 3D-printed ABS specimens. Later, original and treated specimens were subjected to a series of tensile loads, three-point bending tests, and water absorption tests. The experimental tests indicated fracture load in untreated dog-bone shaped specimen was 2026.1 N which was decreased to 1951.7 N after surface treatment. Moreover, the performed surface treatment was lead and decrease in tensile strength from 29.37 MPa to 26.25 MPa. Comparison of the results confirmed effects of the surface modification on the fracture toughness of the examined semi-circular bending components. Moreover, a 3D laser microscope was used for visual investigation of the specimens. The documented results are beneficial for next designs and optimization of finishing processes.

Effect of a Powder Mould in the Post-Process Thermal Treatment of ABS Parts Manufactured with FDM Technology

“…The most promising results to improve quality and mechanical properties have been found in post-manufacturing processes. One study designed and fabricated a device that uses acetone to modify FDM ABS parts surface to enhanced quality by providing smooth surfaces and fix imperfections [ 20 ]. On the other hand, other studies improve dimensional accuracy eliminating edge part defects by the laser-cutting post-process [ 21 ].…”

Study behaviour of ratchet mechanism manufactured with 3D printing technology

“…Consequently, it is a good option for printing objects with relatively big d imensions due to its poor thermal expansion (little or without warping) and for printing weeny elements due to its reduced fusing temperature. In figure 7, on the left side there is the locking ratchet [9,10].…”

ABS/Silicon Dioxide Micro Particulate Composite from 3D Printing Polymeric Waste

“…There is a wide range of polymeric materials used in FFF, such as PLA, nylon, PC, and ABS [ 42 ]. In order to obtain the intended outcome, a proper material and suitable technology should be used.…”
