Strength and Dimension Accuracy in Fused Deposition Modeling : A Comparative Study on Parts Making Using ABS and PLA Polymers

Abstract

Rapid prototyping is a group of techniques used to quickly scale physical parts or assemblies using three-dimensional computeraided design (CAD) data. The process of 3D printing constructs three-dimensional objects from CAD models, usually by adding layers by a layer of material in a row. Therefore it is also called making addictive manufacturing. Along with the development of rapid prototyping, there are many choices of materials on the market to make parts of 3D printing. The material can be in the solid filament, liquid resin, or powder. Solid filament FDM technology material is the most commonly used by industrythese materials such as ABS, PLA, PETG, HIPS, and others. In 3D printing products, several variables can be observed to produces specific responses desirable. Some of the responses are the efficiency of materials, dimensional accuracy of mechanical, and others. This research was conducted to compare ABS and PLA materials in the fused deposition modeling process. The strength and dimensional accuracy are the response that used in this study. The study reports that ABS has more significant tensile strength than PLA. The tensile strength of ABS is 7.66 MPa and 1.79 for PLA. PLA found has a more accurate dimension compare to ABS. Both on length and thickness, deviation of PLA lower than ABS. On a length, deviation of PLA was 0.06 mm and 0.86 for ABS. On thickness, deviation of PLA was 0.04 and 0.05 for ABS.

Study of Electroless Nickel Plating on Rapid Prototyping Model Using Acrylonitrile Butadiene Styrene

“…Ni 2+ + H 2 PO 3 2-→ NiHPO 3 (7) Equations ( 3) to (4) drive the development of Ni-P coating (5). H is generated, while Ni and P are deposited, in equations ( 4) and (5). Nickel precipitates as NiHPO3 as a result of Equation (7).…”

“…The dependability, safety, ease of fabrication, relatively low cost, and range of thermoplastics that can be utilized are the key reasons for this method's popularity and application. Researchers have tried to improve FDM's applicability, develop new materials, and update the FDM method itself since it was originally presented in the early 1990s [5].…”

The Influence of Different Slicer Software on 3d Printing Products Accuracy and Surface Roughness

“…Berbagai penelitian dalam bidang teknologi rapid prototyping sudah dilakukan untuk pengembangan teknologi ini. Dalam penelitian, pemakaian material filamen ABS dan PLA terbukti memberikan sifat mekanis dan ketelitian dimensi yang berbeda pada hasil produk cetak [9].Data masukan untuk pencetakan produk pada mesin 3D printer adalah data stereolithography (stl) dari 3D model hasil dari proses forward engineering maupun reverse engineering dengan menggunakan 3D scanning. Dalam bidang medis kedua teknologi ini digunakan untuk membuat cetakan untuk gigi, untuk merapihkan gigi, membuat prosthesis/gigi palsu [10].…”

Structural Behavior of a Composite Curtain Wall Fabricated by the Fused Deposition Modeling 3D Printing Method

“…Shubham, P. et al [ 15 ] demonstrated that, as the layer thickness decreases, the performance of the 3D printed ABS sample is improved. In addition, Tanoto, Y. Y. et al compared the mechanical properties of PLA and ABS and determined that the tensile strength of ABS is significantly higher than that of PLA; however, its dimensional accuracy is lower than that of PLA [ 16 ]. In this research, tensile strength is prioritized over the accuracy of the sample, and the 3D printed curtain wall belongs to small parts; therefore, ABS was used as the polymer material in this research.…”
