Fused deposition modeling (FDM) has become widely used for personal/ desktop cost-effective printers. This work presents an investigational platform, which is used to study the surface roughness quality, and dimensional accuracy of 100% infill density printed parts fabricated by a personal/desktop cost-effective FDM 3D printer using different types of thermoplastic filament materials namely, PLA, PLA+, ABS and ABS+. Varieties of experiments were conducted after the fabricated parts were naturally cooled down for at least three hours to room temperature. During printing work, the nozzle diameter, layer height, nozzle temperature and printing speed were set at 0.3 mm, 0.1 mm, 220˚C and 30 mm/s, respectively. According to the experimentally obtained data results over 10 mm scanned profile and 90˚ measuring direction (perpendicular to building direction), PLA+ thermoplastic filament material shows an excellent surface behaviour and is found to be more accurate while ABS does exhibit high surface roughness, waviness and primary behaviour. Both PLA and ABS+ show good surface performance.
Fused deposition modeling or FDM technology is an additive manufacturing (AM) technology commonly used for prototyping applications which suffer seriously from low levels of fluctuated surface finish quality, demanding some hand finishing tool for even the necessary levels of 3D printed parts. This paper, therefore, aims at giving close attention to the variation in the surface roughness profile between the inner and the outer faces of FDM 3D printed parts based on advanced polylactic acid (PLA+) thermoplastic filament material. The surface roughness is quantitatively analyzed using a contact-type test-rig with a 90° angle measurement on each face along with each zone and sub-zone. The obtained results revealed that the surface finish of the inner faces is rougher than those of the outer faces as regards nozzle temperature, nozzle diameter, infill density and layer height is 220°C, 0.5 mm, 0% and 0.3 mm, respectively. The personal FDM 3D printer is thus confirmed to be an excellent platform, flexible, straightforward and cost-effective.

Background Rapid Prototyping and 3D PrintingRapid prototyping (RP) refers to a collection of new technologies, such as fused deposition modeling (FDM), direct metal deposition (DMD), selective laser sintering (SLS), inject modeling (IJM) and stereolithography (SLA), which can be used to create any desired 3D physical model of a printed part, element, device or artefact faster than before without machining or tooling [1] by layer manufacturing from computer aided design (CAD) data [2] and without a significant increase in time or cost [3]. This rapid growth of the market has placed 3D printers not just in enormously varied industrial settings but also in schools, universities, and homes, and it is therefore often preferable to call these devices a 'personal 3D printer' or 'desktop 3D printer' [4,5]. The range of applications where FDM 3D printer technology can be used is widespread in different fields, ranging from medical [6] to automotive [7] and aeronautics applications [8]. Currently, as RP is moving towards rapid manufacturing, there is an increasing demand for obtaining good surface quality printed parts as this has more influence on how customers assess the quality of the 3D printed parts. FDM TechnologyOpen source fused deposition modeling (FDM) is one of several RP technologies available that is currently attracting attention [9]. The FDM process was established commercially and sold to international trade in the early 1990s in the USA as a form of concept modeling by Stratasys Inc. [10]. Figure 1 shows the schematic concept of the FDM 3D printer process. It begins with a 3D model (or three-dimensional modeling) in a computer aided design (CAD) file in order to calculate the horizontal cross-sections at sufficiently small increments of the layer height of the printed part before converting it to an STL (Stereo-Lithography) format file [11]. The STL (Stereo-Lithog...
