Development and evaluation of a Fused Filament Fabrication (FFF) 3-D printer
Akinjide Oluwajobi
A Fused Filament Fabrication (FFF) 3-D printer was fabricated by using in part locally sourced materials. The printer design was based on the Replicating Rapid Prototyper (RepRap) open source. The print volume of the printer is 200mm x 200mm x 300mm and it uses the Melzi V2 printer control board, coupled with the Repetier-Host firmware. The 3-D printer utilizes two major thermoplastic materials namely, the Polylactic Acid (PLA) and the Acrylonitrile Butadiene Styrene (ABS). The printer consists of a frame, fabricated from galvanized steel sheets, stainless steel threaded rods and wooded supports. The three main Cartesian axes of the machine were constructed from plain stainless rods with plastic printed parts as supporting members. Test results obtained for the PLA print material showed a dimensional deviation of 0.307 mm from the actual CAD model at a print temperature of 200°C and at a layer height of 0.2 mm. For the ABS filament, a dimensional deviation of 0.620 mm at a temperatu...

This work presents the study of the mechanical properties of tensile strength in specimens produced by the 3D printing process known as Fused Filament Fabrication (FFF). The specimens were printed with polylactic acid plastic material (PLA), with filling variations of 25%, 50% and 100% and with rectangular and honeycomb printing geometries. It was proved through the traction test that as the filler increases, the resistance limit increases. It was also verified that the honeycomb printing geometry presents more resistance than the rectangular one

This article reports on the investigation of the effects of process parameters and their interactions on as-built part quality and resource-efficiency of the fused filament fabrication 3D printing process. In particular, the influence of five process parameters: infill percentage, layer thickness, printing speed, printing temperature, and surface inclination angle on dimensional accuracy, surface roughness of the built part, energy consumption, and productivity of the process was examined using Taguchi orthogonal array (L50) design of experiment. The experimental results were analyzed using ANOVA and statistical analysis, and the parameters for optimal responses were identified. Regression models were developed to predict different process responses in terms of the five process parameters experimentally examined in this study. It was found that dimensional accuracy is negatively influenced by high values of layer thickness and printing speed, since thick layers of printed material t...

The mass application of FDM technology is slowed down due to the difficulty of selecting 3D printing parameters in order to manufacture an article with the required characteristics. This paper reports a study into the impact of 3D printing parameters (temperature, print speed, layer height) on mechanical parameters (strength, elasticity module), as well as on the accuracy of printing and roughness of the surface of a specimen based on thermoplastic (PLA plastic). Several batches of specimens were fabricated for this study in accordance with ASTM D638 and ASTM D695, which were tested for tension, geometric accuracy, and roughness. Based on the experimental data, regression analysis was carried out and the functional dependences of the strength, elasticity module, printing precision, roughness of a surface on 3D printing parameters (temperature, speed, thickness of the layer) were constructed. In addition, the derived mathematical model underlying a method of non-linear programming ha...

In this article, the shape of fused deposition modelling (FDM) 3D printed testing objects is verified with 3D scanning technique. Leapfrog’s Creatr is used as a manufacturing device. The whole process of a materialization is explained – from preparation of a model to preparation of a printer. The study is meant to evaluate dimensional errors of printed parts and to give some advices on how to minimize them.
