Feasibility Investigation of Gears Manufactured by Fused Filament Fabrication [PDF]

open access: yes, 2020
This paper describes the production, quality and tests of plastic gears made by fused filament fabrication (FFF). Different 3D printers of low and high quality and four different materials were tested: PLA, ABS, PA and PA carbon fiber composite. After optimizing the print parameters, various gears were manufactured and tested. The geometry and the test

Fatigue Performance of ABS Specimens Obtained by Fused Filament Fabrication [PDF]

open access: yesMaterials, 2018
In this paper, the fatigue response of fused filament fabrication (FFF) Acrylonitrile butadiene styrene (ABS) parts is studied. Different building parameters (layer height, nozzle diameter, infill density, and printing speed) were chosen to study their influence on the lifespan of cylindrical specimens according to a design of experiments (DOE) using ...

Design of a Fused Filament Fabrication (FFF) 3D-printer

open access: yesNigerian Journal of Technology, 2021
A Fused Filament Fabrication (FFF) 3D-printer was designed, for fabrication 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 × 200mm × 300mm and it uses the Melzi V2 printer control board, coupled with the ...
