Filament 3D printing is a variant of the material extrusion process that has gained popularity for customized applications in various fields. Poly(methyl methacrylate) filaments have been utilized in 3D printing for the fabrication of bespoke biomedical devices and components without requiring post-treatment. This study introduces an experimental a...

Thanks to the simplicity and low cost, the open chamber filament material extrusion process, also known as fused filament fabrication (FFF), has spread to customized applications in the fashion and textile industries. This work is an experimental optimization of a 3D printed button changing two primary parameters, the printing speed and temperature...

Purpose New sustainable approaches to fashion products are needed due to the demand for customization, better quality and cost reduction. Therefore, the decoration of fashion products using 3D printing technology can create a new direction for manufacturing science. Design/methodology/approach This study aims to optimize the 3D printing of soft TP...

This investigation examines the results of two variable parameters during the fused deposition modeling (FDM) 3D printing process of conventional polylactic acid (PLA) and organic biocompatible compound material with wood (PLA/W; coconut flour), on ultimate tensile strength, UTS (MPa) and modulus of elasticity E (MPa). The parameter optimization is...

Sustainability denotes that energy consumption and its effects on society should also be considered at the early stages of a product idea, except for the product structure cost. Quality metrics of the fused filament fabrication (FFF) 3D printed parts as time, quality and flexibility are also crucial for the well-being of the production of the eleme...

The current work is a follow-up of previous research published by the authors and investigates the effect of CO2 laser cutting with variable cutting parameters of thin 3D printed wood flour mixed with poly-lactic-acid (PLA/WF) plates on kerf angle (KA) and mean surface roughness (Ra). The full factorial experiments previously conducted, followed a...

The Fused Filament Fabrication (FFF) 3D printing builds physical forms or parts by depositing fused thermoplastic substrates layer by layer with computer-aided manufacturing technology. Pure polymers or composites can be 3D printed with the material deposition FFF process. Many attempts have been presented in the literature to 3D print directly on...

This study investigates the effects of four variables during fused filament fabrication of organic biocompatible composite material, PLA with coconut flour, at the ultimate tensile strength (UTS), and elasticity module (E) of the printed parts. The parameter optimization uses Taguchi L18 design and regression models. The examined deposition variabl...

Fused filament fabrication (FFF) is an additive manufacturing process, which constructs physical items by fused melt material, selectively deposited layer-by-layer through a heated extrusion mechanism. Parameters’ selection and control in FFF are of utmost importance since they significantly affect the surface quality (SQ) and dimensional accuracy...

Wood-flour PLA (PLA/W) composite material is a recyclable new material that is suitable for wood-looking components. This organic material can be found in different wood-flour (WF) compositions recently and is appropriate for the FFF (Fused Filament Fabrication) process. The current research investigates the impact of two key parameters, the nozzle...

This paper investigates the quality performance of FDM 3D printed models with thin walls. The design of experiments method (DOE) was used and nine models of the same size were fabricated in a low-cost 3D printer using polylactic acid (PLA) material. Two limited studied parameters were considered (extraction temperature and wall thickness), each one...

The current study investigates the surface roughness of models produced by a 3D printer. All models were produced by addition of solid material, a process called fused filament fabrication (FFF): initial extrusion into plastic filament, second extrusion and trace-binding during the 3D printing process. A low cost 3D printer Ultimaker was used to pr...
