Two-step approach based on fused filament fabrication for high performance graphene/thermoplastic polyurethane composite with segregated structure Ghent University
Fabrication of conductive polymer composites (CPCs) with segregated structure to achieve electromagnetic interference (EMI) shielding is a challenging issue. In this work, a two-step approach based on fused filament fabrication (FFF) technique is proposed to fabricate graphene nanoplatelets (GNPs)/ thermoplastic polyurethane (TPU) composites with segregated conductive networks. The filaments with GNPs/ TPU coating layer were prepared by a ...
Lifting the quality of fused filament fabrication of polylactic acid based composites Ghent University
The development of well-designed polylactic acid (PLA) based composite filaments through fused filament fabrication (FFF) is crucial, as PLA printed parts are characterized by a high brittleness. Here we focus on FFF composite formation using ductile poly (butylene adipate-co-terephthalate) (PBAT), the nanoclay cloisite and the chain extender Joncryl. A high modulus, flexibility, toughness and notched impact strength result upon combining ...
Thermography based in-process monitoring of Fused Filament Fabrication of polymeric parts KU Leuven
© 2019 CIRP Temperature management is crucial in Fused Filament Fabrication (FFF). This paper presents an infrared based set-up able to record spatial and temporal variations during printing of an FFF part, with a field of view of (21.7 × 14.9)mm 2 and at spatial resolution of 30.2 μm. The system is experimentally verified and the captured temperature profiles are compared to numerical data, obtained via an own-developed FFF numerical model. ...
Technical performance of polylactic acid based materials for fused filament fabrication by tuning blend ratios and processing strategies Ghent University
Simulation based determination of the maximum flow rate in fused filament fabrication Ghent University
A semi-skilled fabrication approach of shape-changing interfaces through fused filament fabrication University of Antwerp
The common additive manufacturing techniques like fused filament fabrication (FFF) routinely produce physical, rigid structures. But using this production technique for manufacturing flexible structures with high-end materials such as thermoplastic polyurethane (TPU) is more difficult. Because of its difficulty, the fabrication of these structures requires higher-end machinery, time-intensive fabrication, and skilled users. Therefore, we focus ...
Gaining a better understanding of the extrusion process in fused filament fabrication 3D printing : a review Ghent University University of Antwerp
Effect of extrusion and fused filament fabrication processing parameters of recycled poly(ethylene terephthalate) on the crystallinity and mechanical properties Vrije Universiteit Brussel Ghent University
The production of plastic has grown exponentially over the past few decades and with it the amount of plastic waste leaking in the environment, where it fragments into micro- and nanoplastics. This problematic situation stresses the need for increased plastic collection, recycling and reuse rates. Extrusion-based additive manufacturing (AM) and especially fused filament fabrication (FFF) offer an efficient and effective method to reuse and ...
