3D PEEK Objects Fabricated by Fused Filament Fabrication (FFF) [PDF]
Materials, 2022 PEEK (poly ether ether ketone) materials printed using FFF 3D printing have been actively studied on applying electronic devices in satellites owing to their excellent light weight and thermal resistance. However, the PEEK FFF process generated cavities inside due to large shrinkage has degraded both mechanical integrity and printing reliability. Here,

Fused Filament Fabrication over fabrics – experiments and applications
IOP Conference Series: Materials Science and Engineering, 2021 Abstract The focus of this paper is to explore the use of Fused Filament Fabrication technology, a material extrusion additive manufacturing technology, by depositing melted Polilactic Acid (PLA) over a substrate – fabric - instead of on an empty building tray. The textile’s composition, nozzle and building plate temperature, printed PLA

Fused Filament Fabrication of Small Ceramic Components [PDF]
Materials, 2018 With respect to rapid prototyping of ceramic components, there are known only a few processes (stereo lithography, binder jetting). In this work, a new process chain is described in detail, showing that ceramics can be printed in a very cost-efficient way.

Degradable Nanocomposites for Fused Filament Fabrication Applications [PDF]
Journal of Manufacturing and Materials Processing, 2018 There has been a substantial increase in the use and development of plastics over the last century. However, due to ever-diminishing petroleum feedstocks and growing concern for the environment, there has been a rise in the use of eco-friendly polymers affording similar properties to that of their depleting counterparts.

A study on extruded filament bonding in fused filament fabrication [PDF]
Rapid Prototyping Journal, 2018 Purpose The performance of parts produced by fused filament fabrication is directly related to the printing conditions and to the rheological phenomena inherent to the process, specifically the bonding between adjacent extruded paths/raster. This paper aims to study the influence of a set of printing conditions and parameters, namely, envelope ...

Fused Filament Fabrication of Actuating Objects
Macromolecular Materials and Engineering, 2022 AbstractThermoresponsive objects can be manufactured from shape memory polymers (SMPs) via fused filament fabrication (FFF). Here a new technological approach to obtain thermally actuating objects using an in‐house synthesized, phase segregated poly(ester urethane) (PEU) is introduced.
