Polymer additive manufacturing by fused filament fabrication

, 2023
This article describes the key stages in additive manufacturing using fused filament fabrication. It shows that heating and melting are a compromise between heat transfer from the extruder and polymer transport. Pressure drop and the force required for extrusion are reported.

Dual feed progressive cavity pump extrusion system for functionally graded direct ink write 3D printing

HardwareX
Material extrusion Additive Manufacturing (AM), is one of the most widely practiced methods of AM. Fused Filament Fabrication (FFF) is what most associate with AM, as it is relatively inexpensive, and highly accessible, involving feeding plastic filament

Hybrid heating in Fused Filament Fabrication process

Abstract Changing the heating regime of the polymer during printing by the Fused Filament Fabrication (FFF) process can produce changes in the behavior of the polymer, but also changes in the characteristics of the printed product. The work proposes to replace the traditional resistive heating system with two hybrid heating systems that bring ...
