Fused-filament 3D printing (3DP) for fabrication of tablets [PDF]

International Journal of Pharmaceutics, 2014
The use of fused-filament 3D printing (FF 3DP) to fabricate individual tablets is demonstrated. The technology permits the manufacture of tablets containing drug doses tailored to individual patients, or to fabrication of tablets with specific drug-release profiles.

Effect of Printing Parameters on the Internal Geometry of Products Manufactured by Fused Filament Fabrication (FFF)

, 2023
The internal geometry of a 3D-printed product determines its mechanical properties. In Fused Filament Fabrication (FFF) the filaments that build up the internal geometry suffer from variations that have not been sufficiently studied.

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

, 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

Efficient simulation of the heat transfer in fused filament fabrication

Journal of Manufacturing Processes, 2023
Heat transfer simulations of the fused filament fabrication process are an important tool to predict bonding, residual stresses and strength of 3D printed parts. But in order to capture the significant thermal gradients that occur in the FFF printing process, a fine mesh discretization and short time steps are required, leading to extensive ...

Online Measurement for Parameter Discovery in Fused Filament Fabrication. [PDF]

Integr Mater Manuf Innov
Abstract To describe a new method for the automatic generation of process parameters for fused filament fabrication (FFF) across varying machines and materials. We use an instrumented extruder to fit a function that maps nozzle pressures across varying flow rates and temperatures for a given machine and material configuration. We then develop
