Steady melting in material extrusion additive manufacturing

Rapid Prototyping Journal, 2023
Purpose A main cause of defects within material extrusion (MatEx) additive manufacturing is the nonisothermal condition in the hot end, which causes inconsistent extrusion and polymer welding. This paper aims to validate a custom hot end design intended to heat the thermoplastic to form a melt prior to the nozzle and to reduce variability in melt ...

Material Flow Rate Estimation in Material Extrusion Additive Manufacturing

NCSL International measure, 2021
The additive manufacturing of products promises exciting possibilities. Measurement methodologies, which measure an in-process dataset of these products and interpret the results, are essential. However, before developing such a level of quality assurance several in-process measurands must be realized. One of these is the material flow rate, or rate of

Prediction of interlayer strength in material extrusion additive manufacturing

Additive Manufacturing, 2020
Abstract The interlayer strengths of parts produced through material extrusion (also referred to as fused filament fabrication or FFF) suffer due to poor interlayer contact and insufficient diffusion. A model for predicting interlayer contact, based on pressure-driven flow, is combined with a model for polymer chain diffusion to predict the ...
