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 ...

Mechanics of Corners in Material Extrusion Additive Manufacturing

Corners are among the most common yet least understood features in material extrusion additive manufacturing (MEAM). They exist in almost all toolpaths, especially lattices and infills, impacting structural integrity and shear flow, especially for fibre composites.

Effective mechanical properties of lattice material fabricated by material extrusion additive manufacturing

Additive Manufacturing, 2014
In this paper, a two-step homogenization method is proposed and implemented for evaluating effective mechanical properties of lattice structured material fabricated by the material extrusion additive manufacturing process. In order to consider the characteristics of the additive manufacturing process in estimation procedures, the levels of scale for ...

Principles of material extrusion in metal additive manufacturing

This study aims to examine the potential effects of additive manufacturing (AM) technology on the principles of metal material extrusion. Additive manufacturing, also known as 3D printing, is an advanced manufacturing method that enables the production of three-dimensional objects by combining materials layer by layer. Compared to traditional extrusion

Material extrusion additive manufacturing of aluminum-based feedstocks

AlSi10Mg is a versatile aluminum alloy widely used in the aerospace and automotive industries due to its high strength-to-weight ratio, corrosion resistance, thermal conductivity, and machinability. It is also one of the most popular aluminum alloys for additive manufacturing (AM) via laser powder bed fusion (LPBF) processes.

The Resolution–Throughput Conflict In Material Extrusion Additive Manufacturing

Advanced Materials
ABSTRACT Material extrusion additive manufacturing enables a wide range of technologies, from microscale functional devices to meter‐scale structural components, yet its broader adoption as a manufacturing platform and, increasingly, as a materials discovery tool remains constrained by a persistent coupling between resolution and ...
