Rheology, crystallization, and process conditions: The effect on interlayer properties in three-dimensional printing
Semicrystalline polymers are an attractive feedstock choice for material extrusion (MatEx)-
based three-dimensional printing processes. However, the printed parts often exhibit poor
mechanical properties due to weak interlayer strength thereby limiting the widespread
adoption of MatEx. Improved interlayer strength in the printed parts can be achieved through
a combination of process parameter selection and material modification but a physics-based
understanding of the underlying mechanism is not well understood. Furthermore, the …
