Wei Gao,Yunbo Zhang,Devarajan Ramanujan,Karthik Ramani,Yong Chen,Christopher B. Williams,Charlie C. L. Wang,Yung C. Shin,Song Zhang,Pablo D. Zavattieri +9 more
TL;DR: Future directions such as the "print-it-all" paradigm, that have the potential to re-imagine current research and spawn completely new avenues for exploration are pointed out.
Journal ArticleDOI
A review of melt extrusion additive manufacturing processes: I. Process design and modeling
TL;DR: In this article, a systematic review of the literature focusing on process design and mathematical process modeling of FDM and similar extrusion-based additive manufacturing (AM) or rapid prototyping processes is presented.
Journal ArticleDOI
Additive manufacturing methods and modelling approaches: a critical review
TL;DR: In this article, the authors map available additive manufacturing methods based on their process mechanisms, review modelling approaches based on modelling methods and identify research gaps and implications for closed-loop control of the process.
