Abstract:
Fused deposition modelling (FDM) is one of the most progressive and advanced
Additive Manufacturing (AM) methods for the modern industry. The method has
proven its suitability as a rapid prototyping technique and for the production of
intricate functional components. However, the process faces two major limitations;
poor surface quality and limited range of materials as it is mostly applicable to
polymer-based raw materials. There are therefore extensive efforts by the AM
researchers to enhance the quality of FDM parts and expand its application in
different fields.
This book contributes to these continued efforts by presenting different strategies
for quality enhancement of the technology. In the book, the terms FDM and 3D
printing have been used interchangeably and they have the same meaning. The
book is presented in four chapters. In Chap. 1, a general introduction to the fused
deposition modelling is presented. A glimpse into different methods of AM technology, science of FDM and its applications, process parameters and quality aspects
of FDM technology are presented in this chapter. Most importantly, the role of 3D
printing in the fight against Coronavirus disease of 2019 is discussed in Chap. 1. In
Chap. 2, a full factorial approach for the design of experiment (DOE) based on
different levels of print orientation and layer resolution during FDM of PLA simple
samples is presented as a strategy for enhancing both surface finish and microhardness properties. In Chap. 3, a multi-objective optimization approach is presented as another strategy for quality enhancement of FDM parts using case studies
both from the literature and the experimental work by the authors. Finally, surface
engineering technology is presented as a strategy for enhancing the surface and
functional quality of the FDM parts in Chap. 4.
All the borrowed information such as methods, data and figures have been
acknowledged accordingly inside the text. It is the hope of the authors that the book
will, holistically, contribute towards expanding applications of fused deposition
modelling parts. The book is suitable for engineers, researchers, academics and
industrialists in the 3D printing field.

Description:
In this book, fused deposition modeling (FDM) is described with focus on product quality control and enhancement. The book begins by introducing the basics of FDM and its associated process parameters. Then, strategies for quality control and enhancement are described using case studies of both original results by the authors and from published literature. Resolution and print orientation, multi-objective optimizations and surface engineering are identified and discussed as the strategies for enhancing the quality of FDM products in this book.
