Any time objects and their (self-)organization are to be put into use, their models and methods of thinking as well as their designing and manufacturing need to be reinvented. 4D printing is a future technology that is capable of bringing 3D objects to life. This ability, which gives objects the power to change shape or properties over time through energy stimulation from active materials and additive manufacturing, makes it possible to envisage technological breakthroughs while challenging the relationship between people and objects. 4D Printing 1 presents the different facets of this technology, providing an objective, critical and even disruptive viewpoint to enable its existence and development, and to stimulate the creative drive that industry, society and humanity need in the perpetual quest for evolution and transformation.

4D Printing: Fundamentals and Applications explores both autonomic and non-autonomic systems with different stimulus such as temperature, current, moisture, light and sound. In addition, the fifth dimensional aspect using more than one stimulus is outlined for additive manufacturing processes. The book presents both an introduction to the basic understanding of hybrid processes and explores the physics behind the process (in the form of derivation and numerical problems). For the field engineer, applicable codes and standards for each hybrid process are provided. Lastly, case studies are included in each section to provide the reader with a model to explore future research directions. - Begins with the fundamentals of the hybrid additive manufacturing process - Presents a discussion of the physics behind smart material functioning in hybrid additive manufacturing - Includes real world case studies on 4D and 5D printing, as well as a look at future research dimensions

4D-Printed Smart Materials and Structures: Mechanics, Modeling, and Advanced Engineering Applications provides a thorough introduction to the fundamentals of the mechanics, manufacturing, modeling, and applications of 4D printed smart materials and structures. Divided into two sections, the book starts by covering the basic theories, definitions, and fabrication details of 4D printing and various smart materials such as shape memory polymers, stimuli-responsive hydrogels, pneumatic soft actuators, dielectric elastomer soft robots, liquid crystal elastomers, shape memory alloys, and magnetic stimulus structures. The second part then examines the mechanics of these materials and their various applications, covering topics such as variable stiffness, miniature-sized 4D printing, and bi-stable and multi-stable mechanisms. The book also includes a chapter on machine learning in 4D printing and provides applications in mechanical, aerospace, civil, and structural engineering, among others.

In 1984, additive manufacturing represented a new methodology for manipulating matter, consisting of harnessing materials and/or energy to create three-dimensional physical objects. Today, additive manufacturing technologies represent a market of around 5 billion euros per year, with an annual growth between 20 and 30%. Different processes, materials and dimensions (from nanometer to decameter) within additive manufacturing techniques have led to 70,000 publications on this topic and to several thousand patents with applications as wide-ranging as domestic uses. Volume 1 of this series of books presents these different technologies with illustrative industrial examples. In addition to the strengths of 3D methods, this book also covers their weaknesses and the developments envisaged in terms of incremental innovations to overcome them.

Who hasn’t dreamed of seeing matter transformed in a way that suits you? This is the goal of 4D printing, using materials that can change in terms of shape and property under the effect of energy stimulation. From the description of the actions and actuators, the authors show the weaknesses that limit the industrialization of 4D printing processes; these are the modes of energy stimulation. To prepare for the future, two chapters are introduced: “Material-Process Duality in Industrial 4D Printing” and “How to Approach 4D Printing in Design”. If the capture and reuse of 4D printing knowledge is necessary for this objective, the conclusion leaves the existing myth around the 4D printing theme and proposes a “draft” roadmap that should be the subject of reflection and scientific debate on a concept that is still immature, but full of promise.

Additive Manufacturing and 3D Printing Technology: Principles and Applications consists of the construction and working details of all modern additive manufacturing and 3D-printing technology processes and machines, while also including the fundamentals, for a well-rounded educational experience.
