Read and Win: Laser Printing of Functional Materials
This book deals with the fundamentals and applications of laser-induced forward transfer (LIFT) processes, a set of particularly versatile methods of additive manufacturing. LIFT processes are capable of forming defined, functional microstructures at target substrates without the need of additional washing steps as in subtractive manufacturing methods such as lithography.
The first part reviews the fundamentals of LIFT, and the second part elucidates the role of laser-material interactions in LIFT for different materials classes such as metal, ceramics, polymers, soft materials, and nanoparticles. The third part gives an overview of the application range of LIFT, e.g., for laser printing of electronic materials, chemical and biological sensors, proteins and biomaterials, and three-dimensional metallic structures.
The editors have assembled a group of contributors, all experts in the field, providing the readers with a state-of-the-art treatise on the promising LIFT method and encouraging its further development.
About the editors:
Alberto Piqué is Head of the Materials and Systems Branch at the U.S. Naval Research Laboratory He holds a B.S. and M.S. in Physics from Rutgers University and a Ph.D. in Materials Science and Engineering from the University of Maryland. His research focuses on the study and applications of laser-material interactions. He and his group have pioneered the use of laser-based direct-write techniques for additive manufacturing of electronic, sensor and micro-power generation devices.
Pere Serra is professor at the Department of Applied Physics of the University of Barcelona. He received his Ph.D. from that university in 1997. His research has been devoted to multiple topics in the laser materials processing area, from pulsed laser deposition to laser surface treatments. In the last years he has focused his activity on laser microfabrication, with special attention to laser printing technologies for the fabrication of biomedical and printed electronics devices.
G.I.T.: What is your main focus in research, what is your main scientific interest?
In the last 15 years, we have been focusing our research on laser microfabrication technologies, especially on the laser printing of materials in the form of inks or pastes.
Although in the early years of our research on the topic we mostly focused on the printing of electronic and biomaterials, aimed at hybrid electronics and biosensing applications. Current area of interest includes 2D and 3D laser printing of inorganic materials for flexible electronics.
G.I.T.: What was the reason to write the book?
Research on laser forward transfer technologies has experienced an impressive increase in the last 10 years. However, and in spite of the abundant publications on the topic, there was no complete monograph available. In view of that we thought that it would be very interesting to cover that void. Once we realized that it was possible to gather some of the most renowned experts on laser transfer and compose a comprehensive and self-consistent book, we decided to undertake the project.
G.I.T.: What is the target audience for the book?
It is a broad audience, indeed. It ranges from material developers to mechanical, electrical and biomedical engineers, from academic researchers to industrial developers and for those interested in the development of micro-scale additive manufacturing techniques. Not to mention academics, who can benefit from it in advanced courses on materials science and engineering.
G.I.T.: What knowledge is prerequisite for the book?
Although there are a few chapters which are quite technical, a basic background on materials science and engineering will suffice.
G.I.T.: What is the structure of the book?
The book is organized into three main parts. The first one deals with the fundamentals of laser forward transfer. In this part, the main techniques are presented and described in detail, alongside the mechanisms of transfer involved in each of them. The second one focuses on the laser-material interactions, emphasizing those aspects that are specific to each kind of material. The last part is devoted to applications. Laser forward transfer can be used in a wide range of applications, some of them well consolidated in the industry and others still prospective.
G.I.T.: What application do you foresee to become the most important within the next few years?
We would choose two. On one side, printed electronics. The possibility of printing a broad range of materials, from inorganics to polymers, both in solid and liquid phase, and in a digital fashion makes laser forward transfer an excellent choice. On the other side, tissue engineering. With few restrictions concerning the rheology of the materials to print, with a good performance in terms of speed and throughput, and with the possibility of printing living cells without harm laser forward transfer can become a serious competitor before other more conventional techniques. In fact, there are companies already commercializing products on both of those areas.
G.I.T.: If there was one technology that you could advance immediately, which would you chose?
In our opinion, the two applications above mentioned provide the greatest push to commercialize the laser forward transfer process. These two applications are driving the advances in hardware to develop turn-key laser transfer systems. Novel combinations of laser sources and scanners, continuous donor layer configurations and stable suspensions of functional materials specifically formulated for the laser transfer process are the technologies that will enable the transition of laser forward transfer from the lab to the production floor.
