Sugioka et al. focus on laser direct writing of microfluidic devices and
nano-scale additive manufacturing. Microfluidic devices with three-dimensional
(3D) configurations and multiple functionalities are exceptionally useful for on-chip
construction of artificial biological environments and 3D manipulation of
bio-species in microscale spaces. Direct writing of 3D microstructures having
designable functionalities with femtosecond lasers allows the production of
microfluidic, micro-optic/photonic and microelectronic elements, which can be
monolithically integrated into a single glass substrate for the fabrication of
high-performance biochips. The principles of fs laser direct writing manufacture of
microfluidic, optofluidic, electro-fluidic, and ship-in-a-bottle biochips are introduced herein. Practical techniques and recent advances are reviewed. In addition,
possible future directions in this field are discussed.
In Chap. 9, Zergioti et al. cover the laser-induced forward transfer as a prosing
additive manufacturing. This chapter discusses the fundamental theory supporting
laser printing and specifically laser-induced forward transfer that is a direct
non-contact and non-destructive laser printing technique in an aim to provide a
complete overview of the printing mechanism and the jetting dynamics, while
potential applications are also presented. This chapter is also focused on the evolution of the technique toward additive manufacturing as well as industrialization
activities that have risen in the last five years.
Kirihara reviews that artificial dendrite structures with dendritic geometries and
spatially ordered micro-cavities are successfully fabricated using three-dimensional
stereolithographic printing and ultraviolet laser. The metal and ceramic nanoparticles are dispersed in photosensitive liquid resins to obtain thixotropic pastes. Solid
electrolyte dendrites of yttria-stabilized zirconia have been fabricated for fuel cell
miniaturization. Subsequently, metallodielectric photonic crystals with diamond
lattice structures are printed and demonstrated. Moreover, artificial bones of
hydroxyapatite scaffolds were modeled to realize excellent biocompatibility. The
graded porous structures in the artificial bones were processed.
In the last chapter, Wilhelm et al. report that laser processing technologies for
micro-/nano-structuring of electrode materials in improving the electrochemical
performance and operational lifetime of lithium-ion cells. Different types of laser
structuring are used on metallic current collectors and thin or thick film electrodes.
For thin metallic current collector foils, at anode and cathode sides, the
self-organized structuring by laser-induced periodical surface structures and laser
interference methods is successfully applied for improving electrode film adhesion
and cell impedance. For thin and thick film electrode layers, direct laser ablation
with structure sizes down to the micrometer range and high aspect ratios is found
most powerful in order to create three-dimensional (3D) cell architectures with
benefits regarding cell performance and a homogenous wetting of composite
electrodes with liquid electrolyte. A huge impact of laser formed 3D batteries
regarding capacity retention and cell lifetime at high charging and discharging rates
is detected. A further improvement of 3D battery performance due to an operation
in high potential regime and for advanced high energy silicon anode material has
been achieved by joining of laser structuring and thin film passivation either of
