The Jet formation in Ring-shape Laser Induced forward transfer

Bioprinting by laser-induced forward transfer for tissue engineering applications: jet formation modeling.

In this paper, a nanosecond LIFT process is analyzed both from experimental and modeling points of view. Experimental results are first presented and compared to simple estimates obtained from physical analysis, i.e. energy balance, jump relations and analytical pocket dynamics. Then a self-consistent 2D axisymmetric modeling strategy is presented. It is shown that data accessible from experime...

Laser-induced Forward Transfer of Ag Nanopaste

Over the past decade, there has been much development of non-lithographic methods(1-3) for printing metallic inks or other functional materials. Many of these processes such as inkjet(3) and laser-induced forward transfer (LIFT)(4) have become increasingly popular as interest in printable electronics and maskless patterning has grown. These additive manufacturing processes are inexpensive, envi...

Laser-Induced Forward Transfer of Pure Metals

Laser Induced Forward Transfer for Materials Patterning

Today, a strong research effort is directed towards the development and integration of new materials, especially of polymers and biomolecules which are essential in pharmaceutical, bioengineering, and sensing applications. In fact, patterning of organic and inorganic materials, in particular enabling precise positioning of different materials with nano and micro scale resolution over large area...

ARTICLES Finite element analysis of blister formation in laser-induced forward transfer

Blister-actuated laser-induced forward transfer (BA-LIFT) is a direct-write technique, which enables high-resolution printing of sensitive inks for electronic or biological applications. During BA-LIFT, a polymer laser-absorbing layer deforms into an enclosed blister and ejects ink from an adjacent donor film. In this work, we develop a finite element model to replicate and predict blister expa...
