This chapter focuses on the fundamental mechanisms dictating these techniques. Moreover, the corollary of increasing the resolution with stimulated emission depletion will be addressed along with its contemporary scientific challenges. Laser printing techniques are defined as all of the technologies that modify the material to create a new structure in an additive manner with a laser source. Among the plethora of various techniques encompassing both high resolution and malleability, some of the most remarkable ones are the multiphoton polymerization techniques for fabrication and the laser-induced forward transfer (LIFT) for controlled deposition. One is the surpassing of Abbe's diffraction limit with multi-wavelength mechanisms that will be addressed later. The major advantage of LIFT as a laser printing technique is the potential of depositing a vast range of materials, both inorganic and organic, solid or liquid, rendering LIFT a versatile tool to be employed in various crucial fields.
