Femtosecond laser pulse inducing hydrophilicty and hydrophobicity on polycarbonate surfaces

, 2019
This study investigated the use of ultrashort femtosecond laser pulses to induce either hydrophilic or hydrophobic surfaces on polycarbonate (PC). It has been observed that controlled modification of wettability could be achieved over a wide range of the

Comparison between Abrasive Water Jet Cutting and Laser Cutting

, 1991
This paper is intended to demonstrate the advantages and disadvantages of laser profiling techniques as compared with the Abrasive Water Jet (AWJ). The growth of AWJ as a cutting tool has provided engineers with a new profiling technique which often ...

Synthesis and characterization of semi-transparent gehlenite ceramic spheres obtained by selective laser sintering

Boletín de la Sociedad Española de Cerámica y Vidrio
Selective laser sintering (SLS) is a novel additive manufacturing technique that has been recently applied to the sintering of powdered materials. In this work, radiation with laser was applied to a ceramic oxide powder blend to develop semi-transparent ...
