The 3D printing is an advanced manufacturing technique in which the material builds layer by layer to create complex geometry objects 1,2. The selective laser melting (SLM) 3D printed SS316L steel ...

Single-beam femtosecond laser pulses can surpass the diffraction limit of conventional focusing systems, enabling deep sub-waveguide single-spot modifications via nonlinear absorption at the focus.

Since September last year we have been keeping track of 3D imagery released by Google, with the help of our readers who spot the imagery and then let us know in the comments of this post. A big thank ...
