3D printing as the state-of-the-art emerging technology offers a platform for the new industrial horizons. The manufacturing process for creating 3D physical objects done via successive layer-by-layer deposition of materials such as metal, plastic, ceramics, or even living cells. The 3D printing concept was first proposed in the 1980s using stereolithography to make polymer objects. 3D technology could transform manufacturing, global product consumption and supply chains. The cover photo of July 2019 issue describes the structure of a 3D printed objects and to celebrate the 39th anniversary of its innovation.

Raman micro-spectroscopy is recommended as an effective non-destructive method of detection and identification of various sp2 carbon modifications, each being characterized by its own specific set of spectral band parameters (frequencies, intensities, half-widths and contours). The results of the authors obtained for numerous industrial sp2 carbon samples (highly ordered and disordered graphites, turbostratic graphite, glassy carbons, carbon fibers, amorphous sp2 carbon, nanotubes) as well as for natural species (terrestrial natural graphites and shungites, Lunar soil, meteoritic matter) are summarized, analyzed and compared. Literature data are also considered and discussed. The results show that the man-made advanced materials contain the same sp2 carbon modifications as have been found in Nature (on Earth, Moon and in cosmic space). © VBRI Press.
