“Studies and researches left and right has been using 3D printing. The most recent one that was widely publicized in fact was the tiny heart, complete with ventricles and chambers. This time though, researchers have found a way to print even glass.
According to The Optical Society (OSA) Journal Optical Materials Express, a group of researchers headed by Patrick Larochelle (Centre d’Optique, Photonique et Laser at Université Laval in Canada), were able to modify a commercially available 3D printer to print glass. This method of glass printing is based on the commonly used technique of fused deposition modeling, wherein a plastic filament is melted and then extruded layer-by-layer to create detailed 3D objects…”
