The 14 and 15 september Sharebot showed up as a technical contributor to the workshop “Italian Nordic Polimer Future” held in the Grand Hotel Duomo of Pisa, organised by prestigious italian and international agiencies as the “Associazione Italiana Macromolecole” and the “European Polimer Federation”.
Sharebot, besides sharing his knowledge on the applications of polimers in the 3D printing processes acquired in the years of development of Sharebot SnowWhite (the sintering 3D printer with a CO2 laser, also present at the workshop) took part in some external projects coming from universities and research centres providing 3D printers, used as testers; during the conferences some publications were presented.
Filament 3D printing and elastic materials
The winner of the poster session, Daniele Rigotti from the University of Trento, presented his research “Multifunctional Materials for 3D printed customizable footwear” showing how to obtain trough 3D printing FFF (Fused Filament Fabrication) process and Sharebot NG, sport shoes soles personalized on the athlete feet, designed to have differentiated bearing in the differet foot areas.
In the specific case, particular interest was given to the material used by Rigotti: a mix of TPU and micrometric particles of paraffin wax, capable of releasing heat when the shoe is brought at temperature under zero degrees celsius.
3D printing with photosensitive resins
Aude-Héloïse Bonardi from the Insitute of Material Science of Mulhouse, conducted a research on photoinitiators with a Sharebot Voyager 2, titled “New photosensitive resins @405nm applications to 3D printing”, in which after explaining the state of the art on the resins comerically aviable did some examples on how photoinitiated chemical sistems can be improved to have better and faster 3D printed results.
Also about resins a really interesting research was displayed by the Professor Massimo Messoni about the in-situ generation of silver nanoparticles in commercial resins, possible with a photo-reduction started by the UV light on bulk prticles of silver dispersed in the metha-acrylate matrix.
Particularly worthy of note Professor Niels B. Larsen (Technical University of Denmark) research on the 3D print of microenvironments wich can replicate biological environments capable of developing cellular in-vivo cultures trough water-base hydrogel resins and controlled radical polimerization.
