The third and last day of the 3D workshop was mainly devoted to hands-on activities, where the participants were able to try the techniques learned, slice and print their own objects.
Right before lunch I had my occasion to describe my adventures in kits assembly: my experience for now is with 2 ultimakers, 1 CB printer and 1 Portabee, but I collected some tips and tricks that were well received and could be useful for who wants to choose a printer for himself. Right after Ivan Bortolin (that was present during the whole workshop) was available for who was interested in building a printer from scratch and to describe the technical characteristics of his own printers.
Right after lunch we had the extremely pleasant visit of Fernando Quevedo, the director of ICTP, who thanked all the attendees and was particularly interested in this budding technology and hopeful for the future uses for developing countries.
Following Giancarlo Ghirardi shone light on the principles of tessellation and the always interesting link between science and art. I then gave some quick indications on the use of K3DSurf for generating obj files from mathematical equations.
Daniel Pietrosemoli from MediaLab closed the session with a charming talk on the use of 3D printing for art installation: the Solar Synter by Markus Kayser, Kinect scans, printing joints for bigger structures. Cosmo Wenman and his incredibly detailed sculptures, Abelardo Gil-Fournier (of which we had 2 pieces to study) Marius Watz, David Bowen and the printed onions, and the Fab teletrasportation project that linked makers all over the world making the same cup and drinking together.
During the coffe break all participants were invited to display their 3d printed objects, small masterpieces symbolizing their efforts and successes.
Gregor Luetolf kindly made a bonus speech to show how the distance-controlled print works, setting up a demo in our lab and showing the calibration of the Raspberry pi that controls it. The whole step by step process is also outlined in his blog, 3D-drucken.
Alessandro Ranellucci closed the workshop with an inspiring lecture on the future possible improvements for 3d printers: mixing ink with the filament, new polymers, automated calibration and part removal… many interesting things all of us hope to see implemented soon. The lecture finished with a message on the fact that open hardware helps create low cost machines. Through all of this new technologies are then developed that can really make a difference, like helping people like Liam, a small kid that has substituted his missing hand with a 3d printed one.
This was the last lecture and Enrique Canessa, on behalf of the organizing committee, thanked everyone who has participated (almost 60 during the 3 days) for their enthusiastic envolvement. Various partipants took turns to highlight the most significant moments of the lectures and describing what their future envolvement with this technology could be. Carlo Fonda closed the workshop with a significant statement:
With this workshop Ictp has made a raft, you should build more layers.
