Nuova cinghia 3D-printed per una Olivetti Programma 101

Un esemplare di Olivetti Programma 101 datato 1969 di proprietà dell’Università di Trieste è stato riparato da Giovanni de Sandre e Gastone Garziera in visita presso lo SciFabLab ICTP. Una cinghia dentata di difficile reperibilità, necessaria per far funzionare la stampante, è stata ottenuta tramite stampa 3D a basso costo, in Nylon, usando OpenSCAD, Slic3r ed una Printrbot Simple Metal. A riguardo potete anche leggere il bell’articolo che Alessandro Ranellucci ha scritto per la webzine della Fondazione Made In Italy.

Low-cost 3D printing of mathematical objects from IMAGINARY.ORG

The ICTP SciFabLab has hosted recently a project related to the challenge of making low-cost replicas of some mathematical surfaces that are part of the educational effort of IMAGINARY.ORG. Now the results are presented at a conference in Cape Town (South Africa), here you can find the presentations:

First Desktop Computer at Work After 45 Years! / Olivetti Programma 101 Rimesso in Funzione!

Dopo 45 anni, abbiamo rimesso in funzione un desktop computer Olivetti Programma 101, stampando una cinghia ad-hoc con le nuove stampanti 3D a basso costo presso l’ICTP Scientific FabLab. Il tutto sotto la guida di Gastone Garziera durante la sua visita con Giovanni de Sandre, entrambi dal gruppo originale di progettisti e sviluppatori di Pier Giorgio Perotto dell’Olivetti di Ivrea.

Making a desktop computer Olivetti Programma 101 work after 45 years by using an ad-hoc soft belt printed with the new low-cost 3D printers of the ICTP Scientific FabLab in Trieste, Italy; under the guidance of Gastone Garziera, during his visit together with Giovanni de Sandre, from the famous Pier Giorgio Perotto’s Group at Olivetti, Ivrea.

Invito

This Friday, October 24, ICTP’s SciFabLab will celebrate the history, present, and future of Italian innovation with a special event open to the public

The programme will begin with an exhibit of “Olivetti Programma 101,” the world’s first desktop computer, at the SciFabLab in the Enrico Fermi building from 10:00 to noon.  Giovanni de Sandre and Gastone Garziera, the two remaining members of the team of four Olivetti engineers who designed and built this revolutionary machine first produced in 1965, will be present.

ICTP a SciFabLab @ MakerFaire Rome!!!

During the period 3-5 October our SciFabLab will be present as exhibitor at the MakerFaire in Rome, therefore the normal activities and opening time will be suspended from 2 to 5 October. We will resume the normal schedule on Monday, Oct. 6th.

Nel periodo dal 3 al 5 ottobre il nostro SciFabLab sarà presente come espositore alla MakerFaire Rome, perciò le normali attività e l’apertura al pubblico saranno sospese dal 2 al 5 ottobre. Riprenderemo l’orario consueto con lunedì 6 ottobre.

Mostra Matematica IMAGINARY utilizzando stampanti 3D a basso costo

imaginary

Abbiamo fatto un tentativo di riprodurre degli oggetti della mostra “IMAGINARY Open Mathematics Exhibition” (www.imaginary.org), utilizzando delle stampanti 3D desktop a basso costo. Il progetto internazionale “IMAGINARY Open Mathematics Exhibition” dell”Istituto tedesco “Mathematisches Forschungsinstitut Oberwolfach” comprende gallerie di oggetti tridimensionali che sono unici, attraenti esteticamente ed hanno un significato matematico. Qui si illustra la realizzazione di vari oggetti didattici, utilizzando la nuova tecnologia di stampa 3D a basso costo, basata sulla tecnica di produzione additiva di tipo “Fused Deposition Modeling” (FDM) e l”uso di plastica biodegradabile online casino PLA. L”obiettivo finale e” quello di supportare i musei, le scuole e gli istituti di istruzione superiore nei paesi meno attrezzati di infrastrutture scientifiche.

IMAGINARY Math Exhibition using Low-cost 3D Printers

We have made an attempt to reproduce few objects of the IMAGINARY Open Mathematics Exhibition (www.imaginary.org) using low-cost, desktop 3D printers. The IMAGINARY open math is an international project by the Mathematisches Forschungsinstitut Oberwolfach in Germany and includes galleries of volumetric objects that are unique, have aesthetic appeal and mathematical meaning. We illustrate here the printing of these diverse learning materials using new 3D affordable printing technologies based on Fused Deposition Modelling (FDM) and the use of biodegradable plastic PLA. The final goal is to support museums, schools and higher education institutions in countries with limited scientific infrastructure.
