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.
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.

To print the mathematical shapes of the project “Math Exhibition”, I’ve selected the Ultimaker printers that are available, amongst others, in the SciFabLab.
There are two of the “original” model, one with a dual extruder.
After months of use, my overall assessment is positive: they are good machines, fast and accurate, despite some minor defect.
For these printers I’ve used the Cura program to “compile” the 3D model and transform it into a set of G-code instructions to send to the printer.
Actually, the Cura command “Load Model File” enables the loading of 3D models in these formats: STL, or OBJ, DAE, AMF, etc.
The first problem that has occurred in Project “Math Exhibition” was the fact that some of the 3D models were provided in X3D format, that “Cura” is not currently able to import.
Before performing other steps, it was necessary to convert the X3D files in STL format.
For this operation I have tested the use of two tools:
Meshlab (open-source, developed by the ISTI – CNR research center, http://meshlab.sourceforge.net/)
Netfabb (http://www.netfabb.com/)
Select: File – Import mesh
Select the x3d file. (for example: distel_200mm_full.x3d).
To export in new file format: File – Esport as:
Select: Project – New Project
Project – Add part
Select the x3d file. (for example: distel_200mm_full.x3d).
To export in new file format: Part – Esport part – as STL (Ascii)

This project aims to build up a low-cost prototype system for cognitive studies around a 360 degrees panoramic vision in real time. The final goal is to have an original broadcast TV channel that transmits and covers live a full 360 degree vision. The first phase of the project is to recreate a pair of 360 degree glasses to understand better the technology and requirements. The final 360 degree transmission will be to display in a modular array of different screens (circular or planar).
Con un po’ di ritardo (il servizio è andato in onda lunedì 18 agosto, l’inaugurazione è avvenuta martedì 12 agosto) pubblichiamo la registrazione di questo servizio, trasmesso durante l’edizione delle 14:00 del Telegiornale Regionale (purtroppo l’edizione delle 19:40, nella quale si è potuto vedere un montaggio differente di immagini ed interviste, non è stata resa disponibile integralmente negli archivi web della RAI).
First tentative for an simple and fast method to produce filament from PET plastic bottles at room temperature (whithout pellets or fusion) by having in mind the possibility of using it for 3D printing at low cost (many improvements are still needed). Work is in progress
Primissimo tentativo per produrre filamento da una bottiglia di plastica PET pensando alla possibilità’ di riciclare facilmente per stampare altri oggetti in 3D usando “additive manufacturing technology”
