A bike for Lorenzo

A codesign project betwen Opendot, TOG, and Lorenzo.

From opendot website: “La bici per Lorenzo è un progetto su misura. Grazie alla digital fabrication oggi è possibile realizzare oggetti personalizzati sulle esigenze del singolo, soprattutto per utenze specifiche che normalmente vengono ignorate dalla produzione di massa.
La bicicletta di Lorenzo si inserisce nel progetto di Opendot e Fondazione TOG “L’oggetto che non c’è”, un percorso condiviso di co-progettazione e integrazione della digital fabrication a servizio e in supporto alla riabilitazione. La progettazione della bicicletta infatti è partita proprio da un incontro con Lorenzo e i suoi genitori, i terapisti di TOG e i progettisti di Opendot, per verificare le necessità specifiche di Lorenzo, analizzare le posture e prendere le misure del bambino.

Lorenzo ha 6 anni e soffre di una patologia neurologica complessa, che rende difficili la gran parte delle azioni quotidiane, tra cui poter andare in bicicletta.

Co-design, personalizzazione e prototipazione rapida hanno reso possibile la produzione di una bici a tre ruote con pedivelle ridotte, sellino ergonomico, supporto per la schiena e manubrio regolabile. Le componenti sono state adattate a partire da alcuni elementi standard, come ad esempio, ruota anteriore da 16″, ruote posteriori da carrello, ruota libera standard, movimento centrale a cassetta. Lo sterzo invece è stato ricavato dal mozzo di una ruota, il telaio è fresato da pannelli di betulla fenolica. Il modello 3D è personalizzato su Lorenzo, ma può essere velocemente adattato alle esigenze di diversi bambini con disabilità differenti.”

60ml Syringe Extruder

Project developed at the +LAB, a 3D printing research lab focused on low-cost 3D printing, and material development for 3D printing technologies, of the Politecnico di Milano.

The files needed to assemble the extruder are on our thingiverse, and can be downloaded and printed on any lowcost FDM 3D printer.

The extruder is designed for a 60ml syringe which is the perfect dimension for the lab experimental printing needs. The syringe model is a luer lock type, which means you can use a lot of different nozzles from the luer lock system.
The extruder is designed for a 3Drag printer (K8200), but you can easily adapt it to other system by designing a customized mount for your machine. 3Drag is a moving bed machine, so the extruder is still during the print without any issue of moving weight. If you use this on other printer models remember to slow down all head movements like print speed, travel speed etc.
The gear reduction ratio is 5:1, which is enough for printing in clay, but not enough for more viscous materials. This ratio has been decided for dimensional constraints of 3Drag printer, but for other machines a 6:1 or 7:1 ratio it is recommended.

Tilt & Shift Camera System

Graduation project of the master course in Design & Engineering of Politecnico di Milano.

The design project is a tilt shift camera system, inspired to the medium format system, but designed around an APS-C sensor (23,6 x 15,7 mm). The system is fully compatible with the lens from any full frame reflex, using the bigger image circle to fully cover the smaller APS-C sensor during lens shifting and tilting.

SwingThing

Enter for the 3D printing contest Design Smash, organized by WeMake.
The contest was a challenge between design teams to develop a printable model around the statement:
“Explains 3D printing to your grandfather”.
The design teams were then matched to a printing team and we had 4 hour to print and assemble the model.
The contest took place in 2012, and we had the chance to meet the first italian startups KentStrapper and Wasp, both with their first 3D printer prototypes, the Laser Cutting service Vectorealism and the just born 3D printing italian comunity.
Our design got the 2° prize.

RCM Scrubberdryer

Third project of the master in Design & Engineering, a scrubberdryer machine. It is a machine utilized to clean the floor of industrial areas and public spaces, it use brushes, water and soap to wash the floor and istantly dryes it up thanks to a wiper blade.
It embodies a really complex project, needing a complete understanding of every sub-assembly to make it work: water tanks, pumping system, steering system, uman interface, battery and electric motors.
