Case Study
Harnessing the collective power of ARRK’s Prototyping expertise, know-how andrange of manufacturing solutions to deliver innovations of the future.
ARRK’s Prototyping centre in Barcelona, Spain has held a long standing relationshipwith Elisava, Barcelona School of Design and Engineering over the years. Each year,
students are required to complete a project and produce an exhibition model toshowcase their ideas. So when this year’s final year students from the“Undergraduate Degree in Industrial Design Engineering and Simultaneous Studies
Programme” approached ARRK to help develop their concept, ARRK were only too
happy to help these budding designers of the future.
Their concept was based around a rechargeable battery that could be used to power city
scooters, which riders can share and use around the city. With charging stations locatedacross the city, their concept involved riders calling in at roadside charging units to pick up
a new fully charged battery whilst at the same time popping in the own empty battery into
the recharging station before riding on. This “shared” scooter programme which allows
riders “to hop on and hop off” as they travel around the city, also encouraged customer
loyalty as the more riders used the scooters and exchanged “Onux” batteries, the moreloyal points they would get.

With this vision in mind, the students wanted ARRK to help build a physical model of theirconcept so that it could go on display at their end of year show where lecturers, fellow
students, sponsors and local business leaders could view them.
With time of the essence, ARRK set about helping the students, reviewing their CAD
modelling and its suitability with some of the various 3d printing processes, materials andfinishing options being considered. After discussions, a series of parts were built using
ARRK’s Stereolithography(SLA),Image courtesyof Selective
No Fuss Fill Laser Sintering (SLS) processes across its Spanish
and UK prototyping centres. SLA Clear parts and SLS PA parts were swiftly built and shipped
to our Barcelona team where they finished, assembled and painted to form the outer shellof the battery pack. With the students keen to get hold of the parts as soon as possible,
ARRK were able to turn around parts from receipt of approved CAD and delivered in lessthan ten days.
With final preparations made by the students, the model battery was unveiled to visiting
academics, fellow students and business dignitaries at an end of year show in Barcelona.
We’re delighted to report the event went well and their concept and model well received.
