FestINNO 2018: 3D Digitisation Helps Unlock Humanity’s Most Powerful Stories

 

There is a wealth of expertise in Slovenia, including in R&D projects that use 3D. This in an area that can comprise anything from concept design to 3D printing as well as reverse engineering, a process in which a specific object is virtually reconstructed in 2D or 3D, said Andrej Žužek of INTRI in one in a series of workshops held on Tuesday, 29 May, at the Faculty of Management, Koper, as part of festINNO 2018.

 

“3D printers are ‘merely’ devices that print objects in three dimensions, so that they have volume,” said Andrej Žužek, adding that clients usually opt for 3D printing when they want their own ‘mini factory’ or are looking for a quick and effective way to get the first prototypes. According to Žužek, the main area of application for this technology is the medical industry, more specifically prosthetics.

“3D scanners are devices that aim to establish points in space by measuring the distance to them. A laser beam is projected onto a surface, while a camera, set at a certain angle, captures data about a specific point. This enables the user to make a point cloud of this surface, and represent it in polygon models,” explained Žužek, who showed the young workshop participants real 3D devices.

3D scanners vary in price from EUR 400 to as much as EUR 22,000, he said, adding that the price of the device increases with its accuracy.

Using 3D printing technology, INTRI has made a model of a reactor cooling pump for GEN energija’s multimedia centre ‘The World of Energy’ in Vrbina, Slovenia, and an electrified model of the Kranj wastewater treatment plant, to mention but a few.

 

3D digitisation is vital to cultural heritage in cases where physical access is constrained, said Andrej Žužek. As an example, he mentioned the Ljubljana Castle, were the company provided some 3D solutions. Further key areas of application include representation for the blind and visually impaired. The 3D technique was also used to reconstruct Giuseppe Tartini’s violin and many other museum artefacts, and in Žužek’s view it is this kind of projects that make the most powerful stories come to life.
