MINING THE DATA
The first step is to get the data required for production. With modern models, this process is quite simple: ABREX receives 3D data directly from ŠKODA under a licence. With older models, things are much more complicated. 3D scanning is needed to get the measurements right. A real vehicle is scanned in the workshop in Divišov using a modern scanner that guarantees minimal deformation of the measurements. The scanner creates the web of anchor points that will ultimately result in a 3D model.
“When a scan is scaled down, the 3D scanner isn’t able to erase the excess points. Even when we’ve pared down the model, it’s still too big and complicated to work with. We can print it on a 3D printer, but that is unusable for the subsequent working of the moulds. There is currently no software able to reduce and simplify the model. 3D data, then, is more of a template for us. When we’re designing the model, we have to adjust the data and manually create each surface. We basically remodel the car from scratch. Having said that, we do still have the advantage of having something to cling to, so deformation is kept to a minimum,” explains Jan Mizera.
