of trying to integrate two different toy systems.
So this is called a duplo brio connector and
the bottom it connects with Lego duplo blocks.
And on the top across the top is the brio train track.
So this connector allows you to integrate this two different but
in compatible toy systems, so those are solutions.
So we develop this classification and then we randomly picked 500 different objects
on Thingiverse, and then independently my student and I each try to classify
these 500 objects into 1 of these 4 different boxes.
So what do you think we found?
Which category had the most objects?
Well, let's take a look at that.
So as you see here in this next slide that by far and away the biggest category,
over half of these objects, work creations, and
you see the percentages for the other three categories?
And this is interesting because we have to think of 3D printer
as creating existing products, and some individuals will say,
why would I want to make my own whistle when I can buy within the store,
well perhaps you couldn't if the store was an open?
But that's really missing the point, the key point here is that 3D printing
allows us to create new objects that have never been seen before.
So the fact that the majority of these objects,
51% are creations is really interesting.
This suggests that people are using 3D printers
to create new-to-the-world products that have never existed before, and
this is really the magic of 3D printing.
