Why?

I have looked closely at this item and it has some limited utility for repairing broken plastic and _maybe_ some amusement in *sketching* linear 3D designs. What will anyone do with the 3D sketches? They aren’t very durable or very esthetic. For lost wax processes, there are already wax guns that can make interesting shapes, but even those are lacking precision. I can see a place for 3D printing in making models, but then, you still need molds and casting to get some sort of production.

Personally, this toy is worth _maybe_ $39.95, at most. It is not worth $100 and it is not a 3D printer, handheld or otherwise.

We are professional craftspeople who have been watching the entire 3D development with a lot of interest. It is still in its infancy. It still quite limited. It takes a lot of time to just make a one-off. The printers that can use metal powders and sintering are the most interesting to me and that type has come a long way in the past 20 years. I saw the first sintered titanium jewelry in the late 1980s, when it was still quite crude with an unpleasant surface texture. Intriguing, but it never really took off as even a limited production process.

So, I am curious: what would you dream of doing with this Doodler?
