So a while ago, I got myself an Ultimaker
And while I do not want to degrade the usefullness by calling it a toy, I would like to say
Best. Toy. Ever.
It uses a printing technique called FFF, which I guess is just another term for FDM, which builds an object by depositing plastic one layer at a time.
It is sold as a kit, and it took me two evenings (and part of a night) to build.
