3D desktop printer
I came across a YouTube video the other day showing a printer that can create 3D objects to meet your designed specs. The 'Objet' printer looked so amazing I thought for sure it was fake but then I did some searching and found the company website describing the product. Not only does it provide amazing models to present and show off, but it also claims to be able to make intricate moving 3D models. Think of the possibilities! If nothing else, Pine Wood Derby races will never be the same.
