Although these are great toys, thats all they are toys. For example the resolution is just .35 mm for most machines, so everything you extrude has steps that have to be sanded out. Take a look at the full size cars they are building with these machines fascinating technology but they look like something you would make with a giant Lego set and these are built with $300,000+ machines. I can foresee amazing possibilities in the not too distant future, when they get the resolution down to something like .05mm they will have a more practical use. The size limitation is also a factor, limiting yourself to a 12 inch cube or smaller means that any large project has to be made in pieces and glued together. I am very excited to see the next generation of these replicators, perhaps even machines that can extrude food. Then you can have a world class chef send his recipes via the internet to your home based machine for you to enjoy an amazing meal ( after cooking it ) without leaving you home ?
