I was discussing this with a colleague of mine last night over a glass of scotch, and I told him I'd pose the question to you guys.

What do you guys and girls believe is the biggest issue that 3D printing must overcome before it will be in the majority of homes?

My answer was speed. They need to print at least 5 times faster than they do now. It's something that will take a lot of innovation to overcome but i truly believe we will see faster printers. He argued with me and said that people "need bigger garages". He doesn't think people will have 3D printers in their homes, but rather in their garages, thus requiring greater garage work space. He believe that SLA and SLS technology is the future and not FDM. He believes that larger printers will win out in the long run, once prices are greatly reduced.

We'd love to hear your input.
