Comment speed is not really what they're lacking (Score 3, Insightful) 203
Sure, speed would be nice, but this is not really true:
One of the main issues with 3D printers today is that they lack in one area; speed.
3D printers lack in a whole lot of areas, and speed is not at the top of the list. There are a ton of things that you can't do with a 3d printer because the parts are too large, too intricate, need different materials than 3d printers can handle, or are too expensive to 3d print. As more of those problems are solved, the range of things you can plausibly 3d print expands significantly. Now once you can print something in 12 hours, it's great if you could print it in 2 hours or 20 minutes instead, but just being able to do it at all is the biggest step.
