In my opinion, current generation 3d printers have to be looked at as tools, not a holy saviour of manufacturing industry. It has it's strong points (fast turnaround times, low price) and has it's weaknesses (subpar resolution, support material is required for many types of parts, being finicky).
Nonetheless, I'm really happy with mine- I built a RepRap around 2 years ago. It took full 1 year to get from starting to read about it, to first prints good enough to be useful. After building, it gathered dust for some time because I didn't know what to do with it- the process of building was more interesting than process of using it :>
That being said, I'm also experimenting with DIY SLA printers- by using UV laser and rotating mirror assembly (found in 2d laser printers). Don't know if it works yet- I'm finishing up electronics/firmware and trying to come up with mechanical design.
