OTOH, the price has come down because the Chinese have recognized that the majority of 3D printer buyers, especially in the USA, don't know what they're buying and will pay $200-300 for a piece of crap that sort of looks like a 3D printer but barely functions as one. The crappy, cheapo printers and the cheapskates (who care nothing about quality) that buy them have guaranteed that 3D printing will remain a specialist product for years to come.
No. Don't forget that the world is not flat and not everyone has the money to buy non-cheap stuff. Most people from around the world don't have the luxury of choosing between good and crap, there is only choice between crap and nothing. There IS huge demand for lower price and chinese follow it, that's all. Just look at aliexpress orders, there are buyers from all parts of the world.
Recently I printed a very complicated start lever for my friend's chainsaw on my crappy $200 anet printer and it saved him from buying another chainsaw (replacement part is more expensive than chainsaw). Another case were some clips for an old Soviet fridge. Printer quality was more than enough to do these jobs.
Yes, printer quality is crap, acrylic parts cracked and half of year later anet board went bad and I had to replace it with standard arduino/ramps sandwich. Yet, it was light years better than fucking NOTHING, because I don't live in USA and I don't have usanian salary to buy "non-cheap" stuff (which is often same stuff from chinese, just rebranded and may be little tested).
