WRONG

Are you a bot, or did you get this info from AI??
The first commercially available FMD 3d printer was for sale in 2009 and cost about $1000. I still have mine somewhere. It's a peice of shit made of laser cut plywood, but it was the only thing of it's kind at the time.
In 2013 you could buy a cheap chinese reprap build it yourself kit for $200-$300
Today you could get a fully assembled printer for that price range.
