I've been planning to build a 3d printer for 9 months right now, unfortunately delayed by surprise medical bills. My original budget was about $1100. As I was perusing the internet though... I came across the M3D Promega printer. I am blown away by the specs, and I'm trying to use the digital dentist guide to evaluating printers and while not perfect, it seems really good for the price. It has dual extruders, can heat up to 420C with an upgrade, comes with a filtration, has a decent controller, is enclosed, all metal frame, 15x15x15 build space, has rails in one axis. Has anyone else checked this printer out? It is supposed to retail for $3500, but is right now $1580 (started at $1000 originally) and the price goes up every day. I would pay almost that much for a much less capable machine and it has all the features I have wanted. However, I have not built my own 3d printer yet and maybe I'm missing cut corners on the quality front as this seems too good to be true. Has any one checked it out yet? Any opinions?
