I almost dropped the money on it this week. Compared to other crowd-funded printers, this is a very low risk investment. Like I said, the components being used are standard RAMPS and LCD, good sized steppers, extruded aluminum, and an all-metal hotend (wish he would keep the hex one instead of redesigning one). Even if the final printer delivered ends up being a let-down, the parts alone recapture most of your investment. Thats why I consider it low risk. Since he is shooting for enough volume to make molded parts, there is a decent chance the final product will be at least the same quality as most other crowd-funded printers (read: it will work, but there may be some design flaws that users will find solutions to on their own just like, oh say, Solidoodle, Printrbot, Robo3D, Qu-BD).
Now, realistically this build volume has a major downside not being currently addressed: Heated bed. He promises it at $1M goal. But the big problem is logistics. The only off-the-shelf currently available is silicone heaters. Once you get beyond 8x8" sizes, the cost is usually pretty high. But beyond that, is powering them. The wattage/amperage of a 16x16 silicone heater is so high, you would burn out the traces on the RAMPS. So if your going to control it, you should use a SSR to power the heater. This is all regurgitated info from previous discussions.
Still, for $300 that build volume for PLA is very tempting. And it would be easy to hack it so that you could make a removable 8x8 PCB heater + glass for ABS (just place it above the standard bed and change homing offset).
I would get this, but I dont want to wait. I have decided that forking over $400 after the crowd-funding is over for quick delivery is better for me.
