Hello all! I've been researching 3D printers for a couple months now, and have decided that building my own would be best practice and offer the most satisfaction. Of all the kits I've seen, they say building it yourself is the best way to learn how they work and allows for the easiest troubleshooting during use. I agree with that wholeheartedly. Now most all these kits require you to either purchase and/or print upgrades to get it at top performance. At that point, I might as well just build it myself with the best parts from the gate. The problem is, the best designs I've found all assume you have a 3D printer, CNC machine or cutter to make a good portion of the parts! The one build I'd really like to do is the OneZ i3 by Keith Davis, but I still need printed parts for it to be usable (from what I can tell). The minimum printed part list was showing from $80 - $280 and even as high as $460, from 3dhubs. With prices that high, I question the quality I'd get for $80... I guess the question I need the answer to is: Is there a build that is a good quality, solidly built, intermediate level, Cartesian style 3D printer build that doesn't require printed or machined/milled parts to work?
