Have you thought about replicating your 3-D printer with a 3-D printer since the 3-D printers are self replicating? This way you can have several machines running at the same time creating different or the same project.
The Arduino is essentially an Atmel microcontroller (single-threaded, with onboard RAM and EEPROM), which you can self source for a few dollars each. There are some excellent tutorials over at MAKE Magazine if you need some help getting started: http://makezine.com/category/electronics/arduino/
Wrong-about the peachy. First-the site is too ambiguous! Next, the Polymers are too damned expensive-and well; I don't like being nickeled, and dimed to death! This guy is hoping to be the next great Sandwich maker-well he missed. The liquid resign is at least 60.00 a Liter-holy cow! I can get the same set up he offers @ 89.00!
