Welcome back. In Part 1 I explained the basics of 3D printing up until the time we start the printer itself, ie. the virtual design using Blender.
To get an idea of the printer, this is an introductory video from MiniFactory, which is a Finnish company. It costs 1,500 EUR, about 1,800 USD, and it can print objects using either PLA (a corn starch based substance), ABS plastic, or even nylon. It was delivered almost ready to print, and I think it is an extremely useful and suitable device for entering the fascinating world of 3D printing.
Installation is minimal: you plug in the USB cord, install Repetier Host, run through a calibration routine, place the material spools in the rack, and you’re good to go. The next picture identifies the main parts of the machine – click on the image to see it better.
