The FT-5 is my second 3D printer and was my first full kit 3d printer. I originally bought it because of the size of the build plate (300mmx300mmx400mm) and the community behind it. The main use of this printer has been to print my BB-8.
I have upgraded the hot end to be a E3D Aero hotend with titan extruder. This is a all metal hot end which allows for hotter print temperatures, it also allows flexible filaments to be printed better. I have also changed the gantry cabling to a cat5 cable because I had a break in the original cabling which made me switch to something I could change easily should I need to change the cable again. I have also upgraded the power supply to a menwell 24 volt power supply after the original failed. I have upgraded some of the pieces to custom 3D printed spool holder and new gantry head.
