This is the first time my 3D printer attempted to build a job. It still needs a lot of calibration and fine tuning, a level bed, a heated bed etc but this is an important step since its the first time it has extruded plastic in a job situation. This design is intended to be a technology test bed. It has a lot of neat features like easily removable extruder heads and a motherboard equipped to run lots of Arduino functions on top of the primary 3d printing duties.
